FUNCTION
• -9˚F Low ambient cooling operation using Low ambient kit and hood with damper
(Analog output 0~10V)
• Demand control
DESCRIPTION
• Low ambient kit supports -9˚F cooling operation by making stable condensing
pressure with reducing air ow rate from hood and damper control given 0~10V
proportional to condensing pressure.
• Low ambient kit provides IO Module function.
• The appropriate Low Ambient Bafe Kit is a required accessory.
• Transformer and terminal block are included.
