Frequently Asked Questions - ESS 9000-T EINHELL

How do I adjust the sauna temperature?

Turn the regulator knob (item 3) clockwise to increase or counterclockwise to decrease the temperature. The range is approximately 40°C to 110°C. Note that the thermometer reading may differ from the set value.

How does the timer function work?

First, ensure the power switch is OFF. Turn the timer knob to the desired delay (e.g., 1 hour). Then switch the power ON – the heating diode will flash to indicate timer activation. The heater will start after the set delay. To change the time, turn off, adjust, and switch on again.

Why is the green operating diode not lighting up?

Check that all three phases contact the 230 V neutral conductor on the incoming wire. If the problem persists, consult a qualified electrician.

What should I do if the heater does not warm up?

Check the overtemperature cut-out resistance (should be ~0 ohms) and the KTY sensor resistance (approx. 1 kOhm at 21°C). Also inspect cables for short circuits or disconnections.

Can I install the sauna controller myself?

Electrical connection work must be performed by a qualified electrician in accordance with VDE 0100 and local regulations. The assembly of the controller case and sensor can be done by the user following the manual.

What are the cable cross-section requirements?

For maximum output (9 kW), use a cross-section of 2.5 mm². Ensure all cables can withstand at least 140°C and use connector sleeves for flexible cables.

How do I connect the sauna light?

Connect the stripped wires (N, L1, PE) as per the terminal diagram inside the controller. The light must be splash-proof (IP54) and able to withstand at least 140°C. Do not mount near the heater.

What is the overtemperature cut-out for?

If the controller fails, the cut-out forces the system to switch off at 127°C to prevent overheating. If tripped, the sensor circuit board must be replaced.

Where should the temperature sensor be installed?

Mount the sensor on the ceiling in the hottest part of the sauna. For a 2m x 2m sauna follow Fig. 4; for larger saunas follow Fig. 5 in the manual.

What does the flashing red LED mean?

A flashing red LED (item 6) indicates that heating is in progress. When the set temperature is reached, the LED turns off. If the LED flashes without heating, check the timer and overtemperature cut-out.

Electrical connection:

Ensure that electrical connection work is performed exclusively by an authorized electrician and that it is in accordance with the guidelines set by the local power supply company as well as the applicable VDE standard for sauna heaters.

It is essential for the controller to be soundly connected to the power supply. The customer is responsible for installing a disconnecting device that disconnects all poles from the power supply at a minimum distance of 3 mm. It also important to ensure that all electrical components, such as cables, lamps, etc. are able to withstand a minimum temperature of 140°C. All flexible cables must have connector sleeves.

Cable cross sections depend on the heater being used and are described in the operating manual of the respective heater. A cross section of 2.5 mm_ should be used in order to obtain the maximum output (9 KW) from the sauna controller.

Important note:

- The neutral conductor (N) of the heater must always be connected to the sauna controller, otherwise malfunctions could occur.

Connecting the sauna heater:

Position the sauna heater in front of the air intake opening as per the assembly instructions provided by the manufacturer and feed the silicon cables through the empty cable conduits up to the controller. Note: If there are no empty cable conduits inside the sauna, drill a hole next to the air intake opening and feed the silicon cable along the outside to the controller through a suitable wiring conduit or cable duct. Connect the stripped ends of the various wires (PE, N, U, V, W) as per the terminal diagram glued inside the controller case.

Connecting the sauna light:

The sauna light must be able to withstand temperatures of at least 140^ and has to be splash proof (IP54). Ensure that the sauna light is never mounted near the heater but always in the place stipulated by the sauna manufacturer.

The power cable must also be able to withstand temperatures of at least 140^ C. Connect the stripped ends of the various wires (N, L1, PE) as per the terminal diagram glued inside the controller case.

Important note:

After installation, all cables must be checked for short circuits. The cable for the overtemperature cut-out is especially important or there will be no guarantee that the controller is switched off in the event of a malfunction.

