Line no. Operating line
2316 Temp differential max
2317 Temp differential nominal
PWM-Min Parameterized minimum speed of heating circuit or boiler pump
PWM-Max Parameterized maximum speed of heating circuit or boiler pump
Limitation of the boiler temperature increase in connection with a speed-controlled
pump (heating circuit or boiler pump) is only active in space heating mode. It is
deactivated as soon as there a request for DHW heating.
Prerequisite for limitation of the boiler’s temperature differential is a correctly working
sensor B7 and a parameterized upper limit for the permitted boiler temperature
differential: Temp differential max.
Line no. Operating line
2316 Temp differential max
The maximum boiler temperature differential in connection with a speed-controlled
heating circuit pump is maintained when the pump is controlled at the maximum
permissible speed.
The function can be deactivated by setting OSV (---).
Line no. Operating line
2317 Temp differential nominal
In connection with a speed-controlled heating circuit pump and pure Heating mode, the
nominal boiler temperature differential is maintained as long as the heating circuit pump
is not controlled at the maximum permissible speed.
