1. Introduction

 

The room thermostat EKRTW can be used to control floor
heating-only applications and floor heating/cooling applications.

It is typically connected to the indoor unit. Refer to the "Typical
application examples" in the Installation manual of the indoor
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.
