Room temperature controller | Floor temperature monitoring
Maximum permissible floor temperature
The maximum limit temperature which the floor may reach in heating mode is spe-
cified here. If this temperature is exceeded, the controller switches the underfloor
heating system off using the command value. As soon as the floor temperature has
fallen 1 K under the limit temperature, the controller switches the command value on
again, assuming that this is provided for in the control algorithm.
Cooling
Minimum permissible floor temperature
The minimum limit temperature which the floor may reach in cooling mode is spe-
cified here. If the temperature falls below this value, the controller switches the un-
derfloor cooling system off using the command value. As soon as the floor temperat-
ure has risen 1 K above the limit temperature, the controller switches the command
value on again, assuming that this is provided for in the control algorithm.

1-bit object for the status output of the monitoring of the configured limiting values of
the floor temperature. If the monitoring is enabled in the ETS, the controller continu-
ously monitors the floor temperature. If the floor temperature exceeds a specified
limiting value during heating or falls below a specified limiting value during cooling,
the controller switches off the corresponding command value for heating or cooling.
This switches off the heating or cooling. The controller will only set the most recently
calculated command value again when the temperature exceeds / falls below the
limiting value minus a hysteresis of 1 K again.

2-byte object for coupling an external temperature sensor for floor temperature mon-
itoring.
The temperature value must always be specified in the format "°C".
