  • Thermostatically controlled valve
  • Zone control for a manifold (per floor)

This kit for 1-zone control allows you to control the manifold as one zone by means of a 1 zone controller and thermostat (this is particularly suitable for floor heating systems that heat one room).

A digital clock thermostat is part of the kit, but you are also able to replaced for an ON/OFF thermostat. You can do this by changing the content of the kit by selecting “options”.


The thermostatic valve is placed in the supply pipe to the manifold and the actuator is placed on the valve.
The actuator is connected to the receiver, which is wirelessly operated by the thermostat.

Please Note

You cannot use this kit when you make use of one manifold and you want to be able to set individual room or zone temperatures.

If you want the thermostat to be able to wirelessly operate the 1 zone receiver and your boiler. You require a second receiver in order to do so.
