Switching the comfort function ON and OFF

Only for Vitodens 300 with integral instantaneous water heater.
The instantaneous water heater is held at temperature (standby), as long as the
comfort function is switched ON. Hot water will then be available instantly.
The comfort function can be switched
OFF with /, to prevent the boiler
starting up, thereby saving the energy
required to maintain standby mode
when no hot water is drawn, e.g. at
night.
