Description of room unit settings
2015-09-16
The programmed heating curve is based on a room setpoint of 20°C. If the room
setpoint is adjusted, the heating curve automatically adapts to the new value.
The summer / winter changeover temperature is the criterion for automatic summer
/ winter changeover of the heating plant.
It offers the following benefits:
·
Fully automatic operation throughout the year
·
The heating will not be switched on when the outside temperature drops for
short periods of time
·
Additional savings function
By changing the setting, the respective periods of time will be shortened or
extended. The change will only affect the heating circuit.
Increase: Winter operation will start
earlier
Summer operation will start
later
.
Decrease: Winter operation will start
later
Summer operation will start
earlier
To determine changeover, the setting of the summer / winter changeover
temperature
( ± a fixed switching differential) is compared with the attenuated outside
temperature.
