9.1 Solar function ON/OFF
(with FM 244 only)
The Solar function menu option is used to optimize the solar gain and minimize
the use of fossil fuel.
To achieve this, the controllers for the solar heating system and the conventional
heating boiler are combined in a single unit. The controls monitors the current
solar gain and the stored heat in the DHW tank, and reduces the setpoint
temperature in the standby part of the DHW tank to prevent it being reheated
unnecessarily.
