To prevent valves and drives becoming fixed place, “training period”

As soon switching action has been performed within seven days,
the switching output actuated for ten minutes 10:00 the fol-

- Comfort +21°C
- Lowering +18°C
- Cooling temperature +24°C
- Frost protection +10°C
A separate setpoint temperature can set which remains valid the
next programmed switching point, regardless the temperature levels.1 and 1. You can choose between the summertime regulation Central
Europe and Great Britain via parameter. 2370. The changeover between summer and winter time carried out
automatically. this way, the normal
time program can interrupted for four hours and you can
switch over the Comfort temperature.
