Wall-mounted heating controller W80001

remotewirelessfor underfloor heating

Product overview
MAGNUM Remote Zone Control (MAGNUM W) is a modular system for zoned underfloor heating control. The system comprises wall/room thermostats, a central receiver/controller mounted by the manifold and electrothermal actuators on manifold valves. Thermostats transmit temperature demand to the receiver, which drives actuators to open or close zones. Zones can be controlled individually from the thermostat or remotely via tablet/smartphone app.

MAGNUM W‑Controller
The MAGNUM W – Controller (MW‑C) is a receiver designed to manage "normally closed" actuators in water‑based underfloor heating installations. Each MW‑C handles up to 8 zones and can be expanded in series to cover larger installations.

MAGNUM W‑Thermostat
The MAGNUM W – Clock Thermostat (MW‑T) delivers accurate room temperature control with programmable schedules. The wireless thermostat communicates with the MW‑C receiver and sends setpoint changes and demand signals to open/close actuators as required.

MAGNUM W – Actuators
MAGNUM W electrothermal actuators (MW‑A) mount directly on manifold valves to automatically control water flow. When a zone requires heat, the thermostat signals the MW‑C, which energises the actuator to open the valve; the actuator closes the valve once the set temperature is reached.
