Understanding the L8124E Triple aquastat relay
Hi I'm trying to get a customer Hot water. His Boiler isnt firing and I see no power is going to B1 and B2
Im used to the L8148E that when u power the control u have 24 volts on t and tv immediatley and when i put jumper on t and tv relay closes boiler fires and circulator comes on..
I assumed the L8124E works same way and when i got there i see power to control and nothing on T and Tv (or 1.8 volts) so i assumed control bad. I swapped out control and getting same result so now I question if Im understanding control correctly.
Any help would be greatly appreciated.
