The room thermostat EKRTWA 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.

The EKRTWA thermostat is wall-mounted, with supplied screws
and plugs. Refer to figure 1.
Cabling towards the Daikin system (field supply) should be
foreseen in advance taking the suggestions for an ideal
