Table 16 — EconoMi$erIV Input/Output Logic
*For single enthalpy control, the module compares outdoor enthalpy
to the ABCD set point.
†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).
