Room temperature
Setting heating circuit time program
Observe the following 3 points if you want to activate space heating.
1. Heating rmust be selected for the heating circuit.
2. Normal room temperature
(for day) ts and reduced room temperature (for
night) tm can be selected for the heating circuit (see
below).
3. When your heating circuit operates with normal or
reduced room temperature depends on the programmed
times (four possible time cycles) for the respective day.
If no time cycles are selected, space heating will be
active for the whole day at reduced room temperature.
If one or more time cycles are selected, space heating
will be active for those times with normal room
temperature.
For changing programmed times, see below.
Setting a normal room temperature
Set the desired temperature for the normal room
temperature with rotary selector ts.
Setting a reduced room temperature
Press the following keys:
1. tm for reduced room temperature;the currently set
temperature will flash.
2. /for the desired value.
3. as confirmation; the temperature no longer flashes
and is now saved.
Setting switching times (timer program)
4 time cycles:
For space heating, up to four changes between normal and
reduced room temperature can be programmed.
At the factory, time cycle 1 from 06:00 to 22:00 h is set
for every weekday i.e. during that time, all rooms are
heated to the normal room temperature.
You can select identical time programs for all weekdays or
individual programs for each weekday.
When setting time programs please note that your heating
system requires some time to heat the rooms to the desired
temperature.

Further settings
Changing heating characteristics (continued)
Heating curves represent the relationship between the outside temperature and the flow temperature. To put it simply: the
lower the outside temperature, the higher the supply temperature.
The illustrated heating curves apply subject to the following settings:
Shift = 0
Different level settings shift the curve parallel in a vertical direction.
Normal room temperature = approximately 20ºC / 68ºF.
In the factory, the following settings are made: slope = 1.4, shift = 0.
Generally, the heating curve lies:
In range Afor underfloor heating systems
In range Bfor low temperature heating systems
In range Cfor heating systems with boiler water
temperatures above 75ºC / 167ºF
Examples
Well insulated home in sheltered position (with radiator
heating system): Slope = 1.2
Home in exposed position or with an older heating system
(with radiator heating system): Slope = 1.6

Repairs / Energy saving tips
Cleaning
All devices may be cleaned with a commercially available domestic cleaning agent (non-scouring).
Inspection and maintenance
Regular maintenance ensures trouble-free, energy-efficient and environmentally responsible heating operation. We strongly
advise you to arrange an inspection and maintenance contract with your local heating contractor.
Energy saving tips
Not only will you benefit from the advantages of a modern heating system, but you can also save energy by the way you
operate your system.
For this, the following measures will help you:
Correct ventilation:
Briefly open windows Afully, and at the same time close
thermostatic radiator valves B.
Do not overheat:
Endeavour to achieve a room temperature of 20ºC; every
degree of room temperature reduction saves up to 6% of
your heating bills.
Close roller shutters (where installed) at dusk.
Set thermostatic radiator valves Bcorrectly.
Do not cover radiators Cor thermostatic radiator
valves B.
Make full use of the setting options offered by control
unit D, e.g. normal room temperature alternating with
reduced room temperature.
