*For single enthalpy control, the module compares outdoor enthalpy to the ABCD setpoint.

Power at N terminal determines Occupied/Unoccupied setting: 24 vac (Occupied), no power (Unoccupied). ** Modulation is based on the supply-air sensor signal.

†† Modulation is based on the DCV signal.

*** Modulation is based on the greater of DCV and supply-air sensor signals, between minimum position and either maximum position (DCV) or fully open (supply-air signal).

††† Modulation is based on the greater of DCV and supply-air sensor signals, between closed and either maximum position (DCV) or fully open (supply-air signal).
