  1. I have a Honeywell HZ432 Truezone control panel. Zone 3&4 lights are blinking, indicating a short. How do I fix? Are there zone breakers within the system?

  2. I have a HZ432 trueZone Honeywell.
    The control panel indicates the temp going up to 153 pumping heat. Then starts to go down and when it is about 54 I believe should start to go up again, but keeps going 54 to 55 and 55 to 54 for a minute and a msg shows surge override? if I don’t do anything stops, if I press next then it will starts again and goes up pumping heat.
    Seams to me that during the day works most of the time but during the night with a cold weather totally stop and I have to reset again.
    Do you have any idea as what I would have to do?

    Thanks a lot.

  3. I have a HZ432 on a geothermal system (3H 2C)..

  5. My honeywell truezone HZ221 is not even lit up at all. My unit was working last week. I turned it off by the thermostats and when I went to them back on yesterday nothing would happen. Nothing would come on

  6. I have a Honeywell HZ 432 true zone . This winter the upstairs heat stays on even when the set temperature is satisfied the upstairs damper seams to be opened when the downstairs zone is calling for heat both zones are open.
    When the heat pump is set for A/C the downstairs is open all the time, so downstairs is always cold with A/C & upstairs is always Hot with the furnace or heat pump.
    Wondering if it’s the control is a damper issue.

  7. I have the Honeywell HZ322. It appears our Air Conditioning System has failed. I’m trying to test the system, but none of the buttons on the front seem to be working. They worked at first, but now they do nothing. The A/C worked when in the Test mode when the buttons worked, but now I can’t get anything on the panel to work. I am using it with a Honeywell FocusPRO 6000 Series programmable Thermostat with battery back up. Do I need to do something with it to restore the HZ322 so it will operate?
    Also, the “Emergency Heat” light is on constantly. The system is being used with a Train Heat Pump.

    Does anyone have some suggestions? The temperature outside has been around 100 degrees. The system is less then a year old. This happen last year and we had to replace the condenser and the Heat Pump. I have the upstairs Zone 2 turned off. Please help. It’s still 100 degrees outside.

  8. Problem with AC unit. I have the honeywell HZ322 controlling 3 zones using the honeywell focuspro th5000 thermostats. Downstairs which is on one’s own doesn’t respond to the thermostat keeps getting hotter and hotter and will not cool. Master bedroom on another zone keeps getting colder and colder with the thermostat turned off. It seems like the damper is staying open in the master bedroom and not opening in the downstairs. My guess its the hz322 but I do not know how to troubleshoot it. Out of the three zones to have a red LED and one is green. I do not have a manual to program or troubleshoot that unit. Please help

  9. I installed a HZ332 TrueZone control board. Both zones are calling for emergency heat, but the board will not send the emergency heat signal to the equipment. Any ideas why. Could I have missed something during setup?

  12. I have a Honeywell hz322 3 zones my 3 zone is upstais blower comes on and runs when set point is75 and room temp is 70 to 72. I changed the thermostat but blower still runs upstairs on 3 zone.

  18. This is the second HZ432. It has worked well for four years. For no apparent reason it turns on the blower, and 3 of the four zone lite’s red indicating a heat call but does not light burner. It stays that way until power is shut off for several hours, powers back up and works for several days normally, than returns to this state. As I recall the older unit did the same thing. Zone thermostats are all set to off.
