Single-Circuit Units; Dual Circuit Units; Appendix B − Control Modes With Humidi−Mizert System And Economizer - Carrier 48/50PG C03-14 Operation And Service Manual

Thermostat input shown for cooling demand (versus temperature
sensor and set point).
dehumidification demand (versus relative humidity sensor and set
point). Economizer cooling availability is dependent on
temperature or enthalpy.

SINGLE-CIRCUIT UNITS

(Thermostat Control Type configuration is ignored)

DUAL CIRCUIT UNITS

1-Stage Y1 (Thermostat Control Type configuration = 1)
and 2-Stage Y1 (Thermostat Control Type configuration = 2)
DUAL-CIRCUIT UNITS
Digital (Thermostat Control Type configuration = 3)
Circuit Subcooling mode = REHEAT 1
for
Circuit HGRH mode = hot gas reheat = REHEAT 2
Circuit ON mode = normal cooling
Thermostat Control type configuration = 0 = Adaptive, or Unit
Control Type configuration = 3 = Space Temperature, for
Dual-circuit and Tri-Circuit units results in added staging timers
and flex between 1-stage Y1 and 2-stage Y1.
