SMART CONTROLLER
INTRODUCTION
The smart controller is a parametric controller for the complete management of air conditioners. All settings
are pre-programmed at the factory. Cooling setpoint, cooling differential, high/low temperature alarm setpoints,
and door open and/or smoke detected switch can be adjusted by the user. Alarms are outputted through a relay
contact.
NOTE: The polyester tape on the topside and the neoprene seal around the connectors
assure IP34 rating protection for the controller. DO NOT REMOVE.
ENERGIZING THE CONTROLLER
The controller is wired and pre-programmed at the factory to be energizing when power is applied to the air
conditioner. The controller will default to the standalone operating mode when initially powered on. Master/Slave
operating mode is optional and will require additional setup.
CONTROL STATUS INDICATION
The display has numerous symbols that indicate if the controller is heating, cooling, alarming; if the compressor
is enabled and if the ambient fan is enabled. The 3 alpha-numeric characters further describe alarms and show
the cabinet temperature by default.
NOTE: The Slim Fit air conditioners DO NOT come standard with a heating option.
