Heating control unit
Use a heating control unit with room temperature influence or an outdoor reset
control unit and thermostatic valves.
For further information, see the operating instructions for the heating control unit
included in the scope of delivery.
Thermostatic valves
Fully open the thermostatic valves to ensure that the desired room temperature is
reached in all cases. Allow several days for the system to stabilize after every
adjustment and only change the setting for the heating curve or the room
temperature on the control unit after the system had stabilized on the previous
settings.
Radiant floor heating
Do not set the supply temperature higher than the maximum level recommended by
the manufacturer.
Room venting
Do not keep windows cracked for ventilation purposes as it continuously cools down
the room without significantly improving the air quality in the room. It is better to vent
fully for a short time (with completely open windows).
Turn off the thermostats (if installed) in the room when venting.
Domestic hot water (DHW)
Always set the DHW temperature as low as possible.
A lower setting on the thermostat means a higher rate of energy savings.
Furthermore, higher DHW temperatures result in increased limescale deposits and
thereby may impair the function of the appliance (e.g. longer heating-up times or
lower output).
Recirculation pump
If there is a DHW recirculation pump installed, use a timer program to control its
operation according to the specific requirements (e.g. morning, afternoon,
evening).
