Underoor heating
Why control the oor heating?
To maintain the required oor temperature and room temperature.
How is oor heating used?
WISE IRT is used to measure the surface temperature of the oor
and the room temperature. An actuator for the oor heating
circuit is controlled via a WISE IORE. The oor heating limits so
that the oor does not exceed a set temperature. A value for the
oor temperature between 15–30°C with an oset for switching
on and o can be set. It is possible to hold a higher temperature
on the oor compared with the room temperature.
There is a separate output signal to control the oor heating,
adjustable as for radiators and comfort modules with a heating
coil, 24 V NO/NC On/O or PWM and 0-10 V Analogue.
Floor heating control is divided into dierent types. Either only
the oor’s surface temperature is regulated or the temperature
of the whole room is regulated. It can also regulate the temper-
ature as a separate zone in the room. In this instance the zone
temperature is measured with a separate temperature sensor,
see the table below.
When the room goes from no occupancy mode, it is possible to
set so that the oor heating remains on as if the room was in
occupancy mode for an adjustable number of minutes.
Flooding alarm
There is support to connect a sensor for water leakage, which
can be used to detect water leakage in the oor heating instal-
lation. An alarm is generated when the sensor detects water
leakage. This sensor can be connected to the same WISE IORE
that is used to control the oor heating.
Operating case
If the temperature sensor for the zone temperature fails, the
system switches to surface heating aer an alarm has been
tripped. If the surface temperature sensor fails the oor heating
switches to the set xed output, even then an alarm is tripped
to inform the user.

Underoor heating Fixed output 30 0 100 % Installation/Installation
Fixed output, for output regulation of oor heating
or for the loss of temperature sensors.
Underoor heating Post-running time comfort 0 0 1200 Minutes Installation/Installation
Can be used so that the oor heating remains
on as if the room was unoccupancy mode for an
adjustable number of minutes.
