You must provide external power to your thermostat in order for it to function properly. This power can come from the HVAC unit in your home, or from an external
transformer. If your Thermostat is properly setup to control your HVAC system, but you cannot access it from the website, it likely that the thermostat is not powered properly.
To verify the thermostat has power, please remove the batteries while your thermostat is still connected. If the screen on your thermostat is blank when you remove the batteries, then you don't have power to the thermostat.
This page will give you a number of examples on how you can power your thermostat.
Method 1: Connect your "C" Wire
with Existing Cabling
Often times there are extra wires in the wall, and you can use one of those wires to power your Thermostat. Follow the directions below:
Turn off power to your HVAC
Find your thermostat terminal block inside of your HVAC unit (you most likely have to remove a protective panel)
Connect one of the extra wires to the "C" terminal on your HVAC unit (this likely has a "C" label, and possibly has another wire connected to it)
Connect the other end of the same wire to the "C" terminal on the thermostat
Replace protective panels on the thermostat and power back on your HVAC
Test that the thermostat has power by removing the batteries. If the screen stays on when the batteries have been removed, then you have successfully applied power to the thermostat.
Method 2: Power your thermostat with an External Transformer
If you don't have an extra wire in the wall, you can power your thermostat with an external transformer. If you don't already have one, you can purchase one from our online store at
http://store.radiothermsotat.com. Once you have a 24VAC transformer, follow the steps below to apply power to your thermostat:
Connect one wires from the external transformer to the "C" terminal on the thermostat.
Connect the other wire to the "Rh" terminal
Plug in your external transformer
