In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
System seems to work normally @ 70 degrees and 0 psi. (pressuretrol is set @ 0.5 low + 1.0 high). When I raise temperature to 72 degrees, the pressure rises to 2.25 lbs. - temperature @ 72 degrees, and boiler goes off. When pressuretrol drops to approximately 0.5 lbs. the boiler comes back on, and pressuretrol goes to 2.25 lbs. - boiler then goes off - temperature remains @ 72 degrees. This sequence will repeat until temperature reaches 73 degrees - then boiler goes off. It seems as though the pressuretrol is the problem? Maybe the Honeywell thermostat sensitivity is off? What am I missing here ?
