Honeywell RA832A Hydronic Switching Relay

Nov 10, 2012 1 Replies

Hello,



Have 2 Honeywell RA832A Hydronic Switching Relays on a forced hot water residential furnace. Two circulators; no zone valves. Thermopile ignition.



Label has come off, so can't read the model number of one of them. One is the Honeywell 832A. No problem with this one.



The other is similar, but has the small slide switch on the top for power-out operation. (allows running between the high and low limits).



This is the one I need to replace.



Might anyone know what the model number might be ?



Probably an identical unit to the 832A, but with the slide switch



Thanks, Bob


Looking in a 2004 Honeywell catalog there were 2 controls that were rated for thermopile that had push to test switches. Don't know if that is the same as what you have. They were RA889A R8845U
