The ESRTERFW is a battery-powered Electronic Room Thermostat that is economical and simple to use.


Simply turn the control dial to the desired temperature to control the room temperature. The ESRTERFW includes an LCD display which displays the current room temperature. When the temperature is adjusted, the LCD display will briefly display the revised temperature before returning to the current room temperature. A small flame symbol will appear on the LCD display when the system is being turned ON. When the system is being turned OFF, the flame symbol will no longer show on the LCD display.


The modern and stylish range of Electronic Room Thermostats from ESi Controls are designed to outperform many older thermostats and should be able to produce savings in the order of 10% over and above those achieved by traditional units using an older technology. The temperature control accuracy of +/- 0.6°C will reduce the temperature swing that normally occurs with older style thermostats.


The ESRTERFW is a two-wire installation with Volt Free contacts and a wireless thermostat (transmitter) with an easy fit backplate for quick and easy installation. A simple to use, a modern replacement for traditional room thermostats with real energy savings.
