- 1 bit: This object is used to operate a switching actuating drive, e.g. a
thermoelectric positioner that is controlled by a switching/heating actuator.
- 1 byte This object is use to control an actuating drive with a continuous input value
(0%..100%), e.g. an electromotive actuating drive.

Status cooling
1 bit DPT 1.001
C, T
The room temperature controller sends an ON telegram via the "Cooling status" object as
soon as it is active in the cooling mode. If the controller is in the inactive zone between
heating and cooling or is in heating mode, the room temperature controller transmits an
OFF telegram on the "Cooling status" object.

Basic load
1 bit DPT 1.001
C, W, T, U
This object uses the value 1 to activate a parameterized base load, i.e. a minimum control
value greater than zero. The value 0 deactivates the base load. When the base load is
deactivated, the control value can be lowered all the way to zero if necessary when the
setpoint temperature is reach, despite the minimum value set in the parameter.
