11.3.66
Combined heating and cooling modes - Additional heating/cooling stage control value output
Options:
Via 1 object
Via 2 objects
This parameter is used to define whether the control value is transmitted to the climate control
actuator using one or two objects. If the climate control actuator has separate control value
inputs for heating and cooling, or if separate actuators are used, then the option "Via 2 objects"
must be selected. Select the option "Via 1 object" if a single actuator only has one object that
receives both the heating and the cooling control values.
Note
This parameter is only available when the "Control function" parameter is set on
"Heating and cooling with additional stages".

Setpoint settings
Note
This parameter is only available if the "Device function" parameter is set on either
"Single device" or "Master device".

11.3.68
Setpoint settings - Setpoint for heating comfort = setpoint for cooling comfort
Options:
No
Yes
This parameter is used to configure the manner in which the setpoint adjustment functions.
–
Yes
: The device has the same setpoint for heating and cooling in the comfort mode. The
system switches to heating when the temperature drops below the setpoint minus
hysteresis. It switches to cooling when the temperature exceeds the setpoint plus
hysteresis. The hysteresis is parameterizable.
–
No
: The function has two separate setpoints for heating and cooling in the comfort mode.
The device will display the currently active setpoint value. Switching between heating and
cooling occurs via the "Switchover heating/cooling" parameter setting.
Note
This parameter is only available when the "Control function" parameter is set on
"Heating and cooling" or "heating and cooling with additional stages".
