L-2230 Operation
12-MOISTURE MODE LED The Moisture Mode LED is lit
when the Moisture Mode has been selected. This mode
is used to control humidity during periods when the
vessel is unoccupied.
2.02 Special Button Functions
Service History Log… View the service history log by
pressing the Mode Button immediately after turning on the
AC power, and while all LEDs are illuminated. Exit the
service history log by pressing the Power Button once.
Simultaneously pressing the Power and Down Buttons
while viewing the Service History Log clears the Service
History Log. See the Service History Log section.
Self Test Program… Press the Power Button immediately
after AC power is applied, and while all LEDs are illumi-
nated, to enter the self test program. The self test program
is used to diagnose problems and test the air conditioning
system. For complete details see the Automated Factory
Self Test Program section in this manual.
View Hour Meter… To view the compressor hour meter,
press the Down Button immediately after applying AC
power, and while all LEDs are illuminated. Maximum
recorded time is 65,535 hours. The hour meter functions
are described fully in the Service Tools section of this
manual.
2.03 Dual Button Functions
Up & Down Buttons… Press the Up and Down Button
together and the outside air temperature will be dis-
played, providing the optional outside air temperature
(“OAT”) sensor has been installed. No programming is
required.
Press the Up & Down Buttons simultaneously, while in
the Program mode, to set new custom programming
defaults.
Press the Power & Up Buttons to view the service
sensor temperature. P-8 must be turned on.
2.04 Modes of Operation
Off Mode
When the Elite is in the Off Mode, all control outputs are
turned off. Program parameters and user settings are
saved in nonvolatile memory. The Program Mode can
only be accessed from the Off Mode.
On Mode
When the control is in the On Mode, power will be
supplied to the appropriate control outputs and the
display will indicate 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 the Cool LED is lit, only the cooling systems are
selected and operated as required. When the tempera-
ture drops below the set point, the system will not
automatically switch to the Heat Mode.
IMPORTANT NOTE TO END USER:
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.
Heat Mode
When the Heat LED is on, only the heating systems are
selected and operated as required. Should the tempera-
ture rise above the set point, the system will not auto-
matically switch to the Cool Mode.
Automatic Mode
When the Automatic LED is on, both heating and cooling
is supplied as required. The Heat or Cool LEDs will be lit
when the unit is heating or cooling.
Temperature in a given mode will be maintained within
2°F (1.1°C), however, a 4°F (2.2°C) difference is required
to allow the control to change modes. Once in a new
mode, the temperature will remain within 2°F (1.1°C) of
the set point.
Do not select Automatic Mode if air conditioning unit is
Cool Only (see above).
Moisture Mode
While in the On Mode, press the Mode Button until the
Moisture Mode LED is illuminated. Every four hours, the
fan is started and air circulated for thirty minutes. During
this time the air temperature is sampled and entered into
memory. The cooling cycle is started and continues until
the temperature is lowered 2°F (1.1°C). The compressor
is allowed a maximum of one hour running time to reach
the desired temperature. Four hours after the tempera-
ture is satisfied, or the compressor times out, the cycle
will be repeated.
