Why is my Honeywell B/Q682 not producing heat?
- S
  Steven WilsonAug 18, 2025
  If your Honeywell Thermostat isn't producing heat, there could be several reasons. First, check that the system switch is in the HEAT position, not OFF or COOL. Also, inspect the fuse or circuit breaker; replace the fuse or reset the breaker if necessary. Ensure the furnace power switch is set to ON, and if your furnace has a pilot light, make sure it is lit according to the manufacturer's instructions. Finally, turn off the power to the furnace and check the R and W thermostat connections, looking for correct terminal hookups, frayed or broken wires, and loose terminal screws. After addressing any issues, turn the power back on.

  If your Honeywell Thermostat isn't cooling, the system switch might be in the OFF or HEAT position; move it to COOL. Check the fuse or circuit breaker and replace or reset if needed. Ensure the condenser switch (located outdoors) is in the ON position. Finally, turn off power to the cooling system and inspect the Y and R thermostat connections for correct terminal hookups, repairing any frayed or broken wires and tightening all terminal screws.

What to do if the Honeywell B/Q682 Thermostat room temperatures are not correct?
- C
  Carl MooreAug 23, 2025
  If room temperatures are incorrect, reset the thermostat setpoint levers to the desired temperatures. Also, check the position of the subbase system switch (on heating-cooling models) and move it to the desired operating position.

What to do if the Honeywell Thermostat rooms do not warm up at programmed time?
- S
  Stephanie LunaAug 26, 2025
  If rooms do not warm up at the programmed time with your Honeywell Thermostat, the timer program for the heating system may need more time. Try moving the red pin one-half hour earlier on the program dial.

Why do Honeywell B/Q682 Thermostat setting and thermometer reading disagree?
- T
  Tonya AllisonAug 28, 2025
  To address incorrect readings between your Honeywell Thermostat setting and the thermometer, reinstall the thermostat subbase using a spirit level to ensure it is level. Also, consider drafts or radiant heat in the area around the thermostat. The thermostat should be about 5 ft (1.5m) above the floor on an inside wall; contact a qualified service technician for relocation if needed.

What to do if the Honeywell B/Q682 Thermostat room temperatures are still not correct?
- S
  samuel83Aug 30, 2025
  If room temperatures are still incorrect, for a heating-only system, move the temperature setting levers 5°F (3°C) above room temperature. For a cooling-only system, move the levers 5°F (3°C) below room temperature. For a heating/cooling system, with the system switch at HEAT, move the levers 5°F (3°C) above room temperature to start the heating system. With the system switch at COOL, move the levers 5°F (3°C) below room temperature to start the cooling system.

Why is my Honeywell B/Q682 timer losing time?
- A
  Amy BoothSep 2, 2025
  If the Honeywell Thermostat timer is losing time, ensure the power is on. If the clock is powered through the system transformer, a high limit control might be cutting power on safety; in this case, wire a separate transformer to power the clock. Also, a clogged filter might cause the safety limit on the equipment to cut off power; replace the filter and reset the clock.

What to do if Voltage at Honeywell B/Q682 Thermostat Timer Terminals is 0 Vac?
- J
  James BlairSep 10, 2025
  If you measure 0 Vac at the timer terminals, it could be due to several reasons. First, ensure the system power is on. If the power is on, there might be a short in the timer power supply wiring, which would require replacing the wiring. Another possibility is that the limit switch contacts are stuck open, requiring you to free or replace the limit switch. Lastly, the transformer supplying power could be burned out, necessitating a replacement of the transformer.
