    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?

    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.

    I have a HZ432 on a geothermal system (3H 2C)..
    When I pushed the electric heat button on the zone panel the unit turned off.

    I have a Honeywell HZ432 Dual Zone; One zone and thermostat up and 1 zone and thermostat down. The upstairs heat is running away. Technicians came in but said they couldn’t work on dual system but they did say that most likely a baffle was stuck. Is there something I can do to fix myself or will it require a technician. This is the third time this has happened in 4 years and is getting expensive.
