    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.
