Select base setpoint
Options:
- Dependent setpoints
- Individual setpoints
The "Select base setpoint" option defines whether the room thermostat refers to "Dependent setpoints" or to "Single
setpoints".
Dependent setpoints mean that a comfort temperature (base setpoint) is defined and other setpoints such as
temperature at standby or automatic night setback refer to this temperature.
The standby temperature 2 K is set lower than the comfort temperature (base setpoint). At a comfort temperature of
21 °C this means a standby temperature of 19 °C. If you raise the comfort temperature to 22 °C by manually moving
the setpoint, the standby temperature is automatically changed to 20 °C.
The setting "Single setpoints" allows you to choose a separate temperature on the room thermostat for each setpoint;
the room thermostat always refers to this setting in the respective operating mode.
Example: the standby temperature is set permanently at 19 °C. If you raise the comfort temperature from 21 °C to
22 °C by manually moving the setpoint, the standby temperature does not change.
Reference base setpoint
Options:
- Setpoint heating
- Setpoint cooling
- Mid zone of the dead zone
If "Dependent setpoints" were selected with "Heat and cool" controller function and selection of base setpoint, this
parameter can be used to define whether the base setpoint refers to comfort temperature for heating, cooling or the
average temperature between "Heat and cool" (see also page 71, Section 7.4.3 Minimum interval).
"Setpoint heating" is the default setting. In regions where the cooling function is more important, it is recommended
that you change this parameter to "Setpoint cooling". This makes it easier to set the room thermostat and raise the
cooling setpoint (standby temperature cooling and automatic night setback).
This parameter is only available if the "Heat and cool" control functions are set.
Manual setpoint adjustment at reset of change from night / to night
Options:
- Yes
- No
If this parameter is set to "Yes", the setpoint offset is automatically reset when switching operating modes from night
and to night.
If a setpoint is adjusted manually, the increase or reduction of the setpoint can be cancelled if the operating mode
is changed, e.g. on receipt of a telegram from a timer. This means that if the parameter is set to "Yes", the manually
adjusted setpoint will be rejected if the operating mode changes and it will be reset to the setpoint preset in the
parameter.
