Microprocessor-based Carel uC2controllers are integrated into the company’s dual circuit portable chillers and single circuit central chillers. Also, Carel pCO3controllers have been integrated into the company’s dual circuit central chillers. Both controllers are designed specifically for chiller applications and reach their process temperature with good control performance. The uC 2control has an LED readout of setpoint and process fluid temperature. The pCO3controller has a programmable LCD touchscreen display with industry-standard graphic symbols to indicate modes of operation and system performance.
