Either floor temperature sensor or external room temperature sensor can be used.
Dew point monitoring is essential to prevent condensation on the chilled ceiling
(cooling with fan disabled, P52). It helps avoid associated damage to the building.
A dew point sensor with a potential-free contact is connected to multifunctional
input X1 or X2. If there is condensation, the cooling valve is fully closed until no
more condensation is detected, and the cooling output is disabled temporarily.
The alarm icon flashes during temporary override and the fault "Condensation
in room" is sent using the bus.
The input must be configured accordingly (P38, P40). See section 3.9.
The "Screen lock" function is enabled and disabled only by using P14. There are
three options:
·
Unlock
·
Locked (all adjustments are locked but can be viewed)
·
Setpoint (note: only setpoint adjustment is not locked)
The "Buzzer" function provides audio feedback when you touch the operating icons
on the thermostat (see page 9).
Enable or disable the "Buzzer" function via P16.
