The time programmes are only effective in the Automatic
mode (→ Page 21). The desired temperature that you set
in the Desired temperatures function applies in each set
time period. Within the time period, the controller switches
to Comfort mode and the heating circuit heats the con-
nected rooms up to the desired day temperature. Out-
side this time period, the controller switches to the set-
back mode and the heating circuit heats the connected
rooms to the desired set-back temperature.
Set the time period for the heating circuit so that each time
period:
–
starts approx. 30 minutes before the time at which the
rooms should reach the desired day temperature.
–
ends approx. 30 minutes before the time at which the
rooms should reach the desired set-back temperature.
