Basic set-up
The controller can control the DHW temperature with either
one or two tank temperature sensor(s). The controller will
automatically register the number of sensors.
1 Cut-out temperature difference - (lower sensor)*
Circuit Setting range Factory setting
I 1 ... 99 K 15 K
Set the difference between the desired charging temperature and
cut-out temperature (charging stop) .
Set the difference.
Example:
Desired charging temperature (section 3): 60 °C
Cut-out difference:
15 K
Calculated cut-out temperature (60-15) = 45 °C
2 Cut-in temperature difference - (upper sensor)*
Circuit Setting range Factory setting
I 1 ... 99 K 20 K
Set the difference between the desired charging temperature and
cut-in temperature (charging start).
Set the difference.
Example:
Desired charging temperature (section 3): 60 °C
Cut-in difference:
20 K
Calculated cut-in temperature (60-20) = 40 °C
* In case of two sensors.
