Electric Thermostats

RET MD



- Intelligent heating control for increased fuel economy
- Micro-processor accuracy
- Setting dial with LCD temperature display
- Wallplate contruction for ease of installation


RET-MD thermostat combines the ease of use benefits of a setting dial together with the accuracy and advanced features, including LCD display, that are only available from micro-processor based controllers. The LCD display, that normally shows actual room temperature, changes momentarily to show set temperature whenever the setting dial is moved. Styled upon the RET room thermostat, the RET-MD can be set up by the installer to provide either traditional on/off control or more sophisticated chrono-proportional control for increased comfort and economy.

The RET-MD is an intelligent room thermostat that incorporates an energy saving delay start feature, which delays the start-up of the heating dependent upon how close to set-point the room temperature is at the time the central heating time switch is scheduled to turn on the heating system. Under most load conditions, this feature reduces the number of hours per day that the system runs, without creating any discomfort. This feature can, if necessary, be cancelled if the user wishes to override the delay period.

The RET MD is ideal for use with combination boilers and can be installed without the need for complicated wiring or commissioning.
