Frequently Asked Questions - Trumatic C 6002 EH TRUMA

How to set summer mode (hot water only)?

Set the energy selector to gas or electricity. On the control panel, turn the rotary switch to I (40°C or 60°C). Mixed mode is not possible in summer; the unit automatically selects electricity.

How to use heating with hot water production in winter?

Set the desired operating mode on the energy selector (gas, electricity or mixed). On the control panel, turn the rotary knob to the desired room temperature (1-9), then set the rotary switch to n. The green light comes on.

What to do if the red light comes on in gas mode?

The red light indicates a fault. Check that the gas bottle is open, the quick-action valve is open, the flue is clear, and the 12 V supply is sufficient. To reset, turn off and on again. Consult the troubleshooting guide.

How to drain the water heater before frost?

Turn off the 12 V supply to the water pump. Open the hot water taps. Press the control button of the safety/drain valve to position b (drain). Water flows outside. Ensure all 12 liters drain completely.

Can I use the unit on electricity only?

Yes, in electric mode you can choose between 900 W and 1800 W depending on the campsite's protection. It is a secondary heater suitable for mild seasons or to maintain temperature.

What is the role of the ZUC 2 timer?

The ZUC 2 timer is an optional accessory that allows programming of the heating operating times. It connects to the unit via a 3 m cable. For example, it can start the heating before your arrival.

How to reset the 230 V overheating protection?

Let the unit cool down, then open the power electronics cover (13). Press the red button of the overheat switch. Replace the cover.

What gas pressure and regulator to use?

Function description

The Trumatic C 6002 EH combination device combines the benefits of a stationary electric heater with the considerable heating power of an independent gas heater.

Irrespective of whether you just wish to have hot water in summer mode or just heat or heat and hot water in winter mode, 3 power selection options are available:

- Gas only (propane/butane) for independent operation

– Electricity only (230 V) for stationary operation on a camping site

- or Gas and Electricity (simultaneously).

Summer mode (hot water only)

Either gas operation or 230 V electricity operation is used for preparing hot water. The water temperature can be set to 40°C or 60°C.

For gas operation the device automatically selects the smallest burner setting at 2000 W. The water temperature is controlled by the automatic controller, which is powered by 12 V from the vehicle battery.

Depending on the fuse protection at the camping site, power of 900 W (3.9 A) or 1800 W (7.8 A) can be manually selected for electrical operation.

Mixed operation (simultaneous gas and electricity) is not possible. With this setting the device automatically selects electrical operation at the selected power of 900 W or 1800 W. The gas burner is not enabled.

Winter mode (heat and hot water)

All 3 energy selection options can be used for winter deployment.

With gas operation the device automatically selects the burner setting that is required (2000 W, 4000 W or up to 6000 W) depending on the output requirement (calculated from difference between selected temperature and current room temperature). The circulation fan that is needed to distribute the warm air and the automatic room temperature and safety monitoring controller are powered by the vehicle battery (12 V).

Depending on the fuse protection at the camping site, power of 900 W (3.9 A) or 1800 W (7.8 A) can be manually preselected for electrical operation.

If the power requirement is higher (e.g. heating up or low outside temperatures) gas operation or mixed operation must be

selected, since the 230 V electrical heater is only a secondary heater with maximum heating power of 1800 W.

In mixed operation the full heating power of 7800 W (6000 W gas + 1800 W electricity) is available. This combination guarantees rapid heat-up times, even at extremely low outside temperatures. The heating power that is required (calculated from difference between selected temperature and current room temperature) is selected automatically by the unit. If the power requirement is low (e.g. for maintaining room temperature), 230 V electrical operation is given priority. The gas burner is not enabled until the power requirement is higher, and is the first to switch off during heat-up operations.

Heating is always possible in all operating modes (gas, electric and mixed operation) without restrictions, with or without water.

Always observe the operating instructions and „Important operating notes“ prior to starting!

The vehicle owner is responsible for the correct operation of the appliance.

