Room temperature controller | Operating mode and setpoints
10.3.1 Operating mode and setpoint parameters
Overwrite setpoints in device during ETS
programming operation
The setpoint temperatures programmed in the room temperature controller by the
ETS during commissioning can be changed via communication objects. This para-
meter can be used to define whether the setpoints present in the device, which may
have been changed subsequently, are overwritten during an ETS programming op-
eration and thus replaced again by the values parameterised in the ETS. If this para-
meter is "Yes", then the setpoint temperatures are deleted in the device during a pro-
gramming operation and replaced by the values of the ETS. If this parameter is con-
figured to "No", then setpoints present in the device remain unchanged. The setpoint
temperatures entered in the ETS then have no significance.
Setpoint presetting
It is possible to configure the setpoints for the "Comfort", "Standby" and "Night"
modes directly (absolute setpoint presetting) or relatively (derivation from basic set-
point). This parameter defines the way the setpoint temperature is preset.
With "Relative": All temperature setpoints are derived from the basic temperature
(basic setpoint).
With "Absolute": The setpoint temperatures are independent of each other. Different
temperature values can be specified for each operating mode and heating/cooling
mode.

Heating
Comfort
With absolute setpoint presetting the setpoint temperatures for Comfort, Standby
and Night mode are independent of each other. Depending on the operating mode
and heating/cooling mode, various temperature values can be specified in the ETS
within the range +7.0 °C to +40.0 °C. The ETS does not validate the temperature
values. It is thus possible, for example, to select smaller setpoint temperatures for
cooling mode than for heating mode, or to specify lower temperatures for Comfort
mode than for Standby mode. After commissioning using the ETS the setpoint tem-
peratures can be changed via the bus by means of temperature telegrams. This can
be done using the communication object "Setpoint temperature - Active operating
mode".
