3 About the room thermostat
The room thermostat can be used to control Daikin systems. This
includes radiator heating and floor heating/cooling applications. The
room thermostat is typically connected to Daikin units. See the
"Application guidelines" chapter in the installer reference guide of
your unit for examples.
▪ In case of floor heating-only applications, the room thermostat can
be connected to the individual motorised valve of the floor heating
loop.
▪ If a floor heating-only application is used in combination with fan
coil units, each fan coil unit should have its dedicated fan coil
thermostat.
Optionally, the external temperature sensor EKRTETS can be
connected to the thermostat and used as:
▪ external ambient temperature sensor to control the room
temperature (instead of the internal temperature sensor of the
room thermostat). In this case, install the temperature sensor
where you want to control the ambient temperature.
▪ floor temperature sensor (only for floor heating/cooling
applications) to prevent dew on the floor in case of floor cooling. In
this case, install the temperature sensor in the floor. See
"6.3 To
install the external temperature sensor as floor temperature
sensor"
