The thermostat is forced into Protection when the window is open. The contact can
be connected to multifunctional input S1/X1/X2. Set P38/P40 to 3. User operations
are ineffective when the window contact is active.
The function is also available via the Modbus signal "Window contact".
Use only one input source, either local input S1/X1/X2 or Modbus. User operations
are ineffective when the window contact is active, or "Window contact" is sent via
Modbus.
The operating mode can be changed to Comfort or Economy based on room
occupancy (room occupied or unoccupied, via presence detector or keycard).
For details, see Hotel keycard/Presence detector [➙ 28].
4.3 Room temperature setpoint
4.3.1 Description
The factory setting for the Comfort basic setpoint is 21 °C and can be changed in
the thermostat’s EEPROM via P08 or via Modbus with communication object
"Comfort basic setpoint". The last command is active.
The Comfort setpoint can be adjusted via the +/- buttons or Modbus from a remote
device such as a touch panel or room operator unit, etc. The last command is
active.
When "Temporary comfort setpoint" is enabled via P69, the Comfort setpoint
adjusted via the + / - buttons or via Modbus is set back to the Comfort basic
setpoint stored in P08 only when the operating mode is changed.
For energy saving purposes, the setpoint setting range can be limited to minimum
(P09) and maximum (P10).
● If the minimum limit P09 is set lower than the maximum limit P10, both heating
and cooling can be adjusted between these 2 limits.
● For heating or cooling applications (e.g. 2-stage):
– The setting range in cooling mode is P09…35 °C in place of 5…35 °C
– The setting range in heating mode is 5…P10 °C in place of 5…35 °C
● For heating and cooling applications (e.g. 4-pipe):
– The cooling and heating setpoint can be adjusted
– The setting range in cooling mode is P09…35 °C in place of 5…35 °C
– The setting range in heating mode is 5…P10 °C in place of 5…35 °C
