Operating the BC10 basic controller
Explanation
No supply to heating system (only DHW heating
operation).
The temperature set on the BC10 acts as a high limit.
With a AM10 or RC10 control, the water temperature
will be at a equal or lesser value. With a On/Off
thermostat the water temperature will always be the
set temperature. Supply temperature never rises
above the set temperature.
The temperature high limit setting defaults to the
maximum boiler water temperature of 180 °F (82 °C).
