    How to troubleshoot a TemperZone Thermostat with no power LED on the main PCB?
    • J
      Judith JohnsonAug 19, 2025
      If the main PCB power LED is off on your TemperZone Thermostat, there could be several reasons. First, check if there is a loss of power to the main PCB and ensure the supply voltage is present. Also, inspect the PCB fuses for any failures. Verify that the 240V/24V switch is in the correct position. Finally, check if any other PCB LEDs are on, as the power LED itself might be faulty.

    What to do if my TemperZone TZT-701 Thermostat shows a fault when there isn't one?

      If your TemperZone Thermostat displays a 'Fault' message and the 'System OK' LED is off when no fault exists, it could be caused by several reasons. It might be that a device connected to the fault input has initiated a shutdown, so you should correct the fault from the external device. Another possible cause is the fault logic jumper (A/B switch) being in the wrong position, so you should change the fault logic switch position. Finally, check the fault input wiring for shorts on the Flt “A” fault input cabling.

    What to do if the TemperZone TZT-701 Thermostat temperature display seems inaccurate?

      Miss Donna Miller DDSAug 25, 2025
      If the temperature display on your TemperZone Thermostat appears inaccurate, it could be due to several reasons. Air from the wall cavity might be leaking into the rear of the thermostat, in which case you should plug any holes in the wall with tape to prevent leaks. Alternatively, external heat or cool sources like lamps, televisions, or drafts might be affecting the sensor's accuracy; move these sources away from the thermostat. If these steps don't resolve the issue, the sensor calibration settings may be incorrect.

    Why does the fan speed change frequently on my TemperZone TZT-701?
    • E
      Elizabeth DavisAug 26, 2025
      Frequent fan speed changes on your TemperZone Thermostat may not indicate a fault. Your TZT-701 thermostat is designed to automatically select the most energy-efficient fan speed based on the current conditions. If you prefer a constant speed, you can manually select a speed using the fan button.

    Why does the fan sometimes stop and start intermittently on my TemperZone TZT-701 while heating is running?
    • G
      Gregory PerezAug 28, 2025
      The intermittent stopping and starting of the fan in your TemperZone Thermostat during heating may not be a fault. Your air conditioning system could be running a de-ice maintenance function. During these events, the indoor fan is turned off to prevent drafts inside the building.

    What does the spanner icon on my TemperZone TZT-701 LCD mean?
    • B
      Brandy ShawAug 30, 2025
      The spanner icon on the LCD of your TemperZone TZT-701 thermostat indicates an internal fault. Communication loss between the main PCB and the wall controller should be strongly suspected.

    Why is my TemperZone TZT-701 Thermostat wall controller display blank?
    • J
      James WatersSep 1, 2025
      If the main PCB power LED is on, but the wall controller of your TemperZone Thermostat has no display, the issue is likely with faulty control wiring. Check the wiring between the wall controller and the main PCB to resolve this.

      Michael SolisSep 3, 2025
      If you see a spanner icon on the LCD of your TemperZone Thermostat and there is no equipment function, suspect an internal fault or communication loss between the main PCB and the wall controller. Ensure you are using screened cable. Check the wiring between the wall controller and the main PCB for shorts or open circuits, and verify that the wiring is correct.

    Why are there no heating/cooling outputs from my TemperZone TZT-701?
    • S
      Stephen MezaSep 5, 2025
      If your TemperZone Thermostat does not provide heating, cooling, or fan outputs from the relays, check the LED on the main PCB for the relay to ensure the TZT-701 is calling the function in question.

    Why can't I select heat or cool on my TemperZone TZT-701?
    • J
      Jaime McdonaldSep 8, 2025
      If you cannot select either heat or cool modes on your TemperZone Thermostat, it might be because the TZT-701 is set for heating or cooling only modes (Function “Fn” = C or H).
