Is this right? One heat zone (thermostat) seems to govern the other three
I have a four zone heat system with a Burnham gas forced hot water boiler to baseboard radiators. I can't get the other three thermostats in my home to call for heat unless the 'main' thermostat (the one that controls heat/cool/fan) in the Master Bedroom calls for heat. I have almost no experience with this type of heating system, but that seems to defeat the benefit of multi zone heating as the heat in our master bedroom needs to be on if we want heat in the living room, office, or guest rooms.
All four thermostats are Honeywell dials. One of the 'slave' thermostats is simply R/W two wire and green wire was capped off. Haven't checked the 'master' thermostat yet.
I discovered this quirk when I upgraded one of the dials to a programmable thermostat. Couldn't get the new stat to call for heat. Thought it was a wiring problem until I noticed I couldn't get the remaining two 'slave' dials to call for heat either unless heat was on in Master bedroom. With heat in MB on, dials and new programmable works.
Is this one of those 'not a bug but a feature' type deals?
