Watts MILUX RF Wireless Transmitter Only

The Watts MILUX RF Wireless Transmitter Only 433MHz is a programmable room thermostat, that transmits a wireless radio frequency (RF) signal to control a connected heating or cooling receiver unit.

Key Features and Function

Function: It is designed to measure the room temperature and allow a user to set a desired heating schedule and temperature. It then wirelessly transmits commands (like "turn heating on" or "turn heating off") to a separate receiver unit (which is wired to the boiler or underfloor heating manifold).

Programmability: Like other MILUX thermostats, it features a digital display and controls for weekly programming, allowing for different temperature settings (Comfort, Reduced, Anti-freeze) at different times of the day and week, thus helping to manage energy usage.

Power Source: The transmitter unit is battery-powered, allowing it to be placed freely on a wall in the living space without needing a wired connection to the heating system.

It is essential to note that as a "Transmitter Only" unit, it requires a compatible Watts 433MHz receiver (not included) to actually switch the heating system on or off.
