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, parameter P52). It helps avoid associated damage to
the building.
A dew point sensor with a potential-free contact is connected to multifunctional
input X1, X2 or D1. If there is condensation, the cooling valve is fully closed until no
more condensation is detected, and the cooling output is disabled temporarily.
The condensation symbol “
” is displayed during temporary override and the fault
“Condensation in room” will be sent via bus.
The input must be commissioned accordingly (P38, P40, P42).
See section 3.9 “Multifunctional input”.
If the “Button
lock” function is enabled by parameter P14, the buttons will be locked
or unlocked by pressing the right button for 3 seconds.
If “Auto lock” is configured, the thermostat will automatically lock the buttons 10
seconds after the last adjustment.
