Mains operated electronic room thermostat

Mains powered electronic unit, with load compensation for new and replacement installations. Temperature setting range 5-30 °C. This is part of a range of purpose designed room thermostats, offering the latest energy saving control technology combined with established Secure design and manufacturing expertise. This makes them suitable for use in most types of heating systems that respond to a 230V mains electrical On/Off signal. They are also perfect partners for use with our range of programmers and zone valves. Designed to look good, these thermostats will outperform many older styles of thermostat and can often produce savings in the order of 10% over and above those achieved by traditional units using older technology. Temperature control accuracy of +/- 0.5°C and different settings (for gas, oil and electric systems) will reduce the temperature swing that normally occurs with older style thermostats
