– Cooling: For operating a cooling-based automatic single-room control. The temperature
is regulated to the setpoint value defined in the parameter. The "Controller type" and
"Cooling type" can be program for optimal control.
– Cooling with additional stage: In addition to the control function described under cooling,
the additional stage enables the activation of an additional cooling device. This type of
additional stage is use, for example, to cool a room quickly via an added cooling device.
– Heating and cooling: For operating a two-wire or four-wire system used to heat or cool
a room. Switching between heating and cooling takes place using a central switch (two-
wire system) or is carry out manually and / or automatically via the single room
temperature controller (four-wire system).
– Heating and cooling with an additional stage: In addition to the heating and cooling
functions, one additional stage each with an autonomous controller type can be program.
12.34.6 General – Operating mode after reset
Options
Note: This parameter is only available if the "Device function" parameter is set
on "Single device" or "Master device".
After a reset the device will run in the operating mode after a restart until a new operating
mode is set as the result of device operation or by communication objects, as the case
may be. This operating mode should be defined during the planning phase. An improperly
defined operating mode can result in a loss of comfort or increased energy consumption.
– Comfort: If the room temperature is not automatically lower and the room is therefore
controlled independent of its use.
– Standby: If the room is controlled automatically, e.g. by a presence detector, as a
function of its use.
– Eco mode: If the room is controlled automatically or manually as a function of it use.
– Frost/heat protection: If only the building protection function is necessary in the room
after a reset.
12.34.7 General – Send cyclic "In operation" (min)
Options
– The "In operation" communication object serves to inform that the controller still
operates. Value "1" is sent cyclic. This parameter is use to set the cycle for sending. If the
cyclic telegram fails, the function of the device is faulty and the air-conditioning of the
