Pro1 T855 Thermostat Troubleshooting Guide

The Pro1 T855 is one of the most popular thermostats available today. It’s easy to use and reliable in managing temperature levels throughout your home. However, like any device, it can occasionally experience performance issues or even break down entirely.

Let’s get to the Troubleshooting Guide:

Check The Batteries

Did you know that 99% of thermostat breakdowns are due to low or dead batteries? It’s true! So, if your pro1 t855 thermostat isn’t working properly, the first thing you should do is check the batteries.

First, make sure you have two good batteries in place – 3V lithium CR2450 or equivalent replacements work best for this model. If there’s no voltage measuring on your multimeter when testing the battery terminals then it’s time to replace them.

Make sure to use a soft cloth and alcohol-based cleaner when swapping out the old ones for new ones. Then be sure to test each terminal with a voltmeter before installing back into the device.

Don’t forget to also inspect the wiring connections in case they need tightening or replacing too. Taking these precautions will help ensure your thermostat runs smoothly and efficiently.

Reset The Thermostat

Resetting your Pro1 T855 thermostat is a quick and simple way to resolve common issues.

To do this, you can either go to your circuit breaker box and flip off the switch labeled “HVAC” or “AC,” then wait 30 seconds and turn it back on.

Alternatively, you can install the batteries backward, wait 5-10 seconds and then reinstall them properly. Your thermostat should now be reset and working properly.

Clean Your Thermostat

You would think that troubleshooting a thermostat wouldn’t require much of a clean up job, but actually it does.

Here are some tips on how to properly maintain and clean your thermostat:

  • Check for debris – Dust and dirt can collect in the crevices around the buttons or edges of your thermostat. Make sure you use an air duster or brush to remove any accumulated dust or dirt.
  • Wipe down with soft cloth – Use a microfiber cloth dampened with water (or mild detergent) to wipe away any smudges or sweat marks from the surface of your thermostat. Do not spray nor pour liquid directly onto your device as this may damage its internal components.
  • Use compressed air – If there is debris lodged inside vents or ports, use compressed air at low pressure to blow it out. Be careful not to put too much pressure when doing so as this could cause further damage.
  • Replace batteries regularly – Batteries should be replaced every 6 months, depending on usage patterns and climate conditions in order for your unit to remain reliable and efficient.
  • Keep away from heat sources – Your thermostat should never be placed near any type of heat source such as stoves, radiators, fireplaces etc., since this will affect their accuracy and performance.

Inspect The Wiring

First, check to make sure all connections have been properly fitted and secured. If not, you’ll need to reattach them or replace a loose wire before proceeding further.

Also take a look at any exposed wires for signs of damage such as fraying or corrosion.

Next, test the voltage coming from each connection point using an appropriate tester. This will help you determine if there is a short in the system that could be causing problems with your thermostat’s operation.

Finally, use a continuity tester to verify that electricity is flowing freely through all the connections and cables between components in order to ensure proper functioning of your thermostat systems.
