To change from heating to cooling or cooling to heating, tap the mode select

button. Set the desired loop water temperature by tapping the up or down button. The

system will provide cooling or heating as selected.

Operation

The control will automatically operate the circulating pump, sea water pump,

compressor and heater or valve as necessary. Inlet temperature must be more than two

degrees from the set point for operation to occur. In heat mode, temperatures must be

below set point and in cool mode temperatures must be above the set point. Temperatures

must be above 33°F for any operation. Operating output conditions are indicated in the

icon at the center of the display.

CW is the closed circulating water loop. When the pump is on, the icon

will animate and show water flow in the system. If the flow switch opens,

or the pump is off, the pipe will appear empty.

This is the compressor symbol. When the compressor is running, the

symbol will look like an operating piston.

SW is the sea water pump. When the pump is on, the symbol will animate and

show the pump operating and water flowing. When the sea water pump is off, the

pipe will appear empty and the pump will not spin.

This is the electric heat symbol. This symbol will appear in heat mode in

place of the compressor if the optional electric heater is installed and

selected in the programmable parameters. The animation will look like

heat rising from the element when the heater is on.
