Smart Touch Cabin Control Installation & Operations Manual

OISTURE
Use Moisture Mode to help control humidity while you are away from the boat or away from a particular cabin. While the control
is in the On Mode, press the Mode icon until the Moisture Mode icon is shown. Once Moisture Mode is enabled, the fan
circulates the air for 30 minutes. During this time, the air temperature is sampled and entered into memory. After 30 minutes, a
cooling cycle starts and continues until the temperature is lowered 2°F (1.1°C) or until the cooling cycle runs a maximum of one
hour.
Four hours after the temperature is satisfied or the cooling cycle times out, this cycle repeats. Moisture Mode will also prevent
your boat or a particular cabin from dropping below a minimum temperature as a means to prevent the contents from freezing.
When the temperature drops low, eliminating moisture may become less of a concern and maintaining some minimum
temperature may become more important. After the 30-minute fan circulation, if the temperature is at or above the factory
default setting of 50°F (10°C), a cooling cycle is started and runs as described above. However, if the temperature is below 50°F
(10°C), a heating cycle will be started instead. The heating cycle will continue until the temperature reaches 50°F (10°C) or until
the heating cycle runs a maximum of one hour. Four hours after the temperature is satisfied or the cooling/heating cycle times
out, the entire cycle repeats, each time determining whether cooling or heating is required. See "General Settings, Humidity
Mode Minimum Temperature" on page 12 for more information on how to adjust the 50°F (10°C) factory default to a different
temperature that may better suit your particular requirements. The adjustment range is 40°F (4.4°C) to 75°F (23.9°C). NOTE for
DX systems only: On systems configured with reverse-cycle heat, the Moisture Mode heat cycle will not be allowed to run when
the ambient temperature is below 40°F (4.4°C). This is necessary to protect the condenser coil from freezing. Systems
configured with electric heat will be allowed to run the Moisture Mode heat cycle regardless of the room temperature.

Automatic Fan Mode
Smart Touch has three automatic fan speeds available: High, Medium and Low. Automatic Fan Mode allows the Smart Touch to
determine the required fan speed based on temperature differential. This permits a balance between the most efficient
temperature control and slower, quieter fan speeds. To select Automatic Fan Mode, press and release the Fan icon until the
word "Auto" above the fan speed graph is shown.
Manual Fan Mode
There are three manual fan speeds available: High, Medium and Low. Manual Fan Mode allows you to select and maintain a
desired fan speed. When a Manual Fan speed has been selected, the speed is indicated by the Fan Speed bar graph. The bar
level will increase as the speed is increased by the user. Press and release the Fan icon until the desired speed is reached.
Fan-Only Mode
Use the Fan-Only Mode to operate the fan for air circulation when no cooling or heating is desired. From the Off Mode press
and release the Fan icon to start Low fan speed. Press and release again to select Medium fan speed. Press and release a third
time to select High fan speed. Press and release a fourth time to turn off the fan or place it in Auto mode. Turning on the control
will revert the fan to the Automatic Mode or the last selected manual fan setting.
NOTICE
For DX systems only: If your air conditioning unit is Cool only (if it does not have a reversing valve) then
Cool Mode MUST be selected. DO NOT set to Automatic Mode for a Cool-Only unit. If Automatic Mode is
selected and the thermostat calls for heat, the compressor will run. Since there is no reversing valve, the
air conditioning unit will supply cool air when heating is desired. Cool-Only units do not heat.

Use the Main Menu settings to adjust operating parameters for your particular needs. Main Menu is also used to fine-tune the
system for the most efficient operation within an installation. (Variables such as ducting, sensor location, and system layout
affect system operation.) The control has factory default settings stored in permanent memory that can be recalled. For this see
Main Menu, Control Parameters, and then Recall Defaults. Reprogrammed new settings can be saved as Memorized settings
and can be recalled and saved at any time. See "Main Menu, Control Parameters, Memorize Settings, and Recall Memorized"
on page 15 for details.