Connecting the temperature sensor and

overtemperature cut-out

Never place cables designed to withstand 140°C next to the mains cables, otherwise malfunctions could eventually occur.

Note:

The measurements in the diagram below are taken from those listed in device testing regulation EN 60335-53-2. It is essential that the heater sensor is mounted in the part of the sauna where the highest temperatures are to be expected.

Fig. 5

Insert the power cable of the temperature sensor (terminals marked „white“ 1 and 2) and the overtemperature sensor (red 1 and red 2) through the pre-drilled 8 mm hole in the ceiling. Now clamp one of the two wires of the white cable to white

terminal 1 (Fig. 6) and the other wire to white terminal 2 (Fig. 6) of the sensor circuit board. Repeat this process for the red cable by clamping its wires to red terminals 1 and 2 (Fig. 6). Finally, clamp the white cable to the terminals marked "white 1" and "white 2" and the red cable to the terminals marked "red 1" and "red 2" as per the terminal diagram found in the controller case. You can now snap the printed circuit board into the protective case and affix it to the ceiling with the two 3 × 16 mm screws.

Operation and functions

Refer to Figure 7 for the layout of the operator controls.

1 = Heater switch
2 = Light switch
3 = Regulator knob for temperatures of
70°C to 110°C
4 = Regulator knob for timer
5 = Standby diode
6 = Heating mode diode

Operation:

Set switch No. 1 to HEAT, which illuminates the green LED. You can alter the temperature inside the sauna to the desired temperature using the regulator knob. Depending on the temperature in the sauna at the time, the red LED will illuminate to indicate that heating is in process. Turning the regulator clockwise increases the temperature; turning the regulator counterclockwise decreases the temperature. The controllable temperature range is between approx. 40°C and 110°C. Please take into account that the reading you see on the thermometer in the sauna may deviate from the temperature you programmed into the sauna controller as the regulating sensor is located directly in the hot air current of the heater. However, the regulation mechanism is configured so that normal spa temperatures are achieved in the sauna.

Use of the timer:

To set a time when the heating process should begin, turn the timer regulator knob (Fig. 7, Item 1) to the desired time interval.

Timer function:

The power switch (Fig. 7. Item 1) must be turned off. Enter the desired amount of time before heating begins.

Turn on the power switch [timer activation is signified by a flashing heat diode (Item 6)].

Note that, for safety reasons, the time can only be altered when the unit is switched off. Adjusting the regulator (Fig. 7, Item 4) has no effect on the previously entered time. If you would like to alter the previously entered time, you must first turn off the power switch, change the time, then turn the switch on again. The time registered when switching the power on is the new starting time for the timer.

Malfunctions:

If the green operating diode does not illuminate after switching on, check that all 3 phases contact the 230 V neutral conductor on the incoming wire.

The device can be switched on (i.e. green LED is lit), the heater warms up, but the preset temperature is not reached.

• Check the sensor cable.
• Check the power supply to the heater (all 3 phases must contact the zero conductor.)
• The regulator knob must stop when turned all the way to the right and to the left and must not rotate around its axis.

The unit can be switched on, but the heater does not warm up.

• Check the overtemperature cut-out in the sensor
  case. Resistance is approximately 0 ohms.
• Check the KTY sensor in the sensor case.
  Resistance is approximately 1 kOhm at 21°C. Check the cables leading to the sensor case for short circuits and disconnections.
• The unit cannot be switched on but the LED flashes.
• Check the timer. If necessary, turn the timer knob to the left, switch off the controller, then switch it back on.

Check the overtemperature cut-out:

The controller is equipped with an overtemperature cut-out in the sensor case which in the event of overtemperature, e.g. due to a defective controller, forces the system to cut out at 127°C. A tripped overtemperature cut-out is defective and the sensor circuit board must be replaced.

Note for the electrician:

Bridge the overtemperature cut-out (strictly for testing purposes only)
- Measure the voltage at the connector terminals. A defective overtemperature cut-out reads approx. 24 V \~.
