Fig. 12 Example of heating program
If the FR 100 is connected to the heating appliance via the analogue connection (1-2-4 interface), only the heating program, the parameters for central heating and the controller-specific settings (e.g. Time) are active. DHW, solar and system-specific settings (e.g. System info) are not available. In this case, DHW can be switched directly via the heating appliance.
Once the controller is set to your personal preferences, you hardly need the menus for “everyday use”. Nevertheless, it is useful to be familiar with basic navigation through the menus.
Therefore, you should read the whole of the following sections 5.1 and 5.2 below and adjust a heating or DHW program to your own requirements as described in chapter 5.2.2.
Why not take the trouble – it will be worth your while! The procedure for changing a switching point will illustrate everything you need to know about navigating through the menus and entering settings. You can then make all other settings in
the same way with the aid of the information in chapters 6 and 8.
The description of the menus reflects the arrangement of the menu points in the heating controller. The tables in chapters 6.1, 7 and 8.1 show the entire menu structure. They also provide details of the setting ranges and factory settings for all adjustable parameters. More information on the menu points can be found in sections 6.2 to 6.5 for the user level, and sections 8.2 to 8.8 for the contractor level.
The description of a menu points starts with its menu path. That shows you how to reach the menu point concerned by navigating through the menus. The individual menu levels are separated by symbol >, e.g. holiday > start.
Some menu points are dependent on others. In such cases, a page reference directs you to a description of the menu point on which it depends. Make use of such page references to other menu points. They will help you to understand associated functions.
The controller provides the option of setting the required room temperature for the operating mode concerned.
5.1 Heating and DHW programs
5.1.1 General
The programs for heating and DHW enable you to achieve maximum energy savings while still enjoying optimum comfort in terms of room temperature and availability of hot water. That is achieved, for instance, by deactivating DHW heating at times when nobody requires hot water.
5.1.2 Weekly programs
All time programs are set up to repeat every seven days. In the program memory you can store 6 switching times per day in each program, i.e. a total of up to 42 switching times.
To simplify programming, you can set switching times for groups of days as well as for individual days.
The following groups of days are offered:
• All days
• Mon - Fri
- Sat + Sun
If, for example, you change and save a switching time for menu point Mon - Fri, that change is simultaneously applied to every day from
Monday to Friday.
5.1.3 Structure of programs
Programs for heating and DHW are always structured in the same way. Up to six switching points (switching times) can be specified. A change of operating mode is specified for each switching time. The specified operating mode applies until changed by the next switching time.
Heating programs
Heating programs control central heating operation. There are three modes for heating operation:
- Comfort
- Economy
- Frost (frost protection)
-or-
Individual temperature levels:
• 5 °C to 30 °C in 1 °C increments.
For each of these operating modes, there is a set room temperature stored in the FR 100 / FR 110 heating controller ( chapter 5.4.1, page 29).
There are a total of six program spaces (A to F) available in the memory for heating programs. Each heating program contains the switching times for one week (weekly program). You can activate one heating program at a time.
Having several stored heating programs simplifies the change from one heating program to another, e.g. if your job involves periods when you work different shifts (night shift/day shift), or for holiday periods.
DHW programs
Domestic hot water programs operate differently according to the type of DHW system:
- With combi boilers (boilers which produce hot water instantaneously on demand), the DHW program switches between the following operating modes:
- On: if the eco button on the heating appliance is not lit, hot water is available very quickly on demand (comfort mode).
- Off: the built-in plate heat exchanger in the heating appliance is not kept constantly hot (eco mode); as a result energy is saved. In eco mode, the hot tap has to be run for a short while before the water becomes hot.
- If the DHW cylinder and FR 100 are directly connected to the heating appliance, the DHW program switches between the following operating modes:
- On: Cylinder heating enabled (temperature in accordance with setting on heating appliance).
- Off: Cylinder heating blocked.
- With appliances connected to a DHW cylinder and FR 110, the DHW program specifies the required water temperature (set temperature).
- If the temperature measured in the DHW cylinder is below the set temperature, the cylinder is reheated.
- Once the set temperature is reached (or exceeded), cylinder reheating is stopped.
