Troubleshooting
If your Cielo Smart Thermostat doesn’t turn on, please try these steps:
1. Close your HVAC panel properly, as some systems may not work if the panel isn’t fully
closed.
2. Check the backplate wire connections and ensure they are inserted properly into the
terminals.
3. In the case of one R-Wire, make sure it is inserted into the RC terminal.

In case of more than one R-Wire, make sure RH is inserted into the RH terminal and RC or
R is inserted into the RC terminal.
4. If you installed the C-Wire Adapter, ensure all wires are connected to the correct terminals
on your thermostat.
