Wireless Gas Boiler Thermostat For Electric Radiator
ST2401RF is the version of our RF pair built for electric radiators, where the switched load is much higher than a boiler relay. The receiver is offered at 6A or 16A on 230V AC, so a direct electric heater can be switched without an external contactor. The room unit runs from 2 x AAA 1.5V lithium batteries, carries a Heat / Off / Cool switch, a low battery indicator and a Fahrenheit or Celsius display option.
Key Benefits
- 16A receiver option switches electric radiators directly, with no contactor to house
- Battery powered room unit can be sited anywhere without a supply
- Low battery indicator warns before the room loses control
- F or C display makes the same product suitable for several export markets
- Room temperature calibration corrects a warm or draughty mounting position
Problems It Solves
- Thermostat contacts too small for direct electric heater loads
- Extra contactor enclosures adding cost and wall space
- Batteries dying without warning and leaving a room uncontrolled
