How to troubleshoot if heat does not turn on when 'Heat On' is solid on my Honeywell TB7100A1000 MultiPRO Thermostat?
- M
  Michael GuerreroSep 2, 2025
  If your Honeywell Thermostat displays Heat On solid, but the heat isn't turning on, it could be due to heating equipment failure. Check for 24 Vac at the equipment on the secondary side of the transformer between power and common. If voltage is not present, check the heating equipment to find the cause of the problem. Check for 24 Vac between the heat terminal (W) and transformer common. If 24 Vac is present, the thermostat is functional, so check the heating equipment. Another potential cause is a loose or broken wire connection between the thermostat and heating equipment. Check for 24 Vac between the heat terminal (W) and transformer common. If voltage is not present, check the wire connection between the thermostat and the heating equipment.

Why temperature settings do not change on my Honeywell TB7100A1000 MultiPRO?
- D
  Dr. Francisco DunnAug 29, 2025
  If your Honeywell Thermostat's temperature settings are not changing, it could be due to reaching the upper or lower temperature limits. Check the temperature setpoints and modify ISU 0600 and 0610 as needed. Alternatively, the keypad might be fully locked. Check ISU 0670 to change the keypad locked options.

  lori40Aug 28, 2025
  If your Honeywell Thermostat is calling for heat or cool, but nothing is happening, the heating or cooling equipment might not be operating. In this case, check the wiring and ensure the correct system type is chosen in ISU 0170. You can also verify the equipment operation in System Test mode.

How to fix a Honeywell TB7100A1000 MultiPRO when the display does not come on?
- A
  Andrew McmahonAug 26, 2025
  If your Honeywell Thermostat display doesn't turn on, it could be due to a lack of power. Check for 24 Vac between C and Rc. Also, ensure that the AAA batteries are correctly installed and have sufficient charge.

Why cooling does not turn on when 'Cool On' is solid on my Honeywell TB7100A1000 MultiPRO?
- C
  carolyngilmoreAug 25, 2025
  If your Honeywell Thermostat shows 'Cool On' but the cooling doesn't turn on, it could be due to cooling equipment failure. Check for 24 Vac at the equipment on the secondary side of the transformer between power and common. If voltage is not present, check the cooling equipment to find the cause of the problem. Also check for 24 Vac between the cool terminal (Y) and transformer common. If 24 Vac is present, the thermostat is functional, so check the cooling equipment. Another possibility is a loose or broken wire connection between the thermostat and cooling equipment. Check for 24 Vac between the cool terminal (Y) and transformer common. If voltage is not present, check the wire connection between the thermostat and the cooling equipment.

Why is my Honeywell TB7100A1000 MultiPRO not turning on heating or cooling?
- G
  ginaleeAug 22, 2025
  If your Honeywell Thermostat is not turning on the heating or cooling, it might be due to the thermostat's minimum off-time being activated. Wait up to five minutes for the system to respond. Also, ensure that the system selection is set to Heat or Cool, and verify that the system type selection in ISU 0170 is correct.
