3 General Information
This section provides information on the features, tools,
and high-level screen displays.
This manual provides all the necessary information for
proper installation and operation of the Smart Touch
Cabin Control. Poor installation and misunderstood
operating parameters will result in unsatisfactory
performance and possible failure.

purposes only. Components and component
locations may vary according to specific product
models. Measurements may vary ±0.38 in. (10 mm).
3 .1 How it Works
This section describes the affects of seawater on a
marine climate control system.
The basic principle of an air conditioning unit is the
movement of heat. To cool, heat is removed from the
inside cabin air and transferred to the seawater. To warm,
heat is extracted from the seawater and discharged into
the living space. The efficiency of the system operation
depends on both seawater and cabin temperatures.
• Cool mode operation . The air conditioning unit
operates most efficiently in seawater temperatures
below 90 °F (32 °C). At higher seawater
temperatures, the unit will operate at a reduced
capacity. A high-pressure shutdown may occur at
higher seawater temperatures.
• Heat mode operation . As the seawater gets
colder, less heat is available and the heating efficiency
is reduced. Full heating capacity is obtained at
approximately 55 °F (13 °C) seawater temperature.
Performance drops to about 50% of the rated
capacity in 40 °F (4 °C) water.
In water temperatures below 40 °F (4 °C), the system
pressure can be so low that the unit will shut down
on a low-pressure fault. This problem is compounded
when the cabin is also cold. See “Troubleshooting” on
page 36 for more information.
