I just recently installed a Taylor 9940n thermometer on my boiler line before the heat exchanger to monitor the temperature coming in from the boiler. My understanding is that this unit can be used to turn on and off different controls. What I would like to do is set up the thermometer so it can sound a buzzer when the input temperature falls below or goes above the temps that I usually run the water at. In looking at the manual it appears this should be possible but with my limited electronics experience I have not idea what components I need or how to set this up. Any advice or can someone point be in the direction of the components I would need?
