Commissioning
Operation mode after reset
Options: - Heating
- Cooling
- Dependent on object "switchover heat / cool"
This parameter specifies the mode activated after resetting the temperature
sensor or after commissioning,
if heating/cooling switching is set to external.
Heating is preset, otherwise the operating mode can depend on the value
of the heating/cooling object. The device queries the value of the object over
the bus during initialisation.
Note:
The selection option "Dependent on object switchover heat / cool" is only
shown if the "switching between heating and cooling" is set to "Exterior".
Number of output channels
Options: - 1 channel (dual pipe system) for heat / cool
- 2 channels (four-pipe system) for heat / cool
If the "used control functions" parameter has been selected, it can be used
to specify whether a separate communication object or a common
communication object for heating or cooling is provided for the control value.
The setting "1 channel (dual pipe system) for heat / cool" is required for dual
pipe systems and the setting "2 channels (four-pipe system) for heat / cool"
is required for four-pipe systems.
