HEAD PRESSURE CONTROL
The 48TJ004-014 and 024 standard units are designed to operate in cooling at outdoor temperatures
down to 25 F, the standard 48TJ016 unit operates down to 40 F, the standard
48TJ020 unit operates down to 35 F; and the standard 48TJ028 unit operates down to 48 F.
With accessory Motormaster (48TJ004-014) control (condenser-fan speed modulation),
Motormaster II control (condenser-fan cycling for units sizes 004-014), −20 F low-ambient kit
(condenser fan sequencing for 48TJ016), or Motormaster III (48TJ020-028) control (condenser
fan speed modulation) units can operate at outdoor temperatures down to −20 F.
The head pressure controls, which mount in the condenser section, control the condenserfan
motor to maintain correct condensing temperature. Refer to Price Pages or contact your
local Carrier representative for appropriate accessory combinations for desired outdoor ambient
temperature operation.
