Perform some quick tests:
Remove the Thermostat's batteries for one minute, then put them back in, checking their polarity: the display should flash.
If it doesn’t flash, try again with new batteries.
If it still doesn’t flash, please contact us.
If the display flashed in the last test, wait for the temperature readings to appear.
Now test the buttons (+) and (-): the Setpoint temperature should increase and decrease.
N.B. The buttons are not touch sensitive (you must hear a click).
If one of the buttons isn't working, or the Thermostat restarts and then the temperatures disappear as soon as you press the buttons, please contact us.
