Condensate water alarm
Number
29
This 1-bit communication object is used to place the controller in the condensation alarm mode.
This causes the current setpoint value to be set to the heat protection setpoint value in order to
keep the structure from being damaged by an overflowing condensation container.
Note
Item 1:
This protective mechanism is only active in the cooling mode. It remains in place
until it is cancelled by the value (0). When an alarm is active, manual operation of
the controller is blocked. This information is indicated by a corresponding icon on
the device.

Outside temperature for summer compensation
Number
30
In order to save energy, and to ensure that the temperature difference occurring during entry
and exit of a climate-controlled building stays within comfortable limits, the reduction of room
temperature by cooling devices should be limited as a function of the outside temperature
(summer compensation). This, for example, prevents the air-conditioning system from further
reducing the room temperature to 24°C with an outside temperature of 35°C.
This function can only be used with an outside temperature sensor. This 2-byte communication
object must then be used to provide the controller with the current outside temperature.

operation of the controller is blocked. This information is indicated by a
corresponding icon on the device.
When the master/slave mode is active, the condensate water alarm
(master/slave) objects must be connected to the alarm transmitter.
