Expert electricians only may open this device in due compliance with the
wiring diagram shown in the housing cover / on the housing / represented in
the corresponding operating instructions. All expert electricians charged
with the execution of such works must comply with the relevant safety regu-
lations currently operative and in force. Caution: The operation of the con-
troller in the vicinity of other devices that do not comply with the EMC direc-
tives may affect its functions. The company charged with the installation of
the device must, after the completion of the installation works, instruct the
user of the control system into its functions and in how to operate it correctly.
These operating instructions must be kept at a place that can be accessed
freely by the operating and/or servicing personnel in charge.
1. Safety information

5
The controller described in these instructions is provided for flush installa-
tion and has been specially devised for the time-dependent control of the
temperatures in individual rooms or of the temperatures produced by elec-
tric or warm-water heating systems (systems with normally closed valve
actuators). The device can be used as floor or as room temperature controller
with additional floor temperature controller function. Operation in emergency
mode is triggered if the internal or external sensor is defective. The same
applies if no sensor has been connected when using the device as room
temperature controller with additional floor monitoring function and also
when using it as floor temperature controller. An error message appears on
the display and an indicator lamp starts blinking red to indicate this condi-
tion. During operation in emergency mode a fixed 30% duty cycle is being
maintained to prevent the related room from cooling down thoroughly and
protect it against frost damage. The activation time divides into a 3-minute
ACTIVE and a 7-minute OFF time.
2. Application / functional description / emergency operation

6
The device is equipped with 4 touch keys, all of which have been marked by
the symbol . The functions allocated to them may vary in dependence on
the operation requirements. The related function is being indicated on the
display which exists above the corresponding keys. A special protective
function helps prevent an inadvertent activation of the touch keys. This
function is activated 20 seconds after any of the touch keys has last been
activated. Actuating any of the touch keys deactivates this function again for
2 seconds.

If no key has been activated within a period of approx. 5 seconds, the
system returns to normal control mode again. The changed temperature
value is being taken over and imported. The adjusted set temperature con-
tinues to be effective until the moment the operating mode is changed, no
matter if changing manually or automatically after triggering by the switch
clock.

Actuating the touch key “Mode” allows to change the operating mode
in the order shown below:
– Automatic mode (in compliance with the related weekday mode settings)
– Comfort mode, permanently
– ECO mode, permanently
– Operating mode “OFF”
In “OFF” mode, the controller activates the heating when underrunning a
temperature level of approx. 5°C and deactivates the operations when
exceeding a temperature level of approx. 6°C. This antifreezing function
helps prevent rooms from cooling down thoroughly and protects against the
occurrence of frost damage.
