Activation / Deactivation
The Backup heat.int. function is used for operating the electrothermal station for backup
heating with current from the mains. For this purpose, the power stages of the power unit and
the pump (R1) switch on. The switch-on and switch-off temperatures TOn and TOff are used as
reference parameters.
If the temperature falls below the adjusted threshold TOn, the power stages and the relay switch
on. They switch off if the temperature exceeds the threshold TOff.
S3 is used as the reference sensor (non-adjustable).
NOTE
For information on timer adjustment see page 14.

The Backup heat.ext. function is used for operating the electrothermal station for backup hea-
ting by means of an external heat source (e.g. heat pump, solid fuel boiler). The switch-on and
switch-off temperatures TOn and TOff are used as reference parameters.
If the temperature falls below the adjusted threshold TOn, R2 is energised at 100 %. It switches off
if the temperature exceeds the threshold TOff.
S3 is used as the reference sensor (non-adjustable).
