Comments about Honeywell Aquastat Relay, 8°F differential:
I have a 25 year old boiler and after troubleshooting, found the Aquastat relay and gas valve were shot. I searched locally and found supply houses were not helpful as the model was old and had been replaced and I could not get a straight answer. I contacted Pex Supply after doing an online search and they cheerfully gave me the correct model replacement and the best price I could find online!! The only complaint was that the online chat to get the info on a replacement took nearly 3 days to hear back from. In the meantime I was without heat, so on day 2 with no response, I chose to call their toll free # and got an immediate answer. Thanks Pex!!!!

Comments about Honeywell Aquastat Relay, 8°F differential:
I had to replace this aquastat after 36 years due to burned contacts on the relay for the circulator pump. It is an exact replacement which is now working perfectly. How often do you get 36 years out of a part and find an exact match?

Q:
I just had my Honeywell Aquastat Relay L8148E replaced with the L8148J. Apparently this is the direct replacement since the L8148E is discontinued (according to the Honeywell web site). The boiler comes with the automatic vent damper. My HVAC guy replaced the Aquastat and connected the wires just like the old one. However the boiler did not work properly. Even when the thermostat did not call for heat the boiler would still turn on. After some trouble shooting, my HVAC guy told me that it appears that the new Relay L8148J must have some internal ground, and the ground (green wire) that goes from the burner (screwed on the burner) to the GDN (Burner) on the Module (black box on the boiler) was causing this problem. When he disconnected the green wire (GDN burner) everything seems to work just fine. Is this true? Do the L8148J have some internal grounding that would cause this problem.

The person in Colorado (see above) appears to have the same problem.

CUSTOMER CARE

A:
The L8148E is still available with a vent damper plug. If you are experiencing issues with the L8148J that was installed, we recommend replacing it with either the L8148E1257 or the L8148E1265, both which are still available.

Q:
Can Aquastat relay L8148J replace Aquastat relay L8148E?
Our plumber told the electrician it was OK to take out the L8148E and replace it with the L8148J. They are working on it now and have high over heating and high pressure and trouble shooting. Adjusting the temp indicator does not have any effect, temp just keeps going up super high. A licensed/union plumber and licensed/union electrician. They thought it would be no problem, since they had the aquastat L8148J on hand. I think they need to get the exact model# aquastat that they took out.

A:
The difference between the units is that the "E" model has an operating range of 180 to 240 degrees and a temperature differential of 15 degrees, while the "J" model has an operating range of 120 to 240 degrees and a temperature differential of 8 degrees. It sounds like some temperature setting may need to be changed.
