Introduction - Daikin EKRTR Installation Manual

1. Introduction

The room thermostat EKRTR can be used to control the Daikin
system (radiator heating and floor heating/cooling applications).
It is typically connected to the Daikin unit. Refer to the "Typical
application examples" in the Installation manual of the Daikin
unit.
In case of floor heating-only applications the room
thermostat can also be connected to the individual motorized
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, an 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 temperature sensor inside the
thermostat). In that case, install the temperature sensor
where you want to control the ambient temperature.
floor temperature sensor (only for floor heating/cooling
applications) to protect the floor temperature or to prevent
dew on the floor (in case of floor cooling). In that case, install
the temperature sensor in the floor (refer to
EKRTETS as floor temperature sensor (only for floor
heating/cooling applications)" on page
In case of extreme or sudden changes in weather
conditions, despite the dew prevention function,
condensation on the floor could occur.
To avoid reoccurrence, we suggest changing the
field settings (refer to
protection and dew prevention function (only for
floor heating/cooling applications)" on page
In case the conditions are so extreme that this
countermeasure is not adequate, we suggest not
to use floor cooling.