Before using for the first time, it is essential to flush the entire water supply through with clean warm water. If the heater is not being used, always drain the water contents if there is a risk of frost! There shall be no guarantee claims for damage caused by frost! Also drain the water prior to repair or maintenance work on the vehicle (in the workshop!) as the electrical safety/ drain valve opens when the appliance is switched dead!

Please observe the vehicle manufacturer's operating instructions when using vehicle-specific switches.

Room thermostat

s = Room temperature sensor

To measure the room temperature, an external room temperature sensor (s) is located in the vehicle. The location of the sensor is determined individually by the vehicle manufacturer, depending on the vehicle type; consult the operating instructions for your vehicle for further details.

The thermostat setting on the operating element (1 - 9) must be determined individually depending on the heating requirement and the type of vehicle. For an average room temperature of about 23^ , we recommend a thermostat setting of about 6 - 8.

Taking into operation

Before start-up the following must be checked:

1. Is the cowl free? Remove all covers, and open deck cowl if equipment is being used on boats.

2. Are the gas cylinder and the quick-action stop valve in the gas pipe open?

3. Is the fuse protection for the 230 V power supply at the camping site adequate for the selected output (900 W or 1800 W)?

4. Has the power supply cable for the caravan been fully unwound from the cable reel?

i Heating is always possible in all operating modes (gas, electric and mixed operation) without restrictions, with or without water.

Summer mode (hot water only)

1. Select required type of operation at power selector switch (gas or electrical operation).

Mixed operation (gas and electricity) is not possible in summer mode. With this setting the unit automatically selects electric operation at the preselected electrical power of 900 W or 1800 W.

1. Set rotary switch to summer mode (I) 40^ C or 60^ C at control unit.

The green „On“ indicator lamp (k) and the yellow water heating indicator lamp (q) on the control unit illuminate when the equipment is switched on. During electrical operation the yellow indicator lamp (h) at the power selector switch also illuminates to indicate 230 V operation.

When the selected water temperature has been reached (40°C or 60°C) the equipment switches off and the yellow control lamp (q) goes off.

Winter mode

Heating with hot water requirement

1. Select required type of operation at power selector switch (gas, electrical or mixed operation).

2. Move rotary knob (j) on the control panel to desired thermostat setting (1 - 9) for room temperature.

3. Move rotary switch on the control panel to „n”.

The green „On“ indicator lamp (k) and the yellow water heating indicator lamp (q) on the control panel illuminate when the equipment is switched on. During electrical operation the yellow indicator lamp (h) at the power selector switch also illuminates to indicate 230 V operation.

Depending on operating mode (gas, electrical or mixed operation) and power requirement (temperature difference between selected and current room temperature) the unit automatically selects the necessary power setting of up to 7800 W.

The unit gradually reduces the power until the selected room temperature is reached. If this temperature has been reached but the water still has to be heated, the circulation fan switches off and the water continues to be heated to a temperature of 60^ C at the lowest power setting.

The water can be heated to up to 80^ C depending on the heating power that is required to achieve the room temperature.

The yellow indicator lamp (q) indicates the hot water heating phase and goes off when the water temperature is reached (60°C).

Heating without hot water requirement

1. Move rotary knob (j) on the control panel to desired thermostat setting (1 - 9) for room temperature.

2. Select required type of operation at power selector switch (gas, electrical or mixed operation).

3. Move rotary switch on the control panel to „m”.

The green „On“ indicator lamp (k) on the control panel illuminate when the equipment is switched on. During electrical operation the yellow indicator lamp (h) at the power selector switch also illuminates to indicate 230 V operation.

In this operating position the yellow indicator lamp (q) only illuminates at water temperatures of less than 10^ C!

Depending on operating mode (gas, electrical or mixed operation) and power requirement (temperature difference between selected and current room temperature) the unit automatically selects the necessary power setting of up to 7800 W.

When the selected room temperature has been reached, the heater switches off (independent of the water temperature).

The water is automatically heated as well if the boiler has been filled. The water temperature can reach up to 80^ C depending on the power and the duration of the heating.

Switching off

Move rotary switch on the control panel to „p“ to switch off.

