P20 Key lock mode
With active password, select the number and type of locked keys.
1 All keys locked
2 Key lock applied to set-point editing, changing from summer to winter mode and vice versa, and changing from
comfort set-point to economy set-point and vice versa.
3 Key lock applied to changing from summer to winter mode and vice versa, and changing from comfort set-point to
economy set-point and vice versa.
P21-P22 Adjustment differential
The differential value that can be set is between 0.3°C and 5.0°C, or standard Std (default = Std).
P33 Minimum sensor threshold triggered (winter mode)
This setting is only effective if
P11
= 2 or
P11
= 3 or
P12
= 7 or
P12
= 8
When the supply temperature falls below the set value, the thermostat stops ventilation.
P34 Minimum sensor threshold triggered (summer mode)
This setting is only effective if
P11
= 2 or
P11
= 3 or
P12
= 7 or
P12
= 8
When the supply temperature rises above the set value, the thermostat stops ventilation.
P36 Lower change-over threshold
This setting is only effective if
P11
= 4 or
P12
= 9
When the supply temperature drops below the set value, the thermostat automatically switches from heating to cooling.
P37 Upper change-over threshold
This setting is only effective if
P11
= 4 or
P12
= 9
When the supply temperature rises above the set value, the thermostat automatically switches from cooling to heating.
P38 Dead zone interval
When the thermostat operates in
AUTOMATIC
with subordinated ventilation in the dead zone, the fan is off; with continuous
ventilation, minimum speed remains enabled.
P50 Remote actuator selection
Selection of the remote actuator model that CH133AR2 will be connected to:
176
: CH176D (equipped with remote temperature sensor and 0..10V output)
172
: CH172D (relay only)
