GRAND MEYER HW500 16A 230V PROGRAMMABLE THERMOSTAT

Programmable thermostat with a modernized design for controlling underfloor heating. Allows for both programmable and manual control. Option to set a weekly schedule in 5+2, 6+1, or 7-day modes. Settings are retained in the event of a power outage. Built-in temperature sensor and external NTC sensor with a 3-meter cable. Maximum load up to 16 A. The HW500 is available in white. The controller regulates the operation of the floor heating based on readings from the floor temperature sensor (included), the built-in room temperature sensor, or a combination of both sensors. Designed for flush mounting in a wall-mounted junction box.
