Heating boiler aquastat control diagnosis, troubleshooting, repair on controls like the Honeywell R8182D Combination Control Aquastat. 1. Turn thermostat down -. Turn the wall thermostat all the way down so it is not calling for heat. 2. Check incoming voltage -. Using a DMM or VOM check for line …
How can I tell if my aquastat is calling for heat?
Check thermostat switch terminals: Now turn the Thermostat all the way UP so that it is calling for heat (remember to set it back down later). You should see 24VAC on BOTH of the thermostat or TT terminals inside the aquastat.
