RET MD

Electronic Intelligent Room Thermostat

User & Installation Guide

- Turn setting dial to required temperature which is displayed momentarily on the LCD display. The LCD reverts to

displaying actual room temperature within a few seconds.

- If Time Control is activated the green LED is lit.

- If the red LED is lit constantly, the heating is switched on.

- If the red LED is flashing, the Delay Start function is in operation.

- If the Save button is pressed while the heating is on, the Delay Start function will start. This can save energy by

switching the heating off once the room is up to temperature for the duration of the delay period (refer to Delay Chart

overleaf). Pressing the Save button a second time will return the thermostat to normal operation and the heating will

start.

- If the green LED is on, but the red LED is off, the room temperature has been reached and the thermostat is satis-

fied. If more heat is required turn the setting dial to increase the set temperature.
