CAUTION! When the household thermostat input works in the mode of adaptation,
any attempts to change the boiler programmed temperature may end with failure, i.e.
when the new value is confirmed, the change in the boiler programmed temperature
to the value resulting from the algorithm of adaptation is automatic.
CAUTION! If the heating system is fitted with the domestic water tank, boiler water
temperature controlled and maintained by the controller during tank preheating may
be higher than desired temperature setting programmed with thermostat knob.
