Setting The Current Operating Mode - Viessmann Vitocal 300 Operating Instructions For The System User

Setting the current operating mode

A setting change at this point only affects a change to the operating mode
until the next change-over initiated by the timer program.
Operating modes of heat pump/heating circuit:

temperature.
"Off" The heating circuit is switched off. The heat pump will only be
activated for heating DHW (if set) and to protect the system
against frost.
"Reduced" The heat pump/heating circuit will be regulated to the reduced
temperature.
"Fixed value Only for systems with a heating water buffer storage unit:
regulator" The storage unit will be heated independent of outside
temperature to the fixed value set by your specialist
