3iE Energy-Monitoring Thermostat

Quick Menu

How do I turn on my system?

To turn on your system once your thermostat has been installed, simply turn on the breaker. The thermostat screen will light up. After setting the basic parameters of the thermostat, select a steady temperature in manual mode for your first heating period to ensure the product heats up. Refer to the respective programming manuals.

If your screen is off and doesn’t light up, please verify that your thermostat faceplate is properly mounted against the base. There are two small screws at the bottom of the thermostat which you can loosen allowing you to remove the faceplate from the thermostat. Once you have taken off the face, press the reset button located on the back of the face and remount it to the back of the thermostat making sure the 8 gold pins tightly fit into their counterparts.  

It is also possible that the installer turned your thermostat off completely. This is done via the small ON/OFF button at the bottom of your 3iE thermostat. Refer to our post on the ON/OFF button to turn it back on.
