The modulating timer thermostat is an OpenTherm timer thermostat with many enhanced functions. The thermostat is supplied in two versions:

• ThermostatRF(wireless),withthebasestationRFtransmitter This manual covers both versions (OpenTherm and RF). Where information only pertains to one of the two versions then this is clearly stated. A full description of the thermostat can be found in the Installation and Service manual.

The thermostat is menu-controlled, which means it is very simple to operate: it only has three buttons. Menu Program Button A T000059-06-A Display Button B Button C, (push-turn)46

The function of button A and button B depends on the task you are carrying out. The function is shown in the display, immediately above the buttons.

Button C is a push-turn button. You press it to conrmchoices,suchasmenuselections.By turning it you can perform various tasks such as scrolling through menus or changing values such as the temperature, time, date and language. T000153-A48

3.1 Location of the thermostat

The thermostat is set to room control by default, which means that the inside temperature is used to control the central heating. That is why it is best to locate the thermostat on an internal wall in the room in which you spend the most time, such as the living room. Donotlocatethethermostattooclosetoheatsources(replace,radiator,lamp,candles,direct sunlight etc.), or in places where it may be draughty. Thermostat RF The following also apply for the thermostat RF:

washing machines, Tumble driers, wireless telephones, TVs, computers, microwave ovens, etc.

• Positionthethermostatsothatithasgoodreception.Takeaccountofthefactthatobjects containing metal will affect the reception. These include steel-reinforced concrete, mirrors andwindowswithametalcoating,insulatinglmsetc.49

Thermostat RF wireless range The range of the thermostat RF in buildings is generally 30 metres. Note! This value is purely an indication. The actual range of the RF signal depends strongly on the local environment. Remember that the number of walls and ceilings (metal or otherwise) can have a (considerable) impact on reception. Other objects that contain metal may also impact reception. Theseincludemirrorsandwindowswithametalcoating,insulatinglmsetc.

The signal strength can be viewed via Menu > Information.50

3.2 Installation and connection

The following must be done before you install and connect the thermostat:

• AdjusttheboilersothatitcanbeconnectedtoanOpenThermthermostat.

• Turnofftheboiler. Consult the boiler documentation for this process. Do this as follows:

1. Open the housing by pulling the front and the base plate apart.

2. Attach the base plate of the thermostat to the wall using the

screws and plugs supplied. Ensure that the boiler’s connecting wires are protruding through the hole in the base plate.

3. Connect the thermostat to the boiler OpenTherm connection

and the thermostat OT connection. OpenTherm is polarity insensitive; you may therefore swap the wires. T001046-C T000062-C

4. Place three AA batteries in the thermostat if required.

These are not provided. The batteries ensure that the clock keeps running when the boiler is switched off. The batteries also power the backlight for the thermostat for boilers that do not have OpenTherm Smart Power. If you have a boiler with Smart Power, then the backlight for the thermostat also works without batteries. (Thermostat RF only) Place 3 AA batteries in the thermostat. These are required to operate the thermostat RF. T001042-B

The programs that are set are saved if the boiler or the thermostat is switched off (even if there are no batteries). The thermostat RF automatically starts communicating with the base station.

3.3 Location of the outside sensor

An outside temperature sensor is not supplied as standard with the thermostat. You only require this sensor if you want weather-compensated control of the inside temperature. The following guidelines apply with regard to choosing a location for an outside temperature sensor:

Install the outside sensor on the north or north-west side of the home, away from direct sunlight.

• Thesensormustbepositionedatleast2.5metresabovegroundlevel.

• Donotinstalltheoutsidesensornearwindows,doors,ventilationgrills,extractors,etc. Consult the documentation for your boiler for information on connecting an outside temperature sensor.52

3.4 Room sensor (for thermostat RF only)

An RF room sensor is available for the thermostat RF as an option. This sensor replaces the internal thermostat sensor.53

4.1 Setting language, time and date

The menu for selecting the language (international version) or setting the time (Dutch version) appears when you connect the thermostat.

2. Follow the instructions on the display to select the time, year, month and day.

The thermostat is now ready for use. After installation, the default program is activated (see paragraph 4.2). The temperature is now controlled by this clock program.

