If enabled in the ETS, 6 temperature setpoints can be varied in "heating and cooling" control option. Depending on
the temperature decrease, increase or dead zone parameterized in the ETS, all temperature setpoints are derived
from the basic setpoint temperature.
It must be pointed out that changing the setpoint temperature for heating in the comfort mode will also change all
other setpoint temperature values!
The dead zone (temperature zone for which there is neither heating nor cooling) is the difference between the
setpoint temperatures for "heating" and "cooling" in the comfort mode. The following applies:
T
comfort setpoint cooling
Important notes:
- If the dead zone is symmetrical, the basic setpoint is indirectly set via the comfort temperature for heating.
- Changing the comfort setpoint temperature for cooling allows the adjustment of the dead zone. An
adjustment of the dead zone with a symmetrical dead zone position will result in a shift of the comfort
setpoint temperature for heating and thus of all other temperature setpoints. With an asymmetrical dead zone
position, an adjustment of the comfort setpoint temperature for cooling will only shift the temperature
setpoints for cooling. It is possible to shift the dead zone to 0 °C via local control (T
). In this case there is neither heating nor cooling, if the determined room temperature equals the
setpoint heating
comfort setpoint temperatures.
The setpoint temperatures for "Standby" and "Night" are derived from the comfort setpoint temperatures for
heating or cooling. The temperature increase (for cooling) and the temperature decrease (for heating) of both
operating modes can be preset in the ETS.
