Memory
The control’s nonvolatile memory requires no batteries or backup power.
When power is lost, the operating parameters are retained indefinitely. When
power is restored, the control resumes operating as last programmed.
7.3 Modes of Operation
Off Mode
When the Marine Climate System is in the Off Mode, all control outputs are
turned off. Program parameters and user settings are saved in nonvolatile
memory.
On Mode
When the Marine Climate System is in the 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 stored the
last time the unit was operating.
Cool Mode
When Cool Mode is selected, the Cool Mode LED is lit and the cooling
systems are operated as required. When the temperature drops below the
set point, the system will not automatically switch to the Heat Mode.
Heat Mode
When the Heat Mode LED is lit, only the heating systems are selected and
operated as required. Should the temperature rise above the set point, the
system will not automatically switch to the Cool Mode.
Automatic Mode
Automatic Mode provides both heating and cooling as required. The Heat or
Cool LED will be lit according to the mode required.
Temperature in a given mode is maintained within 2 °F (1.1 °C) of set point,
however a 4 °F (2.2 °C) difference is required to allow the Marine Climate
System to change modes.
Once the mode changes temperature will be maintained within 2 °F (1.1 °C)
of set point.
