Dismounting the clock thermostat
Using a screwdriver, loosen the front panel at the two side
and bottom openings .
Then release the catches on the left and right and remove
the upper part of the housing .
Loosen the plug-in connectors and press the circuit board
carrier together at the top and bottom .
Remove the circuit board carrier through the front.
4. Connection
•The power supply from the thermostat to the boiler is
provided via OpenTherm.
•The two-wire connection (OpenTherm) is not polarised,
i.e. the wires can be connected to the boiler as required.
!Disconnect the boiler from mains supply before connec-
ting the thermostat.
!Faulty connections will damage the device.
!Without interference, the bus line can be extended up to
50 m.
!In order to eliminate the possibility of EMC interference,
always lay the feed of the supply voltage separate from
the mains cables.

Program
In the program menu,
•programs P1 – P3 can be changed
•a new program, or
•a holiday program can be created, or
•a domestic water program, in case of a heating system
using domestic water
•Programs P1–P3 can be set, edited, or deleted.
•A maximum of 24 switching times can be set per pro-
gram, up to a total of 42.
LDuring programming, selected days are shown like , and
unselected days like .
The created programs are automatically sent to the clock
thermostat.

13
Creating a holiday program
In order to create a holiday program and activate it,
slide the controller to "Activation"
After a holiday program has been created via the app, the
clock thermostat receives the following information:
– active/not active
– Start date and end date with time
– Room set temperature during holiday time
– If holiday time is active, the domestic water heating will be
switched off (set temperature 10 °C)

LThe information in this submenu vary depending on the
connected boiler.
With Info, temperature, flame, set flow etc. can be queried.
The functions change, depending on the connected heating
system.

LThe functions in this submenu have to be set by the quali-
ed electrician.
In the settings, language, temperature (comfort, eco, frost),
wall compensation, optimisation, chimney sweep function, etc.

16
1. Setting the wall compensation
If the installation location is unfavourable, temperature
deviations between detected and actual room temperature
might occur. This difference can be corrected by using the wall
compensation.
2. Setting the controller
The clock thermostat can be used – depending on the set
heating – as room-dependent (room temperature dependent)
or weather-dependent (outdoor temperature dependent)
version, or as a relay version.

17
When connected to a modulating heating
•In the room-dependent version, the room set tempera-
ture is used for direct control.
P band (0.5 K–2.5 K) control range
I share (1–20) integral share in minutes:
– Integral share small → quick adjustment of the
control deviation
– Integral share large → slow adjustment of the
control deviation
•In the weather-dependent controller, the ow tempe-
rature is determined by a dened heating curve. The
setting of base point and end point always refers to a
room set temperature of 21 °C.

Changing the heating curve temporarily
In case of an offset of the desired room set temperature, a
corresponding offset for the ow set temperature will be
calculated. The set offset determines by which value the ow
set temperature will be offset per degree from the room set
temperature of 21 °C.
Example
At an outside temperature of – 5 °C, a ow set temperature
of e.g. 50 °C will be calculated for the settings of base point
and end point, in order to reach the room set temperature
(reference temperature) of 21 °C. However, if the desired
room set temperature is at 19 °C, at a set offset of 10 K/°C,
a ow set temperature of
ow set temperature = 50 °C – (21 °C–19 °C) x 10 K/°C =
50 °C – 20 K = 30 °C will be calculated.
Switching off the heating (heating off at)
With weather-dependent control, you can program the
controller so that the heating switches off at a set outdoor
temperature.

20
Setting the room influence
With weather-dependent control, the ow temperature can
be adjusted if there is a large divergence between the room
temperature and the set temperature.
Offset feed temperature = ∆ Tv
Set room inuence = PI
Setpoint value of room temperature = TR set
Actual value of room temperature = TR act
∆ Tv = PI (TR set – TR act)
Example: TR set = 20 °C TR act = 18 °C PI = 3
∆ Tv = 3 x ( 20 °C – 18 °C) = 6 K
→The ow temperature is increased by 6 K.
The higher the selected room inuence, the greater the inu-
ence of the room temperature on the ow temperature.

Behaviour of a PD controller (pulse duration con-
troller)
With adapted heating systems, a PD controller is characte-
rised by its short transient time, minimal overshoot and high
control accuracy.
Behaviour of a hysteresis (on/off) controller
In over or undersized heating systems, a hysteresis controller
is characterised by a minimum switching frequency and low
temperature deviations.
