Operation
When the engine start switch is turned ON, the control panel will power the back lighting and turn on all segments of the LCD for 2 seconds. The control panel must be in the ON mode.
Scroll Rate
Temperature selection switches (4) and (5) and fan speed switches (8) and (9) have the ability to scroll. After any of these switches is held for one second, the value will change at a rate of 2 steps per second.
English versus Metric Toggle
In order to toggle between English and Metric readouts, multiple keys must be pressed simultaneously. With the display On, press the temperature selection switch (increase) (4), the temperature selection switch (decrease) (5) and the On/Off switch (1) simultaneously. This will toggle the display between Degrees Celsius and Degrees Fahrenheit.
Functionality of Switches
| On/Off Switch (1) - The control panel will toggle between OFF and ON modes. When the control panel is turned ON, the panel will turn on the back lighting and perform a self-check. The control panel will also display the last recorded settings for air outlet selection, heating and fan speed. The code for ON is also sent to the controller. When the control panel is turned OFF, the LCD display will go blank, the LCD back lighting will remain ON, and the OFF code is sent to the controller. |
| Temperature Selection Switch (Increase) (4) - The temperature selection switch (increase) causes the numeric display on the preset temperature display to increment. This switch also sends the increase code to the controller. A single press of this key is equal to one step. Holding the key down icrements the temperature until released. The size of step is equal to 1°F and .5°C in the automatic mode. The size of step is equal to 1 step in the manual heat mode. |
| Temperature Selection Switch (Decrease) (5) - The temperature selection switch (decrease) causes the numeric display on the preset temperature display to decrement. This switch also sends the decrease code to the controller. A single press of this key is equal to one step. Holding the key down decrements the temperature until released. The size of step is equal to 1°F and .5°C in the automatic mode. The size of step is equal to 1 step in the manual heat mode. |
| Fan Speed Switch (Increase) (9) - While in the automatic fan mode, this switch causes the control panel to send a manual fan code to the main controller. After receiving the setting for the fan speed, the control panel will display the fan speed on the LCD bar graph (7). While in the manual fan mode, this switch causes the control panel to increase the fan speed one step. The control panel also changes the LCD display and sends the new fan speed code to the main controller. Pressing and holding the switch will cause the control panel to function the same, but the fan speed will increase at the scroll rate. The control panel also sends the new fan speed to the main controller after each increment. |
|
| Fan Speed Switch (Decrease) (8) - While in the automatic fan mode, this switch causes the control panel to send a manual fan code to the main controller. After receiving the setting for the fan speed, the control panel will display the fan speed on the LCD bar graph (7). While in the manual fan mode, this switch causes the control panel to decrease the fan speed one step. The control panel also changes the LCD display and sends the new fan speed code to the main controller. Pressing and holding the switch will cause the control panel to function the same, but the fan speed will decrease at the scroll rate. The control panel also sends the new fan speed to the main controller after each decrement. |
| Air Inlet Selection Switch (Recirculate) (11) - When the air inlet selection switch (recirculate) is pressed, the control panel responds by displaying the relative symbol. The panel then sends the code for recirculation to the main control module. |
| Air Inlet Selection Switch (Fresh Air) (10) - When the air inlet selection switch (fresh air) is pressed, the control panel responds by displaying the relative symbol. The panel then sends the code for fresh air to the main control module. |
| Air Outlet Selection Switch (Upper Body) (15) - When the air inlet selection switch (upper body) is pressed, the control panel responds by displaying the relative symbol. The panel then sends the code for upper body to the main control module. |
| Air Outlet Selection Switch (Upper Body and Under Seat) (14) - When the air inlet selection switch (upper body and under seat) is pressed, the control panel responds by displaying the relative symbol. The panel then sends the code for upper body and under seat to the main control module. |
| Air Outlet Selection Switch (Under Seat) (13) - When the air inlet selection switch (under seat) is pressed, the control panel responds by displaying the relative symbol. The panel then sends the code for under seat to the main control module. |
| Air Outlet Selection Switch (Defrost) (12) - When the air inlet selection switch (defrost) is pressed, the control panel responds by displaying the relative symbol. The panel then sends the code for defrost to the main control module. |
| Air Conditioning Override Switch (3) - While in the automatic mode, pressing the air conditioning override switch will cause the control panel to send a code for manual control of the air conditioning system to the main controller. The control module then tells the compressor to remain ON continuously. The air conditioning symbol is then illuminated. |
Note: This application should be used for defogging windows or in a situation where extreme humidity is present.
Note: It is not necessary to push this button in order to utilize the air conditioning system. Cooling can be achieved by simply setting the desired temperature while in the automatic mode.
While in the override mode, pressing the air conditioning override switch will cause the control panel to send a code for automatic control of the air conditioning system to the main controller. The air conditioning symbol is then turned OFF.
| Automatic Temperature Control Switch (2) - While in the automatic temperature mode, pressing the "AUT" switch will cause the control panel to send a code for the blower only mode to the main controller. After receiving the setting for the fan speed, the control panel will display the fan speed on the LCD bar graph (7). The control panel will also send codes to the main controller that turn OFF the a/c clutch and close the water valve. While in the manual temperature mode, pressing the "AUT" switch will cause the control panel to send a code for the automatic mode to the main controller. The LCD display will display "AUT" instead of "the hand". The main controller will then actuate the a/c clutch or the water valve as necessary. The main controller also regulates the fan speed automatically in order to maintain the preset temperature. |