If the DHW program changes from a higher to a lower temperature, the water in the cylinder will not immediately cool to the lower temperature, i.e. water at a higher temperature will continue to be available for some time. However, the cylinder will not be reheated until the temperature falls below the new set temperature.
The DHW circulation program specifies when a connected DHW circulation pump for domestic hot water runs.
5.2 Setting programs
The functions of the controls and the meanings of the symbols on the display are explained on pages 2 and 3.
5.2.1 Display views and menu navigation
The user interface of the FR 100 / FR 110 room temperature-dependent heating controller is implemented as a so-called "menu". Within that menu, the various functions are arranged in a hierarchical structure. For greater clarity, the menu is subdivided into three sections (MAIN MENU, INFO, INSTALLER SETTINGS). Each section can be accessed by its own button. The entire menu structure is shown in tabular form in chapters 6.1, 7 and 8.1.
To navigate through the menu:
- Press menu to open MAIN MENU. From any point within the MAIN MENU, press to go back to the standard display.
- Press info to open the INFO menu. From any point within the INFO menu, press info to go back to the standard display.
- Hold down for at least 3 seconds to open the INSTALLER SETTINGS menu. From any point within the INSTALLER SETTINGS menu, press to go back to the standard display.
- The selected menu point/parameter is displayed in inverse, i.e. white on black.
- Arrows in the left margin indicate that there is more information than can be shown on the display at once. It can be viewed with
- opens the submenu associated with the selected menu point/parameter or activates editing mode for the parameter (the parameter setting starts flashing).
- A flashing parameter setting (e.g. switching time or operating mode)

- remains unchanged if any other key apart from is pressed.
- To return to the next menu up from a submenu:
- Highlight menu point and Back confirm with or
- press
5.2.2 Setting and changing switching times and operating modes
The way in which switching times and operating modes are set is always the same; the only differences are due to the various operating modes for each switching point.
The unit is supplied with programs for heating and DHW already stored. It may also be that your heating installer has adjusted the programs to suit your requirements (lifestyle).
Changing (moving or deleting) a single switching point
The example below shows all the steps required to change a switching point in a heating program. If, instead, you want to change a switching point in a DHW program, open the DHW program concerned (menu path: Domestic hot water > DHW programme > Edit) and change the switching point in the same way.
▶ Open flap.
The standard display continues to be shown.
▶ Press
The display lighting switches on and the main menu is displayed.

▶ You can now:
- change more switching times and operating modes in the same way, or
- finish programming and return to the standard display by pressing menu
Using groups of days when programming
In many cases, you may want to programme the same switching times for several days of the week, say for all working days. Equally, you may also want a different program for just one of those days.
Using the groups of days when programming enables you to complete the process in only a few steps.
For a group of days, e.g. Mon - Fri, programme the switching times and operating modes that should apply to the majority of the days in this group of days.
▶ Then change the switching times for the days that are different.
Copying pre-saved heating programs
There are eight pre-saved heating programs permanently stored in the heating controller memory. They cannot be directly applied to a heating circuit.
To be able to use the pre-saved heating programs, you must copy them to one of the memory locations for heating programs (A to C), where you can also adapt them if necessary ( chapter 5.2.2).
You can also copy any of the programs A to C or D to F to another location as a template.

6.3 DHW program
Main menu: Domestic hot water
The DHW program is only available for FR 100 with code 1 on a heating appliance with BUS-enabled Heatronic 3 and for FR 110 ( chapter 4 on page 18).
Set the DHW temperature controller on the heating appliance to the maximum required DHW temperature.
For FR 110: If a DHW cylinder is connected to the IPM downstream of the low loss header, turn the flow temperature controller on the heating appliance fully clockwise.
If the DHW program changes from a higher to a lower temperature, the water in the cylinder will not immediately cool to the lower temperature, i.e. water at a higher temperature will continue to be available for some time. However, the cylinder will not be reheated until the temperature falls below the new set temperature.
You can use this menu point either to ... ... Activate your individual DHW program (Separate programmes). Recommended for systems with several heating circuits.
