If a 0 telegram is received, the controller switches to OFF mode and regulates the
temperature to the setpoint value for frost/heat protection. When the controller is switch
on again, the remaining operating mode objects are required in order determining the
new operating mode.
12.35.5 General – Additional functions/objects – Fault actual temperature - Object
no
Object name
Fault actual temperature
Fault actual temperature –
(master)
Fault actual temperature –
(slave)
Item 2: This object must be connected to the "Fault, actual temperature (slave)" object in
order to indicate the error mode.
Item 3: This object must be connected to the "Fault, actual temperature (slave)" object in
order to indicate the error mode.
If one of the parameterized input temperatures is unavailable to the controller for a period
longer than the monitoring time, the controller enters the error mode. The error mode is
sent to the bus as the value 1.
12.35.6 General – Additional functions/objects – Window contact - Object no
Object name
Window contact
Item 2: If the master/slave mode is active, the "Window contact (master/slave)" object of
the master and the slave must be connected to the group address of the transmitter.
The object uses the value 1 to signal an open window to the controller. If no other object
with a higher priority is present, then the "Window contact" message causes the controller
to be set to the setpoint value for frost/heat protection. In addition to manual setpoint
adjustment and the adjustment of the basic setpoint value, the setpoint temperature of
the controller can also be defined by objects "Superimposed operating mode",
"Condensate water alarm", "Dew alarm", "Window contact", "Control On/Off", "Presence
detector" and "Operating mode (listed in decreasing order of priority).
