Grand Meyer® HW500 / HW800


Programmable thermostat with a modernized design for underfloor heating control. Can be used in manual or automatic mode. Possibility to set a weekly program in 5+2, 6+1 or 7-day modes. Settings are saved in case of power failure. Built-in temperature sensor and 3 m long external NTC sensor are included. Maximum load up to 16 A. HW500 is white, HW800 is black. The thermostat controls underfloor heating according to the readings of the external sensor, internal room sensor, or a combination of both. Designed for flush wall mounting.

Simplicity and convenience:

The thermostat offers manual and programmable control according to needs.


Temperature sensors:

The thermostat maintains temperature according to the readings of the floor, room, or both sensors.


External sensor installation:

If using the internal or both sensors, the thermostat must be installed on a wall in a place with good air circulation. The external sensor must not be placed near heat sources (sunlight, radiators), doors or windows, or in direct thermal radiation.
