How to wire T-100-H

The device uses standard thermostat connections: C, R, W1, W2, Y1, Y2, G.  The use of each of these terminals vary by application.  The most common applications are outlined below; for applications not found on this list, please contact Evolve Technical Support for more detail.
 
Fan Coil:
 
  • C = common
  • 24RC/24RH = 24VAC – either terminal may be used, as there is in an internal jumper on the circuit board connecting the two.
  • W1 = heating
  • W2 = only used in a 3 speed system, this terminal represents MEDIUM fan
  • Y1  = cooling
  • Y2 = only used in a 2 or 3 speed system, this terminal represents HIGH fan
  • G = LOW fan.  Note: in a 1 speed system, the G terminal is the default “only” fan terminal used
 
Heat Pump:
 
  • C = common
  • 24RC/24RH = 24VAC - either terminal may be used, as there is in an internal jumper on the circuit board connecting the two.
  • W1 = auxiliary electric heat, if applicable
  • W2 = change-over (reversing) valve.  This terminal is typically wired to the “B” or “O” terminal on the HVAC unit.  Note, by default this terminal is energized in cooling, but can be configured to engage in heating instead. 
  • Y1  = compressor, used for both heating AND cooling
  • Y2 = Represents HIGH fan, if applicable
  • G = LOW fan.  Note: in a 1 speed system, the G terminal is the default “only” fan terminal used
