Chances are it's a bad daamper. You can bypass any tstat by wiring red green and yellow together. Bypass the tstat, if still blinking you'll know it's the damper. You can then swap that damper to another zone and be sure the new zone then starts flashing.

Im assuming that--
you waited long enough for the valve to open
you used the manual lever to check for flow
same thermostat
boiler isn't off on reset
theres power to the boiler
Do you hear the valve energize? If not--
The orange wires are interchangeable so it dosnt matter. the zone valve is normally closed so it wont open unless it gets power from a call for heat. Follow the blue and brown wires down to the control and make sure they aren't cracked. Check for water in control panel. Pull relay and look for small soot mark inside (blown).If wires have been spliced at any point remove wire nuts restrip wire and use NEW wire nuts to reconnect.At control remove wires one at a time clip and strip and reconnect. make sure the wire is wrapped around screw and tighten. If valve still isn't opening check the corresponding TT terminal connections clip and strip and reconnect.Still no water? With wires removed jump the TT terminals. If it powers after at least 15 sec then it may be either you thermostat or the wire going to it.
It could also be on the water side. If the plunger inside the valve body is stuck closed or clogged you can either isolate and drain the zone, remove the brass plug and dig around or buy a zone valve WITH the brass body. isolate and drain the zone, sweat off the old one and sweat on a new one. I know...good times :-{

Blinking amber light indicates a shorted or tripped damper motor circuit. I would check to see if there's power to the damper motor if there is check to see if damper is jammed and not allowing full motion of damper. If there isn't find out why and restore it. Then test zone for proper and full motion.

Get it serviced. If a service switch has tripped there may be a component failure or circuit issues. Also, gas boilers are required by law to be inspected and serviced annually so if your service light is on or it's overdue for a service, only a licensed tech can service it.

So is the unit running ? Hz311 is a zoning board, how about your tstats, is air blowing in the rooms with the tstats when the unit is running?

Honeywell... | Answered on Jan 26, 2019


Pull power or battery from the thermostat, then restore power. If you get the same display, the thermostat is bad and will need to be replaced. It is not a hard job, just note what color wire is attached to which terminal, and install the new one the same way. It doesn't have to be Honeywell. You just need to know what is being controlled. Is it for Heat only, or A/C only, or A/C and heat, or a heat pump.

More information is needed to be certain: What is the Interterm model number? What terminals were the wires connected to on the interterm, wire color and terminal ?
