Note 1: Optional Connection for Heating Stage 2 operation, Thermostat "Y2"
option must be configured as "Y2 - Off".This configuration uses the
compressor only for 1st stage heating and compressor plus auxilliary
heat for 2nd stage operation. The thermostat is configured as a two
stage heat / one stage cool thermostat for single speed units with
PSC fan and backup heat. For two-stage units with backup heat or
units with ECM fan and backup heat, a three stage heat / 2 stage
cool thermostat is required.
