Questions and answers
I had a static electricity arc when I was setting the temperature. Now the screen is faint and I can barly see the numbers. Did the arc damage the screen and should I replace the thermostat?
A static electricity arc can potentially damage the screen of the Pro 1 IAQ T725 thermostat if the discharge affects internal electronic components. If the screen is unresponsive, flickering, or displaying distorted images after the static discharge, it is likely damaged.
To determine if the thermostat should be replaced:
1. Power Cycle – Remove power for a few minutes and reconnect to see if the issue resolves.
2. Check for Physical Damage – Look for visible burn marks or discoloration.
3. Test Responsiveness – If the screen remains unresponsive or malfunctioning, internal components may be damaged.
If the thermostat does not function correctly after these steps, replacing it is recommended.
