How to Properly set Aquastat for Summertime Hot Water Production?
I have an oil-fired steam system run with a Honeywell VisionPro 8000 with Redlink, utilizing a wireless equipment interface module. The system also provides domestic hot water utilizing an external holding tank with circulator, and an Aquastat L4006A controller.
The temperature on the Aquastat is currently set to 130, with a 10 degree differential. The boiler almost always fires whenever hot water is called for, and now that's it's warmer outside, we're noticing that some of the radiators are getting warm during the hot water call.
Should the Aquastat be adjusted differently? Could the way the Aquastat is wired to the equipment interface module have something to do with when the boiler fires for hot water (much more frequent than before the install of the Redlink system)?
Any advice and/or suggestions would be much appreciated. Many thanks and best,