- or -
... Link the DHW program to your heating program (As heating programme). That is useful if you frequently switch between different heating programs. The DHW program is then automatically adapted to suit.
Recommended for systems with one heating circuit.
- As heating programme (automatic mode together with the heating program):
With combi boiler:
DHW On as long as the heating circuit is in
Comfort mode and for 1 hour afterwards (run-on time).
Otherwise DHW Off.
With FR 100 and DHW cylinder at the heating appliance:
DHW On as long as the heating circuit is in
Comfort mode or changes to heating mode within the next hour.
Otherwise DHW Off.
With FR 110 and DHW cylinder:
1 hour before the heating circuit enters
Comfort mode, cylinder heating to the selected DHW temperature starts
(Cylinder temp at heating level Comf. ^1) ).
This setting remains active for as long as the heating circuit stays in Comfort ✿ mode.
If the heating circuit is in Economy
mode, then the cylinder will be held at the temperature selected under Cylinder temp at heating level Eco ^1) .
1) Set DHW temperature → chapter 6.3.5 on page 47
If the heating circuit is in Frost mode, then frost protection is also applied to the cylinder (15 °C fixed value).
With DHW circulation pump for DHW cylinders (only FR 110):
DHW circulation pump On and DHW circulation pump starts according to setting ( chapter 6.3.5 on page 47) if one of the heating circuits is in Comfort ✿ mode.
- Separate programmes (independent time programs):
Automatic changeover between DHW On ^2) / Off ^2) or different DHW temperatures ^3) and DHW circulation pump On / Off according to the stored programs.

6.3.6 Thermal disinfection of hot water (with DHW cylinder only)
Menu: Domestic hot water > Thermal disinfection
This menu is only active if your domestic hot water is provided by a DHW cylinder. We recommend that you carry out thermal disinfection at regular intervals. For larger DHW systems, there may be a legal requirement for thermal disinfection.
If you have a combi boiler, please refer to the guidance in the boiler documentation.
NOTICE: Risk of scalding!
Hot water can lead to severe scalding.
▶ Only carry out thermal disinfection at times when the system is not normally in use.
▶ Inform occupants of the building of the danger of scalding and always monitor the thermal disinfection process.
- Operating mode:
- Auto: Thermal disinfection starts automatically according to the set starting conditions. Thermal disinfection can be switched on and cancelled manually.
- Manual: Thermal disinfection can be started from Operating status.
- Operating status:
- Not running: No thermal disinfection at present. Once-only thermal disinfection can be started by selecting Start now.
- Running: Thermal disinfection in progress. Thermal disinfection can be terminated by selecting Stop.
If Solar sys option E Thermal disinfection is switched on ( chapter 8.4 on page 60) and thermal disinfection is terminated by selecting Stop, a fault is indicated for 5 minutes if the disinfection temperature in the solar cylinder has not been reached (fault 54 chapter 9.1 from page 65).
- Time: Start time for automatic thermal disinfection.
- Time interval: Period until next start time for automatic thermal disinfection.
If you want to use automatic thermal disinfection (e.g. once a week), proceed as follows:
▶ Set the required time interval (e.g. 7d, i.e. 7 days).
▶ Set the required start time (e.g. 22:00).
▶ Set the operating mode to Auto on the day on which you want thermal disinfection to take place.
For menu structure and setting ranges → page 34.
6.4 General settings
6.4.1 Time and Date
Menu: General settings > Time and date
Use this menu if you want to correct the date and time.

▶ Switch automatic summer/wintertime changeover off.
- Time adjustment: Sets the adjustment factor for the time. The adjustment is carried out once a week.
Example:
- The time is out by approximately - 3 minutes a year
-- 3 minutes a year is equal to - 180 seconds a year
- 1 year = 52 weeks
-- 180 seconds ÷ 52 weeks
= -3.46 seconds a week

6.5 Solar settings
Main menu: Solar
Use this menu if you want to limit the cylinder temperature or optimise the set DHW and flow temperatures based on the available solar energy in your geographical region.
Limiting cylinder temperature
In order to store as much solar energy as possible, a high cylinder temperature is required.