The fan can continue to run after switching off in order to utilise the residual heat.

In order to prevent unintentional overloading of the power supply when resuming operation, it is advisable to set the unit to gas operation at the power selector switch after switching off.

Always drain water contents if there is a risk of frost!

If the appliance is not to be used for a prolonged period, close the quick-acting valve in the gas supply line and turn off the gas cylinder.

Gas operation fault

If a fault occurs during gas operation the red indicator lamp (r) on the control panel illuminates.

Possible causes can be found in the troubleshooting list.

Unlocking takes place by switching off and then switching on again.

Opening the window switch and closing it again is the equivalent to switching off/on at the control panel (e.g. performing a fault reset)!

If a fault shut-off occurs during mixed operation (e.g. because of empty gas cylinder) the heater continues to run using electricity.

Electrical operation fault

If a fault occurs during electrical operation the yellow indicator lamp (h) on the power selector switch goes off.

Possible causes can be found in the troubleshooting list.

If the 230 V power supply is interrupted for short periods during operation the heating will resume as normal.

Electrical

safety/drain valve

a b

a = Control knob „closed” b = Control knob „drain“

The safety/drain valve is held closed by a elec- coil. To save battery er, we recommend to the valve if the vehicle in use for a prolonged bed!

If the temperature at the safety/drain valve is less than 4^ C, the water contents may discharge on its own accord if the appliance is not in operation (also if there is a failure)! To avoid water loss, switch the device on (Summer or Winter mode) and close the safety/drain valve at the control knob by raising it up (position a).

Without heater operation, the safety/drain valve can only be closed again at temperatures above 8°C!

The draining socket of the electrical safety/drain valve must always be kept clear (free from slush, ice, leaves etc.)! There shall be no guarantee claims for damage caused by frost!

Filling the water heater

1. Close electrical safety/drain valve at the control knob by lifting up (position a).

At temperatures of around 8^ C and less, switch on the heater or water heater first, to make sure the valve does not open again!

1. Switch on power for water pump (main switch or pump switch).

2. Open hot water taps in kitchen and bathroom, (set preselecting mixing taps or single-lever fittings to "hot"). Leave taps open until the water heater has forced out air and filled up with water and water is flowing out of the taps.

If just the cold water system is being operated, without using the water heater, the heater tank also fills up with water. In order to avoid damage by frost, the water contents must be drained by operating the safety/drain valve, also when the water heater has not been used. As an alternative, two shutoff valves, resistant to hot water, can be fitted in front of the cold and hot water connection.

When connecting to a central water supply (rural or city mains), a pressure reduction valve must always be installed to prevent pressures above 2.8 bar from developing in the water heater.

Draining the

water heater

1. Interrupt power for water pump (main switch or pump switch).

2. Open hot water taps in kitchen and bathroom.

3. Open electrical safety/drain valve at control knob by pressing in (position b).

The water heater content is now emptied to the outside through the safety/drain valve. Place a bucket beneath the outlet to check whether the water content has completely drained away (12 litres!). There shall be no guarantee claims for damage caused by frost!

Maintenance Important operating notes

The water container used is made of stainless steel, which is foodstuff-compatible.

Use wine vinegar for descaling the water heater, this being introduced into the appliance via the water supply. Allow the product to react and then thoroughly flush out the appliance with plenty of fresh water. To sterilise the water we recommend „Certisil-Argento“. Other products, particularly those containing chlorine are unsuitable.

To avoid infestation by micro-organisms, the boiler must be heated to 70^ C at regular intervals (only possible in winter operation).

Do not use the water as drinking water!

Fuses 12 V

The 12 V fuses for the device are located on the electronic control unit (12).

The fine-wire fuse must only be replaced by a fuse of the same design.

F1: 6.3 A, slow-acting

F2: 1.6 A, slow-acting

Fuse 230 V

The fuses and power connection cables must always be replaced by experts!

Disconnect all poles of the unit from the mains before opening the housing containing the power electronics.

The 230 V fuse of the unit is in the power electronics (13) on the unit.

