Honeywell Aquastat L8124A
Posted by gillric on October 07, 2002 at 12:42:38:
Every time the aquastat calls for the boiler to start and heat the water, the circulator starts regardless of thermostat settings. Disconnecting the lead wires at the aquastat results in the same. Is there a test I can perform at the aquastat to isolate the exact problem with it? I don't mind heating the tankless coil for hot water useage, but the summer has been hot enough this year without the baseboard contribution!
