Unit Description 5-9
Electric Operation (Model 50 Only)
During electric operation, the operating characteristics of the system are basically the same with the following exceptions:
• If the host unit (front) and remote controllers are both calling for Low Speed Heat, the host unit will shift to Null, the electric
motor will stop and the unit will not operate. The host unit will stay in Null until one (or both) of the controllers calls for High
Speed or until Defrost is initiated by one of the compartment control systems.
The mode of operation charts on these pages show the modes of operation that result from various combinations of controller and
defrost demands.
