LARK standard controller provides unit control for heating, cooling and ventilation utilizing input from indoor and outdoor sensors. Quality and reliability are enhanced through the smart control and logic for:
Anti-short cycle timer prevents the unit from short cycling, considerably improving compressor life
Optional soft start avoids electrical “spikes” by using staging on fans, compressors and heaters
Interoperability with Modbus protocol allows to integrate with BMS for outstanding control benefits
Automatic lock out system on failure and reset by interruption of power supply.
Automatic defrost
Compressor lead-lag operation to ensure longer life for the compressors and equal running hours between compressors
External remote ON/OFF button for remote operation of the unit using external ON/OFF switch or connection to BMS
High and low pressure safety switches (capsule type, factory Pre-set)
Remote control panel with the same functions as the on-board panel at a distance of 20 m as standard
