Old setup on antique boiler did not have a seperate control for circulator pump. this relay allows me to control gas valve and circulator seperately. Works great first time

Perfect Device for the application

By RJOPR

Comments about Switching relay with internal transformer, Dpst line voltage relays:

I used this item as a failsafe to shut down a de-humidifier in the event the condensate pump failed. I used the two class two switch leads to control the relay that contols the outlet to the de-humidifier. Now, if the pump fails, and the condensate trips the overflow switch, the de-humidifier outlet is de-energized...PERFECT!

R854A Switching Relay

By jcjflenz

Verified Buyer

Comments about Switching relay with internal transformer, Dpst line voltage relays:

Purchased this relay for my boiler to replace an ancient relay that had no provision for a zone control connection to the aquastat. Used the mounting space that the old relay occupied, and wired it up using shielded cable from a local supplier. Easy to read install instructions. Worked on the first try.

Great Price

Comments about Switching relay with internal transformer, Dpst line voltage relays:

I had the same product as part of my home heating system and it failed. So I wanted to purchase a new one and went to the local distributors and found their price was $50 more than your cost...It was a no brainer. If needed I will use your site and products again. I highly recommend you to anyone.

  • Switching relay with internal transformer, Dpst line voltage relays

    Q:

    I have a multi-zone oil baseboard heating system with five zones. Each zone has an RA845A and a circulator. The RA845A 1030 relay connected to one of the zones will intermittently kick on and off even when the thermostat for the zone is turned off.

    I think that it could be a bad relay but is there any other potential cause that should be checked before I purchase a replacement RA845A?

    Any guidance would be appreciated.

    Thanks

      A:

      Try switching the T-T wires and the pump wires with another zone, see if the
      problem stays with that relay or stays with that zone, in which case there
      is probably something going on the thermostat or its wires.

      I suggest that you replace the relay.

      A:

      You might want to double check the wiring to make sure nothing is wrong. If the wiring is all correct, the relay may require replacement.