Limiting the cylinder temperature prevents overheating of the domestic hot water. The temperature setting is transmitted by the ISM module during commissioning.
WARNING: Risk of scalding! If the cylinder temperature is higher than 60 °C.
▶ If the cylinder temperature limit is set to > 60 °C, install a thermostatic DHW mixer or the DHW comfort assembly (WWKG, accessories → Fig. 4 on page 13) in the DHW line.
▶ Set the DHW mixer unit to 60 °C max.
- T2: Max. solar cylinder temperature: Cylinder temperature > 60 °C in DHW cylinders only if outlet temperature is limited by thermostatic DHW mixer.
For menu structure and setting ranges
→ page 36.
Solar optimisation
In order to use as much solar energy as possible, the FR 110 heating controller can estimate the expected solar yield over the course of a day and take it into account when controlling the DHW. The heating appliance will then not be required to produce as much heat and will use less gas.
For more information for heating contractors
→ chapter 8.5.3 on page 62
- Optimizing influence DHW: Maximum reduction of set DHW temperature by effect of solar thermal system.
Example:
- Set DHW temperature = 60 °C
- Optimizing influence DHW = 15 K
- Set DHW temperature for heating appliance = 60 °C - 15 K
- Provided there is sufficient solar output available, the maximum reduction is set and the heating appliance heats the DHW to 45 °C, with the remaining 15 K being provided by the solar contribution.
Optimizing influence DHW does not start until a calibration phase of at least 30 days has been completed after commissioning of the solar thermal system. In that period, the FR 110 heating controller “learns” what level of solar yield is possible.

8.2 Configuring the heating system
Contractor level: System configuration
An example system is shown in chapter 2.5 on page 12. Other examples can be found in the instructions for the IPM or the technical guides.
Use this menu if you want to configure the system automatically or manually, e.g. when commissioning or making changes to the system.
- Connection type for the setting of the type of connection with the Heatronic 3 (only FR 100).
- Start automatic system configuration for starting automatic configuration.
- Domestic hot water configuration for the manual configuration of the DHW system (only for FR 100 with code 1 or FR 110).
- CH system configuration for the configuration of the assigned heating circuit.
- DHW circulation pump: This menu point is only active if a DHW circulation pump has been installed in the DHW system (only for FR 110).
- Identification CH circuit for the selection of the associated heating circuit (1 ... 10 - only FR 100)
When commissioning a heating system, proceed as follows:
▶ Code all BUS subscribers in accordance with their function (e.g. IPM 1 for heating circuit 1 etc.).
▶ Start automatic configuration.
▶ Check the other menu points under System configuration and, if necessary, adjust manually to suit the current system.
The heating system's solar thermal system must be configured manually ( chapter 8.4, page 60). Automatic configuration of the heating system does not configure the solar thermal system.
For menu structure and setting ranges → page 55.
8.3 Parameters for heating
Contractor level: Heating parameters
Set the flow temperature control on the heating appliance to the maximum required flow temperature.
Use this menu if you want to set the parameters for the associated heating circuit.
- Calibrate room temperature sensor:
- Fit a suitable precision instrument near FR 100. or FR 110. The precision instrument must not transfer any heat to the FR 100 or FR 110.
- Keep away from heat sources such as sunlight, body heat, etc. for 1 hour.
- Adjust the displayed room temperature correction value.
- Adjustment factor I
The Adjustment factor I is the rate at which a constant room temperature control deviation is corrected.
- ≤ 40 %: Set a lower factor to achieve minimal room temperature overshoot by more gradual correction.
- ≥ 40 %: Set a higher factor to achieve faster correction by a greater room temperature overshoot.
- Amplification factor V:
Subject to changes in room temperature, the Amplification factor V influences the heat demand.
- ≤ 80 %: Set a lower factor to reduce the influence on the heat demand. The selected room temperature is reached more slowly with only minimal overshoot.
- ≥ 80 %: Set a higher factor to increase the influence on the heat demand. The
selected room temperature is reached quickly with a tendency to overshoot.
- Heat-up optimisation:
- No: The heating program contains only switching times for the assigned heating circuit.
