Microprocessor Controller

The standard chillers use a microprocessor-based PID controller. The Carel PCO controller is located in the control enclosure. The Carel PGD1 Interface is housed in a block of rigid plastic with a magnetic backing that allows the user to “stick” the interface on any metallic surface. The GP20 through GP50 units come standard with a 10 ft (3 m) cable, and the GP70 through GP210 units come standard with a 20 ft (6 m) cable. Longer cables are available through the After Market Sales Group. The controller is factory set and adjusted; no field adjustment to the internal controls is necessary. The standard operation range is 20ºF to 80ºF (-7ºC to 27ºC).

Warning! Operating the chiller setpoint below 45°F (7°C) without the proper amount of glycol for freeze protection could result in a damaged evaporator. ACS Group does not warrant the freeze up of the evaporator under any circumstances.
