Pressuretrol PA404A Wiring — Heating Help: The Wall - I have a laars gas boiler that has 3 heating zones. I need to update the old mercury honeywell tstat on the 1st floor (warmth best) with a newer honeywell rth9580 wifi version. I've taken photographs of my whole gadget, categorised the wires in the snap shots to signify the associated connections, and protected the laars wiring diagram. There's a transformer hooked up on the wall close to the boiler this is stressed in-line to the system (electricity from the panel --> into the emergency boiler switch --> into the wall transformer --> then to the boiler (low water reduce off and boiler circuitry). There may be additionally a transformer in the boiler circuitry itself. Can someone tell me the quality approach (right preferred, not always easiest) to attach the c twine?. @ransomed_chicago , that four hundred appears to be about 9 oz of strain (the outdoor scale on that gauge. That is high-quality. Pegging is high due to the fact we do not know what the pressure became beyond 15 ounces. But, the boiler commonly may not run for forty five minutes until you operate set-backs. In any case, it seems like the pressuretrol is working. Regarding the 15 minutes on and off, do you have got a cyclegard low water reduce-off on that boiler that can be cycling the burner on and stale at intervals? What different controls are on the boiler. If the boiler shut down on some thing aside from pressure, that have to be understood too. Pressuretrol calibration query i did not but add the low stress gauge however i will tomorrow. Query approximately the dial interior. You can see in p.C that there are numbers from 1-five. Is that this the reduce out dial. It's far now close to 1. Does that mean it cuts out at a lower pressure? Fred i don't see the tiny hex head. Am i missing it or is that this pressuretrol one of a kind?. This site makes use of cookies to deliver our services and to expose you applicable commercials and job listings.

After changes, this honeywell steam pressure "pressuretrol" is now working because it need to. As air pressure is manually carried out thru a hand squeeze ball and the set factor is reached, a faint "click on" can be heard. It truly is the switch being turned off by the mechanism. As air is released and the stress drops, the ''reduce-in" set point is reached, indicated with the aid of every other soft click on.