This fine fuse must always be replaced with a fuse of the same type: 10 A, slow, interrupting capacity „H“.

Overheating protection 230 V

The 230 V heating facility has a mechanical overheating switch. If the 12 V power supply is interrupted during operation or during the after-run period, for example, the temperatures within the unit could trigger the overheating protection.

Technical illustration of a mechanical device with a close-up inset showing a component detail (no text or symbols)

To reset the overheating protection, let the heater cool down, slide cover on power electronics (13) upwards and push in the red button.

Always use original Truma spare parts for maintenance and repair work.

1. If the cowl has been placed near or directly beneath an opening window, the device must be equipped with an automatic shut-off device in order to prevent operation with the window open.

2. The integrity and tight fit of the exhaust gas double duct must be checked regularly, particularly at the end of long trips. Also check the mounting of the appliance and the cowl.

3. Following a blow-back (misfire) always have the exhaust gas system checked by an expert!

4. Always keep the cowl for the exhaust duct and combustion air intake free of contamination (slush, ice, leaves etc.).

5. The liquid gas burner operates fan-supported, which ensures trouble-free function even when on the move. National restrictions must be observed with regard to operation when on the move.

6. The installed temperature limiter shuts off the gas supply if the appliance becomes too hot. Therefore do not shut the warm air outlets and the opening for the returning circulating air.

7. The installer or vehicle owner must apply the yellow sticker with the warning information, which is enclosed with the appliance, to a place in the vehicle where it is clearly visible to all users (e.g. on the wardrobe door)! Ask Truma to send you stickers, if necessary.

8. Directive 2004/78/EC stipulates that a safety shut-off device is required if motor homes are being heated while driving. The safety shut-off device is also recommended for safety reasons if caravans are being heated while driving.

The Truma SecuMotion gas pressure regulator meets this requirement.

If no Truma SecuMotion gas pressure regulator is installed, the gas cylinder must be closed whilst driving and information signs must be attached to the cylinder cabinet and in the vicinity of the control panel.

Accessories General safety notes

If the gas system is leaking or if there is a smell of gas:

– extinguish all naked flames
- do not smoke
- switch off the appliances
- shut off the gas cylinder
– open windows and door
- do not actuate any
electrical switches
– have the entire system checked by an expert!

Repairs may only be carried out by an expert!

A new O-ring must always be installed after dismantling the exhaust duct!

1. Any modifications to the unit (including the exhaust duct and the cowl) or the use of spare parts and accessories that are important to the operation of the system (e.g. the time switch) that are not original Truma parts and failure to follow the installation and operating instructions will cancel the warranty and indemnify Truma from any liability claims. It also becomes illegal to use the appliance, and in some countries this even makes it illegal to use the vehicle.

2. The operating pressure of the gas supply must correspond with the operating pressure of the device (30 mbar).

3. Liquid gas systems must comply with the technical and administrative regulations of the respective country of use (e.g. EN 1949 for vehicles or EN ISO 10239 for boats in Europe). National directives and regulations (e.g. DVGW worksheet G 607 for vehicles and G 608 for boats in Germany) must be complied with.

The testing of the gas system must be repeated every two years by a qualified specialist and, if appropriate, confirmed on the inspection certificate (in Germany, for example, DVGW Worksheet G 607 for motor vehicles or G 608 for boats).

The vehicle owner is always responsible for arranging the inspection.

1. Liquid gas equipment must not be used when refuelling, in multi-storey car parks, in garages or on ferries.

2. During the initial operation of a brand new appliance (or after it has not been used for some time), a slight amount of fumes and smell may be noticed for a short while. It is a good idea to heat the device up several times in mixed/summer operation (60°C) and to make sure that the area is well ventilated.

3. If the burner makes an unusual noise or if the flame lifts off, it is likely that the regulator is faulty and it is essential to have it checked.

4. Items sensitive to heat (e.g. spray cans) must not be stored in the installation area, since excess temperatures may under certain circumstances be incurred there.

