Hi Joe,
I purchased this to replace the one that's presently installed on my boiler.
I will be installing it with other multiple parts that I ordered from you before the
heating season as maintenance and an upgrade to my heating system.
It is an excellent product from a great company. You offer quality products at a good
price with friendly customer service and fast delivery times. You are also a great company. Many thanks.

Yes I would buy again and I have
Well after replacing about 7 of these none of which was the fault of the product or supply house May I add. I think we found the problem . I had surge protectors on my box . I had a de dedicated ground at the unit . Was turning the breaker off as my phone would tell of lightning storm coming in area . Still this last time it fried this cutoff. Upon inspection More we found that the ground coming from the fire safety switch on the ceiling and going into my shut off switch at the burner was nipped right at the BX used . They were using the BX as ground and the way the box was fasten to the side of the furnace was lose So we believe it had a crummy ground my contractor was not as good as I thought at the time the house was built

Good buy for an inline voltage low water cutoff.
Works exactly as expected. Installed into a radiant floor heat circulation system as a low water cutoff. Easy to install and wire. Bought because I have everything wired inline with standard voltage and don't have any low voltage controls. No issues on testing and startup and has been running flawlessly for a month now.
In floor heat is awesome.

Product Q&A
1 Question1 Question
Q: Looking at this to pair with a Peerless PF-110. The PF-110 has a built in service switch, so it seems that a separate shutoff switch is not needed. But the RB-122E schematic calls for it to be wired into an external switch. Is there a way to wire it on the PF-110, or does a separate power switch need to be added? Thanks!

Doesn't the PF-110 have it's own sensor to detect a lack of supply water? The RB-122E is intended to be tied into the "Burner Shutoff switch" which is usually located outside the boiler room or at the top of the basement stairs when the oiler is in the basement. I might guess your PF-110 would still require a Burner Shutoff Switch beyond the unit's internal power switch. Good luck.

The RB-122 is power by 120vac and the dry contacts get connected to the terminal board labeled for LWCO so if you take the source from the TB you have a switch controlling it from the equipment Sent from my iPhone
