Saving energy without sacrificing comfort
• During the day, do not allow the room temperature to
exceed 21 °C. Each additional degree increases heating
costs by 6 to 7 %
• Guide values for room temperatures in living and
working spaces:
− During the day: Precomfort = 19 °C, Comfort =
20…22 °C
− During the night: Economy = 14…18 °C
− Longer nonoccupancy times, such as holiday peri-
ods: Protection = 10 °C.
Protect objects sensitive to low temperatures, such
as plants!
• Air spaces for only short periods of time, with the
windows fully open
• Set thermostatic radiator valves in unoccupied rooms
to their frost protection position
• Closed shutters and blinds reduce heat losses
• Ensure that there are no curtains, furniture or other
objects in front of the radiators. They reduce the emis-
sion of heat
• Check heat energy consumption at regular intervals
If your plant uses a room temperature sensor (or room
unit), it should not be exposed to thermal disturbances
since these have an impact on the control function. For
this reason, following applies to the reference room
where the sensor is located:
• Avoid drafts through open doors
• Avoid heat gains caused by people, machines, light-
ing, etc., near the sensor
• Ensure that air circulation near the sensor is not ob-
structed by curtains, furniture or other objects
• Set thermostatic radiator valves, if present, to their
fully open position
Energy savings do not only conserve our natural resources, they also ensure active environmental protection!