The thermostat automatically switches between summer time and winter time settings.

Room control Thethermostatissettoroomcontrolbydefault.Thismeansthattheowtemperatureofthe central heating water is controlled by the temperature in the room where the thermostat is installed. Weather-compensated boiler control is also possible (with outside sensor); in other words based on the outside temperature. The thermostat has a programmed heating curve which determines the waterowtemperaturetogetherwiththeoutsidetemperature.Theheatingcurvemustbechosen sothattheleastfavourableroomcanbeefcientlyheatedevenwhentheoutsidetemperatureis very low. See paragraph 5.5 for further information about weather-compensated control.54

Clock program The default clock program sets the temperature each day as follows:

• 23:00–06:00: 15°C+T You can of course adapt the clock programs to your own requirements. See Chapter 5.

The thermostat has three usage modes:

• Basic: no clock programs are used in this mode. You can only set the temperature on the thermostat manually.

• Normal: this is the standard mode. Most options are available, such as the clock program.

• Advanced: this mode lets you use two standard clock programs (A and B), change more settings and request more detailed information. You can change the usage mode via the menu: Menu > Settings > Users > User mode.

This manual deals with most functions relating to the 'Normal' mode. This is the default mode after initial start-up.55

5.2 Creating or changing a clock program

A clock program automatically controls the temperature for a day, and can be set for each individual day. You can adjust the default clock program or enter a completely new program.

The thermostat starts pre-heating prior to the set time by default, so that the room has reached the desired temperature at the correct time. Making an overview It is useful to draw up your own overview with switch times: what temperature does it need to be and when in your home? This of course depends on who is at home when, what time you get up etc. You can set up to six switch times per day.56

An example of an overview is shown below:

Creating a new clock program

1. Select Menu > Program > Clock prog. > New time.

2. Select an initial program if appropriate (Daytime home, Midweek home or Weekend home).

You can now create your own clock program based on this program. PressbuttonCtoconrm.

3. Go to the day for which you want to set the clock program.

You can use the button to remove the selected switch time.

5. Use button C to set the time and the corresponding desired temperature.

6. Once you have set all switch times for a particular day, you can copy the settings for that day

to other days: - Go to the day. - Press Copy. - Select the day(s) to which you want to copy the settings using button C and press Save.

7. Go to the day. Then press button C.

8. Go to step 3 to set the next day, or press Back to close this menu.58

Changing an existing clock program

1. Select Menu > Program > Clock prog. > Change.

2. Go to the day for which you want to change the clock program.

You can use the button to remove the selected switch time.

4. Use button C to set the time and the corresponding desired temperature.

5. Once you have set all switch times for a particular day, you can copy the settings for that day to

other days: - Go to the day. - Press Copy. - Select the day(s) to which you want to copy the settings using button C and press Save.

6. Go to the day. Then press button C.

5.3 Setting continuous temperatures

Instead of the clock program, you can also set the room temperature continuously to a particular value. You can set three different continuous temperatures via Menu > Program:

• Day temp.: room temperature during the day, corresponding to the “Continuous day” program.

• Night temp.: room temperature at night, corresponding to the “Continuous night” program.

• Frost temp.: room temperature to protect the room where the controller is installed from freezing. This setting comes under the “Frost protected” program.

The programs mentioned are explained in paragraph 6.1.

With the aid of the c-Mix, the thermostat can control two groups; both groups can be assigned their own program and control strategy. This is done via: Menu>Settings>System>Central Heating system>Groups “no groups” is the default setting. The option “1&2 separately” can be used to assign each group its own program. The o icon will appear in the standard screen. You can then press the rotary knob/pushbutton to switch between control of group 1 and group 2. If “2 follows 1” is selected, both groups are assigned their own strategy, but group 2 will follow the program for group 1.60

5.5 Setting the control strategy

The thermostat lets you use the room control and/or weather-compensated control strategies in various ways. You can select a control strategy via Menu > Settings > System > Control settings. When implementing these changes, the user level must be set to “Extended mode”. (See para. 5.1) Specicsettingsforweather-compensatedcontrol If you have opted for a weather-compensated control strategy, a number of extra settings are available via Menu > Settings > System > OTC settings. Heating curve:

• Base outside: outside temperature base point

• Baseowtemp:owtemperaturebasepoint

• Climate outside: outside temperature climate point

Curvature: degree of curvature of the heating curve, depending on your central heating system. Selecttherelevanttypeofheaters:underoorheating,radiatorsorconvectors. This will provide more comfort early and late in the year.

