Smart Touch Cabin Control Installation & Operations Manual
MODES OF OPERATION
OFF M
ODE
When the control is in Off Mode, all control outputs are turned off. All settings are saved in nonvolatile memory.
ON M
ODE
When the control is in On Mode, power is supplied to the appropriate outputs and the display indicates the current state of
operation. The operating and program parameters resume based on those last stored when the unit was operating.
A
UTOMATIC
When Automatic Mode is selected, the system provides both heating and cooling as required. The Auto Mode icon is shown.
Cabin temperature in a given mode is maintained within 2°F (1.1°C) of set point by default. (See "General Settings, Set Point
Temperature Differential" on page 13 for instructions on how to reduce this variation to 1°F [0.55°C].) If the system was most
recently cooling, the cabin temperature must drop below the set point by at least 4°F (2.2°C) in order for the system to switch
from cooling to heating. Similarly, if the system was most recently heating, the cabin temperature must exceed the set point by
at least 4°F (2.2°C) in order for the system to switch from heating to cooling. This behavior prevents small temperature
overshoots from causing the system to switch between heating and cooling when it is not necessary.
C
M
OOL
ODE
When Cool Mode is selected, the Cooling mode icon is shown and only the cooling system operates as required. If the ambient
temperature drops below the set point, the system will not automatically switch to the Heat Mode.
H

EAT
ODE
When Heat Mode is selected, the Heating mode icon is shown and only the heating system operates as required. If the ambient
temperature rises above the set point, the system will not automatically switch to the Cool Mode.

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 13 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.
D
EHUMIDIFICATION
The word DEHUMIDIFY displays when the control is in Dehumidification Mode. It flashes if optional humidity sensor is
connected and operating in the Cooling Mode.

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.
