Honeywell L8148E and logamatic 2107
I installed a Buderus G124 with a 2107 control, system has 4 zone valves running off taco zone valve control box. Domestic is of in the 2107 it is heating only. Boiler has been running for 2 weeks until Friday night. I found no power from B1 and B2 on the L8148E so I replaced it, boiler ran for 8 hours and now no heat again. I called Buderus but haven't heard back any suggestions Thanks
Has the factory installed jumper been removed between terminals 10 & 12 on the 2107?Bob Boan
You can choose to do what you want, but you cannot choose the consequences.0
We changed the L8148E again and found the Field vent damper board burned out. Left vent damper open with jumper in the L8148E. Haven't heard from home owner so thats a good thing. Going back this morning to changeout the damper motor. 2 nights of no sleep not a good weekend. Thanks0
