There are a bank of 4 DIP switches available by accessing the user interface board (usually set to OFF position). These can be of use when complaints of temperature related problems.
DIP switch 1 and 2 are Pump Settings.
Both OFF = Pump runs with Demand
Both ON = Pump runs constantly
DIP switch 3 and 4 are Boiler Temperature Settings
On earlier interface models
3 ON = Reduces boiler CH temperature to 73°C
Later interface models (with COM1 and COM2 potentiometers)
3 OFF = Reduces boiler CH temperature to 73°C
3 ON = Increases boiler CH temperature to 87°C
3 and 4 ON = Reduces boiler temperature to 53°C
(This is usually for under floor heating)
