(1) The low ambient cut-out is fixed at 14°F or 17.6°F if fan speed inhibit is in effect on units with two speed
fan options in the heating mode.
(2) The minimum discharge pressure allowed with any fans running is approximatly 240 psig
i.e. Fan Control On Pressure - Fan Differential Off Pressure is not lower than approximately 240 psig
The Discharge Fan Differential Off Pressure high limit is lowered to prevent going below approximately 240 psig
based on where the Discharge Fan Control On Pressure is programmed.
(3) Defrost termination temperature is fixed at 46°F.
(4) Programmed on site to match glycol concentration and site requirements
(5) Programmed to match number of compressors
(6) Programmed to match number of fans
