Common Problems

Blank Thermostat

If you notice your thermostat screen is blank or unresponsive, please first check to see if it has replaceable batteries. Older thermostats require infrequent battery replacement and the solution might be simple. If you have a smart thermostat like the Nest or Ecobee, this could mean it was installed incorrectly, it could indicate the HVAC system has lost power or tripped a breaker. Call Paragon right away if you encounter a blank thermostat and the batteries have been replaced.

Power Cycling

With smart thermostats like the Nest Learning Thermostat and Ecobee becoming more prevalent in homes throughout the Chicagoland area, so have problems associated with their unique wiring needs. If you notice your HVAC system frequently turning on and off, call Paragon immediately as your thermostat may be wired incorrectly or your HVAC system might be failing.

Error Codes

If your thermostat is displaying an error code/message of any kind, it usually indicates there is a problem with the system it is controlling. While some problems can easily be resolved with some troubleshooting, errors like the “No Power to RH” error code usually indicate there is a problem with the wiring or the HVAC equipment.
