8.2.2.7 Heating Circuit Switch-on Optimisation
Function: With this function the latest heating up time is calculated considering the outside and
room temperature (heat loss) to assure the desired room temperature at the set
occupancy start time.
The switch-on times saved in the switching time programs for the relevant heating
circuit do not refer any longer to the heating start time but to the occupancy start time
(i.e. the time when the desired room temperature is reached).
Calculation of the advanced switch-on time
= room setpoint at the start time (adjusted switch on time)
= max. optimization time (setting parameter)
= design outside temperature (climate zone)
= current optimization time
= outside temperature
This function can be complemented by an activation of the room influence if a room
device is connected (see description of room influence).
