Aquastat - Oil -Gas Boiler Interchangable?
Hello - I have a Crown CXE-5 (1997 vintage) gas boiler (150k BTU/HR, not high effiecency). I recently noticed the Honeywell L7224U1002 Aquastat a tech installed over a year ago is specified for use it oil boilers. Should I be concerned? My mechanical aquastat had failed.
Also, when scrolling through the digital settings on the Aquastat I noted the low temp cutoff is turned off. Is this correct? The high point is 199 and the differential is 10. I have 4 zones serving 3 baseboard loops and an indirect DHW tank. One circulator. I live in the northeast. I had the unit cleaned/inspected last fall with no issues. I have read some threads,with no firm conclusions, regarding cold start vs maintaining the boiler warm. I should note that the boiler temp never seems to exceed 140 and can linger in the 110 -120 range for very long periods in the winter (likely related to my system's inability to maintain the house temp during the winter).
