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
