Honeywell Relay

for Hydronic Applications with typically SmartValve applications because of the 50 VA transformer as that is part of the control center. The RA832A-1066 will not therefore replace it. If the transformer is okay on the R8285 then just replace the relay which is an R8222F. Or you can put a seperate 50 VA transformer and rewire the terminal board on the R8285 if the transformer is the problem.

    I have a customer who wants to know if he can use a RA832a-1066 in place of a R8285D5001. I am not sure what the difference would be.He is using it for a secondary pump control and 2 zone valves.
