Raychem NRG-DM Thermostat

 

Raychem NRG Thermostat.

The Raychem NRG Thermostat is a digital timer thermostat for floor sensing or/and room sensing applications. Including min. and max. floor temperature limitation function.

The timer function is programmable for each day of the week in 30 minute blocks. Alternatively there are 2 selectable pre-programmes.

Raychem NRG Thermostat has an intelligent adaptive function. This calculates when the heating is to be switched on to make sure that the comfort temperature is reached when required.
