9. Temperature sensors used for regulation

9.1 Temperature sensors

Thermostat can measure temperature from two different sensors:
- Internal sensor: this sensor is embedded on thermostat.
- External sensor: This sensor is plugged at the back of thermostat. It can be used as
"ambient" temperature sensor or as floor temperature sensor depending of regulation
configuration.

9.2 Description of regulation configurations

Heating and cooling regulation can use two different temperature sensor. With respect
of external sensor connection, installer can choose a regulation type in parameter 20 in
installer menu (see paragraph 8 "Installer parameters").

Important points:
- to be able to select "Amb", "FLR" or "FLL" regulations in installer menu, external sensor
has to be connected to thermostat.
- If there is an error with external sensor and if installer/user goes to parameter menu
n°20, "AIR" regulation will be selected automatically and external sensor error could
be deleted if thermostat is turned off.

Description
Air regulation is done with internal
sensor.
Sensor measures temperature at the
thermostat position.
Ambient regulation is done with external
sensor.
Sensor measures at a different position
than thermostat position.
Floor regulation is done with external
sensor.
External sensor is connected to digital
thermostat and placed "in the floor".
Floor limit regulation with external sensor
and internal sensors.
External sensor is connected to digital
thermostat and placed "in the floor".
This measurement permits to check floor
temperature limits. Internal sensor is
used to do temperature regulation.
