ply external power to these terminals under any circumstances. To avoid this
problem when using zone valves, disconnect field wires from 40200 or 42230
thermostatterminals.Thenconnectavoltmeteracrosswires.Operateallzones
andverifythatthereisneveravoltagereadingatthemeter.Avoltagereading
indicates incorrect wiring that must be corrected before attempting to operate
the burner.
