Honeywell R8335A Replacement
Does anyone have a recommendation to replace a Honewell R8335A multizone hydronic relay panel. I have three zones, each with a circulator pump and Honeywell zone valve. Thanks
A zone valve and a circulator on each zone? For a total of three zone valves and three circulators?All Steamed Up, Inc.

Yes, three circulator pumps and three Honeywell zone valves.0
Flow checks...the hard way..?Steamhead said:

Is there a typo in your description ( R8335A?)
What problem are you having with the panel/system?
I have a customer with relay, a contactor, zone valve and circulator for each zone....aka yikes!
No flow checks. There was one that was decaying and a plumber replaced it a zone valve (the third on the system).
No typo. Honeywell R8335A Multizone Hydronic Relay Panel. Hot water zone keeps shutting off. I have had to re-solder the circuit board multiple times in last several years. I would like to replace the relay panel.0
I just looked up the pdf. So where/how are the zone valves connected? This zone controller is basically the Taco 503, but you add the transformer.
I guess you are using the transformer for the thermostats AND the zone valves, and the end switches are wired to the panel. What's the rating on the transformer?
I suspect this is why you are doing some re-soldering.
do you actually need the zone valves.steve0