The heating curve is based on an outside temperature of 20°C. When the desired room temperature is increased, the heating curve shifts upwards. The degree of increase is determined using the “RT effect” function. i61

• RT effect:factorinuencingtheshiftintheheatingcurve

• Heat limit day: outside temperature above which the central heating is switched off during the day. The day temperature limit is relevant when the desired room temperature is higher than the night temperature that has been set via Menu > Program > Night temp.

Night temperature limit: outside temperature above which the central heating is switched off during the night. The night temperature limit is relevant when the desired room temperature

the same as or lower than the night temperature that has been set via Menu > Program > Night temp.62

Heating curve – an example -5-15 5 15 25 Outside temperature (ºC) Boiler temperature (ºC)

Base point T001032-06-A Climate point Desired room temperature of 15ºC during the night Increased room temperature during the day Desired room temperature of 20ºC during the day

See also see day/night temperature limit 12.4 The settings for the heating curve are highly dependent on the design of the central heating system and the home. This means that no clear advice can be given on this matter. The heating curve can be optimised during use. The heating curve also shifts upwards or downwards when the temperature is increased or decreased.63

5.6 Setting a holiday program

It can be useful to set a holiday program if you are away from home for some time. This ensures a constant temperature in your home for the period you set. You set the temperature yourself. A holiday program automatically takes effect at 0.00 hours on the start date and ends at 0.00 on the end date. The symbol x appears in the display. This program is switched off and removed once the period set has ended. You can set a maximum of 16 holiday programs. You do this via Menu > Program > Holiday prog.:

• Select View to look at the holiday programs set.

• SelectDesired temp. to set the constant temperature.64

You can change a number of settings via the Settings menu. These are summarised here; a more detailed explanation can be found in the Installation and Service manual.

• Language and display settings.

• Calibration: you can calibrate the sensor by positioning an accurate thermometer next to the thermostat.

• Comfort correction: the thermostat takes into account the perceived temperature.

Frost protection: if an external sensor is connected, the outside temperature will be used to switch on the frost protection automatically. If the outside temperature falls below the set value,thepumpwillcontinuetorunandthecentralheatingwaterwillnotgetcolderthan10°C.

• Anti-Legionella(onlyforcaloriers): to prevent legionella growth, you are advised to heat thecalorierupto65°Conceaweek.

• Tap water temperature: set the desired tap water temperature; for boilers with a temperature program where applicable.

• DHW standby: used to indicate when the tap water needs pre-heating. If the tap water is pre- heated, hot water will be available more quickly.

• Digital input: to have the thermostat carry out tasks from an external module, for example during overtime.

• 5differentcontrol strategies based on room control and/or weather-compensated control.

• Speciccentral heating system settings, such as the home's heating and cooling rate.

An RF room sensor is available for the thermostat RF as an option. This sensor replaces the internal thermostat sensor.

6.1 Selecting program

You can select one of the following programs via Program in the main display:

• Clock prog.: the central heating temperature is controlled by the program you have set.

• Day temp.: the temperature remains constant at the day temperature you have set.

• Night temp.: the temperature remains constant at the night temperature you have set.

• Frost temp.: the temperature remains constant at the frost protection temperature you have set. DHW standby is switched off for this program.

• Holiday prog.: the temperature remains constant at the night temperature, whereby the tap water is on standby between 6.00 and 23.00 (which means that you will get hot water more quickly).

6.2 Temporarily changing the temperature

You can (temporarily) switch off a selected clock program or continuous program at any time by setting the temperature manually.

1. Turn button C from the main display to set a new temperature.

2. Press Adjust time if you also want to set an end time for the manually-selected temperature,

and select this time using push-turn button C.

