Operating Mode And Setpoints - Gira KNX 2139 00 Product Documentation

Room temperature controller | Operating mode and setpoints
Heating/cooling switchover
In a configured mixed mode it is possible to switch over between heating and cool-
ing.
With "automatic via RTC": Depending on the operating mode and the room temper-
ature, the switchover takes place automatically.
With "via object": The switchover takes place only via the object "Operating mode".
Additional stage inhibit object
The additional stages can be separately disabled via the bus. The parameter en-
ables the disable object as necessary.
This parameter is only visible in two-level heating and cooling operation.
Controller output disabling object
This parameter enables the "Disable command value outputs" object. If the controller
is disabled, there is no feedback control until enabled (command values = 0).
Operation mode after reset
This parameter specifies which operating mode is set immediately after a device re-
set.
With "Restore operation mode before reset": The mode set before a reset according
to the operating mode object will be restored after the initializing phase of the device.
Operating modes set by a function with a higher priority before the reset (Forced,
Window status, Presence status) are not effected.

Operating mode and setpoints

Introduction - Operating modes
The room temperature controller has various operating modes. The selection of
these modes will, for example, facilitate the activation of different temperature set-
points, depending on the presence of a person, on the state of the heating or cooling
system, on the time of the day, or on the day of the week. The following operating
modes can be distinguished:
– Comfort
Comfort mode is usually activated if persons are in a room, and the room tem-
perature should, for this reason, be adjusted to an adequately convenient
value. The switchover to this operating mode can take place either by specify-
ing an operating mode via the operating mode switchover or with presence
control, for example, using a PIR presence detector on the wall or a ceiling
mounted presence detector.
– Standby
