COOLING STAGE 3 DELAY
Delay after stage 2 for cool has been active. Turns on 2nd stage of cooling
when economizer is 1st stage and mechanical cooling is 2nd. Allows three
stages of cooling, 1 economizer and 2 mechanical.
OFF = no Stage 3 cooling
SD DMPR POS CLO CLO or OPN
Function NOT AVAILABLE with 2-speed mode
Indicates shutdown signal from space thermostat or unitary controller. When
controller receives 24 vac input on the SD terminal in conventional mode, the
OA damper will open if programmed for OPN and OA damper will close if
programmed for CLO. All other controls, e.g., fans, etc. will shut off.
DCVCAL ENA MAN
MAN (manual)
AUTO
Turns on the DCV automatic control of the dampers. Resets ventilation
based on the RA, OA, and MA sensor conditions. Requires all 3 RA, OA, and
MA sensors.
For single speed units only.