If you do not select an end time and a clock program was active, that clock program will become active again at the next switch point. Manual operation will then be switched off.66

3. Press Adjust date if you also want to set an end date for the manually selected temperature, and

returns to the main menu. Press the Next program button to cancel the manual temperature change.

Once the temperature has reached the desired level in the room where the thermostat has been positioned, thecentralheatingswitchesoff.Thismaybeinconvenientif,forexample,youhaveanopenreorifalotof people are present in that room. Other rooms in the house are also no longer heated in this situation. YoucanswitchonthereplacemodeviatheProgram button so that the other rooms are still heated. This switches off the built-in room sensor in the thermostat. The temperature of the central heating water at that point is then maintained. If it becomes too cold or too hot in the other rooms, you can increase or decrease the room temperature there using push-turn button C on the thermostat. This increases or decreases the central heating water temperature.Youcantthermostatvalvestotheradiatorsinordertoindividuallycontrolthetemperaturesin these rooms.

We advise that you close the radiator valves in the room in which the thermostat has been positioned to prevent the room temperature there becoming too high.

The thermostat switches to weather-compensated control if the outside temperature sensor is used.

You can request operating information about your central heating system, such as the water pressure in the central heating system and various temperatures, via Menu > Information. The information available depends on your central heating unit. The “Basic” and “Normal” modes do not show all information categories which are available. Select More information to make all information available.

8. Problems and solutions

Problem The central heating is coming on too early in the morning. Solution Adjust the Max. pre-heat time setting (see the installation and service manual).The home may well not be up to temperature on time as a result. Problem The home is not warm on time. Solution - Open the radiator valve further when the radiators warm up. - Increase the Max. pre-heat time (see the installation and service manual). - Increase the desired Heating rate by adjusting this to Fastest, for example (see the installation and service manual). For weather-compensated control you have the following options: - Set the radiator thermostat valves correctly. - Adjust the heating curve (see the installation and service manual). - Change the control strategy (see the installation and service manual).). There may also be technical problems with the central heating installa- tion. In that case contact your installer.75

Problem The house is too warm. Solution Weather-compensated control means that no account is taken of the measuredroom temperature. Solve the problem in one of the following ways: - Set the radiator thermostat valves correctly. - Reduce the heating curve (see the installation and service manual). - Change the control strategy (see the installation and service manual). Room control may mean that the heat up rate is too high or that the thermostat is not correctly calibrated. Problem The house does not become warm enough. Solution Weather-compensated control means that no account is taken of the measuredroom temperature. Solve the problem in one of the following ways: - Set the radiator thermostat valves correctly. - Increase the heating curve (see the installation and service manual). - Change the control strategy (see the installation and service manual).76

Problem It takes too long for the tap water to get up to temperature. Solution - Boiler: the DHW standby function may be switched off. In that case the symbol T is shown in the display. Control the DHW standby with the DHW standby setting (see the installation and service manual). - Boiler: the boiler may be heated up too late. Set the tap water temperature using the DHW (see the installation and service manual). Problem Theboilersuppliesnohotwaterorhotwateronlybriey. Solution The DHW standby function T may be switched off. Switch the DHW standby function to Continuous (see paragraph 6.1).77

Problem The boiler starts heating the home or the tap water at night even though the thermostat is set low. Solution - Weather-compensated control (OTC) means that the boiler is controlled led by the outside temperature. This can be prevented by adjusting the Heat limit night or selecting another control strategy. See the installation and service manual. - The boiler can start pre-heating before the following set point. Adjust the Max. pre-heating time setting (see the installation and service manual). The home may well not be up to temperature on time as a result. - The tap water is only heated when the room temperature set is higher than the night temperature. See the installation and service manual for details of how to change the night temperature. Problem The temperature measurement differs from that which I am used to. Solution Correct the temperature measurement via the Calibration setting (see the installation and service manual).78

Problem The display does not function. Solution Thermostat OpenTherm: your boiler may not support OpenTherm Smart Power. Thermostat RF: insert (full) batteries. Problem The backlight for the display does not work. Solution Thermostat OpenTherm: your boiler may not support OpenTherm Smart Power.Inthatcasetbatteriesinthethermostat(seeparagraph3.2).