5. Only pressure regulators that comply with EN 12864 (in vehicles) and EN ISO 10239 (for boats) with a fixed delivery pressure of 30 mbar must be used for the gas system. The flow rate of the pressure regulator must correspond to at least the maximum consumption of all devices installed by the system manufacturer.

For vehicles we recommend the Truma SecuMotion gas pressure regulator and the Truma DuoComfort automatic changeover valve for the two-cylinder system.

At temperatures of around 0^ C or less the gas pressure regulator and the changeover valve must be operated using the EisEx de-icing system.

Controller connecting hoses that meet national regulations must always be used in the respective country for which the equipment is destined. These hoses must be checked regularly for brittleness. Winter-proof special hoses must always be used if the equipment is operated during the winter.

Pressure regulating equipment and hoses must be replaced with new ones no more than 10 years after the date of manufacture (every 8 years if used commercially). This is the responsibility of the operator.

- as a result of using components in the units that are not original Truma parts and using unsuitable gas pressure regulators,
- as a consequence of failure to respect Truma instructions for installation and use,
– as a consequence of improper handling,
- as a consequence of improper transport packing, not arranged by Truma.

2. Scope of warranty

The warranty is valid for malfunctions as stated under item 1, which occur within 24 months after conclusion of the purchase agreement between the seller and the final consumer. The manufacturers will make good such defects by subsequent fulfilment, i.e. at their discretion either by repair or replacement. In the event of manufacturers providing service under warranty, the term of the warranty shall not recommence anew with regard to the repaired or replaced parts; rather, the old warranty period shall continue to run. More extensive claims, in particular claims for compensatory damages by purchasers or third parties, shall be excluded. This does not affect the rules of the product liability law.

The manufacturer shall bear the cost of employing the Truma customer service for the removal of a malfunction under warranty – in particular transportation costs, travelling expenses, job and material costs, as long as the service is carried out in Germany. The warranty does not cover customer service work in other countries.

Additional costs based on complicated removal and installation conditions of the appliance (e.g. removal of furniture or parts of the vehicle body) do not come under warranty.

3. Raising the case of warranty

The manufacturer's address is:

Truma Gerätetechnik GmbH & Co. KG, Wernher-von-Braun Straße 12, 85640 Putzbrunn. In Germany, always notify the Truma service centre if problems are encountered; in other countries the relevant service partners should be contacted (see list of addresses). Any complaints are to be described in detail. In addition, the properly completed guarantee certificate is to be presented, or the factory number of the unit and the date of purchase given.

In order for the manufacturers to be able to determine whether an incident subject to guarantee has occurred, the end user must, at his own risk, bring the device to the manufacturers or send it to them. If there is damage to heaters (heat exchangers), the gas pressure regulator must also be sent back to the factory.

In instances of the device being sent to the works, dispatch is to be effected by freight transport. In cases under guarantee, the works shall bear the transport costs or the costs of delivery and return. If the damage is deemed not to be a warranty case, the manufacturer shall notify the customer and shall specify repair costs which shall not be borne by the manufacturer; in this case, the customer shall also bear the shipping costs.

	- Overheating switch has triggered.	- Reset overheating switch (see Maintenance).

Water supply

When the heating system is switched off, the electrical safety/drain valve opens.	Outside temperature below 4°C.	Switch the heating on (at temperatures of about 4°C and below the drain valve will open automatically).
The valve remains open even after the heating has been switched on.	No 12 V power supply at the drain valve.	Check 12 V supply voltage and fuses.
The electrical safety/drain valve will no longer close.	Outside temperature below 8°C.	Switch the heating on (without heating operation, the drain valve will not close again until temperatures above 8°C have been reached).
The valve remains open even after the heating has been switched on.	No 12 V power supply at the drain valve.	Check 12 V supply voltage and fuses.
Water dripping from the electrical safety/drain valve.	Water pressure too high.	Check pump pressure (max. 2.8 bar).If connected to a central water supply (rural or urban connection), a pressure reducer must be used, which will prevent pressures higher than 2.8 bar entering the boiler.
