This thermostat is designed to operate a
single-transformer system. If you have a two-
transformer system, cut and tape off one
transformer. If transformer safety circuits are
in only one of the systems, remove the
transformer of the system with NO safety
circuits. If required, replace remaining
transformer with a 75VA Class II transformer.
After disconnecting one transformer, the two
commons must be jumpered together.
