1. Introduction
The modulating timer thermostat is an OpenTherm timer thermostat with many enhanced functions.
The thermostat is supplied in two versions:
• Thermostat OpenTherm
• Thermostat RF (wireless), with the base station RF transmitter
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.
2. Overview
The thermostat is menu-controlled, which means it is very simple to operate: it only has three buttons.

3. Installation
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.
Do not locate the thermostat too close to heat sources (fireplace, radiator, lamp, candles, direct sunlight etc.), or in places where it may be draughty.
Thermostat RF
The following also apply for the thermostat RF:
- Position the thermostat at least 1 metre from equipment with electromagnetic emissions such as washing machines, Tumble driers, wireless telephones, TVs, computers, microwave ovens, etc.
- Position the thermostat so that it has good reception. Take account of the fact that objects containing metal will affect the reception. These include steel-reinforced concrete, mirrors and windows with a metal coating, insulating films etc.
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. These include mirrors and windows with a metal coating, insulating films etc.
i The signal strength can be viewed via Menu > Information.
3.2 Installation and connection
The following must be done before you install and connect the thermostat:
- Adjust the boiler so that it can be connected to an OpenTherm thermostat.
• Turn off the boiler.
Consult the boiler documentation for this process.
Do this as follows:
-
Open the housing by pulling the front and the base plate apart.
-
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.
-
Connect the thermostat to the boiler OpenTherm connection and the thermostat OT connection. OpenTherm is polarity insensitive; you may therefore swap the wires.

- 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.

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.
• The sensor must be positioned at least 2.5 metres above ground level.
- Do not install the outside sensor near windows, doors, ventilation grills, extractors, etc.
Consult the documentation for your boiler for information on connecting an outside temperature sensor.
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.
EN
4. Prior to first use
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.
- Select the desired language if applicable by turning button C and then push button C to confirm.
- 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.
4.2 Default setting
Room control
The thermostat is set to room control by default. This means that the flow temperature of the 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 water flow temperature together with the outside temperature. The heating curve must be chosen so that the least favourable room can be efficiently heated even when the outside temperature is very low.
See paragraph 5.5 for further information about weather-compensated control.
Clock program
The default clock program sets the temperature each day as follows:
• 06:00 – 19:00: 20°C
• 19:00 – 23:00: 21°C
- 23:00 - 06:00: 15^ C +
You can of course adapt the clock programs to your own requirements. See Chapter 5.
5. Setting
5.1 Three usage modes
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.
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.
An example of an overview is shown below:
| Time | D. TU. WE. TH. FR. SA. SU. | ||||||||
| 7:00 20°C | C | 20°C | 20°C | 20°C | 20°C | ||||
| 9:00 15°C | C | 15°C | 15°C | 15°C | 20°C | 20°C | |||
| 11:00 | |||||||||
| 13:00 | |||||||||
| 15:00 15°C | |||||||||
| 17:00 | |||||||||
| 19:00 21°C | C | 21°C | 21°C | 21°C | 21°C | ||||
| 21:00 21°C | |||||||||
| 23:00 15°C | C | 15°C | 15°C | 15°C | 15°C | ||||
| 0:00 15°C | C | 15°C | |||||||

Restoring the default settings
Select Menu > Program > Clock prog. > Factory settings to restore the settings for the default clock program.
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.
i The programs mentioned are explained in paragraph 6.1.
5.4 Group control
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 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.
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)
Specific settings for weather-compensated control
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
- Base flowtemp: flow temperature base point
• Climate outside: outside temperature climate point
• Climate flowtemp: flow temperature climate point - Curvature: degree of curvature of the heating curve, depending on your central heating system. Select the relevant type of heaters: underfloor heating, radiators or convectors.
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.
• RT effect: factor influencing the shift in the heating curve
- 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 is the same as or lower than the night temperature that has been set via Menu > Program > Night temp.
Heating curve – an example
line
| Outside temperature (°C) | Increased room temperature during the day | Desired room temperature of 20°C during the day | Desired room temperature of 15°C during the night | | ------------------------ | ----------------------------------------- | ------------------------------------------------- | ------------------------------------------------- | | -5 | 90 | 85 | 60 | | 0 | 80 | 75 | 45 | | 5 | 70 | 65 | 35 | | 15 | 60 | 55 | 25 | | 25 | 50 | 45 | 15 | | >25 | ~20 | ~15 | ~5 |① 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.
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 □ 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.
- Select Change to change or remove programs.
- Select Enter to add a new program.
- Select Desired temp. to set the constant temperature.
5.7 Other settings
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, the pump will continue to run and the central heating water will not get colder than 10^ .
- Anti-Legionella (only for calorifiers): to prevent legionella growth, you are advised to heat the calorifier up to 65°C once a week.
- 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.
• 5 different control strategies based on room control and/or weather-compensated control.
• Specific central 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.
- Additional functions, depending on the boiler (from thermostat v20): Adjust boiler "Parameters", "Restore param.", "Reset service" and "Start detection".
6. Using the thermostat
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.
- Turn button C from the main display to set a new temperature.
- 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.
- Press Adjust date if you also want to set an end date for the manually selected temperature, and select this time using push-turn button C.
- Press button C to return to the main menu or wait five seconds until the thermostat automatically returns to the main menu.
Press the Next program button to cancel the manual temperature change.
EN
6.3 Fireplace mode
Once the temperature has reached the desired level in the room where the thermostat has been positioned, the central heating switches off. This may be inconvenient if, for example, you have an open fire or if a lot of people are present in that room. Other rooms in the house are also no longer heated in this situation.
You can switch on the fireplace mode via the Program 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. You can fit thermostat valves to the radiators in order to individually control the temperatures in these rooms.
The fireplace mode should only be activated if the thermostat uses the room temperature to control the temperature.
① 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.
6.4 Information
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.