- Yes: The heating program contains times for the required room temperatures. The controller shifts the switching times for the heating automatically. When doing so, it is guided by the heating times required on previous days. In that way the controller is able to take account of seasonal outside temperature fluctuations.
While the modes Economy © / Frost ✉ are active, the conditions must remain constant for the lead room:
Keep the same doors closed.
Keep windows closed wherever possible. Heat the same rooms.
Do not adjust or cover radiators or valves.
→ More information can be found in chapter 10 on page 73.
If those conditions can not be maintained for several days:
▶ Operate the controller without heat-up optimisation.
• Maximum CH flow temperature:
Set Maximum CH flow temperature to suit the associated heating circuit.
- Mixer running time:
Set the Mixer running time to suit the runtime of the mixer servomotor used for the associated heating circuit.
8.4 Configuring the solar thermal system
The heating system's solar thermal system has to be configured manually. Automatic configuration of the heating system ( chapter 8.2, page 58) does not configure the solar thermal system.

10 Energy saving tips
- The temperature in the lead room (where the controller is fitted) acts as a guide for the heating circuit to which the controller is assigned. Therefore, set the output of the radiators inside the lead room as low as possible:
- For manual valves via preselection.
-
With fully opened thermostatic valves via the return fitting. If the thermostatic valves in the lead room are not fully open, they may reduce the heat supply even though the controller requests heat.
-
Regulate the temperature in adjacent rooms via thermostatic valves.
- External heat in the lead room (e.g. solar radiation, stove etc.) can result in too little heating in adjacent rooms (the heating system remains cold).
-
Make effective use of the temperature levels and switching times by setting them to suit the preferences of the occupants.
-
Comfort = For a comfortable living environment
- Economy = For an active living environment
-
Frost = For when away or asleep
-
Much energy can be saved by reducing the room temperature via economy phases. Reducing the room temperature by 1 K (°C) enables up to 5% energy to be saved. It is not recommended to let the room temperature of heated rooms fall below +15 °C during the daytime, otherwise the cooled-down walls continue to radiate cold and the room temperature rises higher, leading to higher energy consumption than if an even heat supply is applied.
- Good thermal insulation of the building: the set temperature for Economy is never
reached. Nevertheless energy is being saved as the heating system stays off. In that case set the switching point for Economy to an earlier time.
- Don't keep windows slightly open for ventilation. This leads to a constant extraction of heat from the room without noticeably improving the ambient air in the room.
- Vent briefly but intensively (open window fully).
- When ventilating, turn off the thermostatic valve or set the operating mode selector to Frost.
- Make effective use of the temperature levels and switching times for the domestic hot water by setting them to suit the preferences of the occupants.
If heat-up optimisation is switched on:
- To make best use of heat-up optimisation, set the times for heating up to the temperature levels for Economy or Comfort as late as possible.
- The heat-up optimisation function learns the conditions in the lead room chapter 8.3 on page 59.
The first time heat-up optimisation is used, there may be significant temperature differences. During the initial learning phase, do not change the setting before heat-up is complete. After a few days, the learning process will have advanced and the control accuracy will improve.
- Set the temperature for Economy or Frost as low as possible.
- During Economy or Frost the lead room conditions must remain constantly the same → chapter 8.3 on page 59.
If the conditions change, it can take several days for heat-up optimisation to adapt to the new conditions.
74 | Energy saving tips
- If the home is not heated for an extended period, e.g. over the weekend, the rooms may cool down to such an extent that the heating appliance cannot bring them up to the required temperature by the specified time (start time for heating appliance up to 6 hours before the set time for Economy or Comfort). In that case, bring the time forward by an appropriate amount.
- Only charge the DHW cylinder outside the heat-up period, e.g. 30 minutes after the heating start time.
- If the radiators become unpleasantly hot, the maximum flow temperature should be reduced accordingly on the heating appliance.
Solar optimisation
Activate the Optimizing influence DHW on the FR 110 by setting a figure of between 1 K and 20 K → chapter 6.5 on page 50. If the influence of the Optimizing influence DHW is too great, reduce the setting step by step.
