Tab 26_ [Temperature control sequences - Main setpoint]
The main temperature setpoint are STH for heating and STC for cooling temperature control.
The active temperature setpoint (hereafter ATS) is then:
ATS=STH in heating
ATS=STC in cooling
Through parameters D02, D03, H12, H22, C12, they can be assigned to the specic sequence,
(see “6] Temperature control sequences”).
The main humidity setpoint are HUM for humidifying and DEH for dehumidifying control.
Main setpoint are accessible from the user interface in an shorten way, by pressing the DOWN key for 3 seconds.
Main setpoint are aected by economy mode and temperature compensation
6.4.1| Economy mode

By enabling the economy mode, the main temperature setpoint are changed by ES2 and ES3 quantity.
The Active Temperature Setpoint (ATS) becomes:
ATS=STH+ES2 in heating
ATS=STC+ES3 in cooling
