Safety
The room thermostat controls thermal actuators connected in
a room-by-room temperature control system directly or via a
connection unit. The unit
• is a fi xed installation,
• measures the actual temperature (room temperature),
• can be used to set the target temperature (comfort
temperature),
• can be used to control the actual temperature by activating
actuators in heating/cooling operation in a predetermined
zone.
Every other use, modifi cation and conversion is expressly
forbidden and leads to dangers the manufacturer cannot be
held liable for.
All safety notes in these instructions must be observed in order
to avoid accidents with injury or property damage.
• Only an authorized electrician may open the device. It may
only be opened in de-energised state.
• Always disconnect from the mains network and secure
against unintended activation before opening.
• Only use the device if it is in perfect working condition state.
• Observe the performance limits of the device and the
environmental conditions.

operation" changes to the stored temperature. The
target temperature can be changed with the dial,
independently of the active operating mode. You can
fi nd more information in the section Lifestyle functions
menu.

Comfort and protection functions
5 Comfort and protection functions
5.1 Comfort functions
In order to increase user comfort, the room thermostat includes
functions for controlling the comfort temperature.
5.1.1 Heating/cooling change-over
This function switches the entire installation between heating
and cooling using an external signal.
5.1.2 Restricted Mode
The restricted mode only allows the target temperature to be
changed.
Activate mode
Activation is as follows:
Activate parameter 032 in the Service menu (value: 1).
The operating mode active before restarting is continued
for restricted operation.
De-energise the device.
Apply voltage again.
The restricted mode is activated.
Deactivate mode
De-energise the device.
Hold down the dial and apply voltage again until the software
version is shown on the display and disappears again.
In the Service menu, deactivate parameter 032 (value: 0).
The device is permanently in standard operation.

20
Comfort and protection functions
Temporarily deactivate mode
The restricted mode can be temporarily deactivated to use or
activate disabled functions of the device during this time. After
a voltage interruption of the device, the restricted mode is
reactivated.
De-energise the device.
Hold down the dial and apply voltage again until the software
version is shown on the display and disappears again.
The device is temporarily in standard operation until the next
power interruption occurs.
5.2 Protection functions
The room thermostat is equipped with protection functions for
avoiding damage to the overall installation.
5.2.1 Valve protection function
In periods without valve activation (e. g. outside the heating
period), all valves are opened cyclically. This avoids a clogging
of the valves (parameters 190 and 191).
5.2.2 Antifreeze protection
Independent from the operating mode, the room thermostat
is equipped with an antifreeze function (parameter 161).
When the temperature falls below the antifreeze protection
temperature, all connected actuators are activated and the
valves are opened.
