If more than 12 Volts AC is present between RC and RH, then the transformers are NOT in phase. To correct this condition, reverse the secondary low voltage connections at either the Heating or Cooling transformer. Thermostat installation and all components of the control system shall conform to Class II circuits per t he NEC code.
