Grand Meyer® HW800

Programmable temperature controller with an updated design for underfloor heating control. Possibility of programmable and manual control. Possibility to set a weekly period of 5+2/6+1/7 days. Memory settings when power off. Built-in temperature sensor and external NTC sensor 3 m long. Maximum load up to 16A. HW800 has black body color. The temperature controller controls the operation of the underfloor heating according to the readings of the floor temperature sensor (included in the delivery set) or according to the readings of the ambient air temperature build-in sensor, or a combination of both sensors. The temperature controller HW-800 is designed for hidden (recessed) mounting in the socket of the mounting box.

Simplicity and comfort

The temperature controller has programmable and manual control functions.

Button control

Датчики температуры​

Терморегулятор автоматически поддерживает заданную температуру обогреваемой поверхности по показаниям датчика температуры пола (входит в комплект поставки) или по показаниям датчика температуры окружающего воздуха (встроен в регулятор), или в комбинации обоих датчиков.

Temperature sensors

The temperature controller automatically maintains the set temperature of the heated surface according to the readings of the floor temperature sensor (included in the delivery set) or according to the readings of the ambient air build-in temperature sensor, or a combination of both sensors.

Location of the external temperature sensor

When using a built-in sensor or a combination of both sensors, the temperature controller must be installed on a wall with free air circulation around it. In addition, it should be placed where there is no exposure to another heat source (sun, radiators, etc.), from doors or windows, or exposure to ambient temperature.
