NOTE
When powering on the Marine Climate System, press and
immediately release the Power Button in order to not unintentionally
entering Program Mode.
If the Program Mode is entered unintentionally, any subsequent presses
of the Up or Down Button will change the P-1 parameter setting, which
can result in improper system operation.
➤ Press the Power Button (fig. 1 1, page 3) shortly to engage the system.
✓ The display indicates room temperature when the system is on and is blank when
the system is off.
➤ Press the Down Button (fig. 1 3, page 3) or Up Button (fig. 1 5, page 3) to
choose the desired set point.
✓ The display indicates room temperature when the system is on and is blank when
the system is off.
✓ The thermostat is now set to maintain a constant temperature.
➤ Set the desired room temperature by pressing the Up or Down Button.
The set point can be viewed by momentarily pressing and releasing the Up or
Down Button.
The Marine Climate System has nonvolatile memory requiring no batteries or backup
power. When power is lost the operating parameters are retained indefinitely. When
power is restored, the Marine Climate System resumes operating as last pro-
grammed.
Automatic fan speed operation allows fan speed to decrease as room temperature is
approached in the Cool Mode. The fan will operate at low speed when set point is
satisfied.
Manual fan speeds can be selected with the Fan Button.
The fan can be programmed to run only when cooling or heating is required. Nor-
mally the automatic fan speed operation is reversed in the Heating Mode, however,
the fan can be programmed to operate the same as in the Cooling Mode.
