P27: Soft Start Ramp Delay
The compressor soft start feature is a factory-installed option on the ECU-Maxx,
developed to reduce the electrical loading placed on the system when the
compressor starts up. If soft start has been installed on your system, the Soft
Start Ramp Delay Option will adjust the ramp time from 0 to 5 seconds (see
system timing diagram in the System Control algorithm section). The factory
default setting is 2 seconds.
Use the Up and Down buttons to adjust this setting.
P28: Self Test
The diagnostic self test is included to help verify proper operation of the ECU-Maxx. Upon
entering the Test Mode, the following items are checked in the order shown. During the output
checks, "P-28" and "ON" will flash in the display
Select ON to enter Test Mode. The following items are performed in the order
below. During the test, "P-28" and "ON" will flash in the display.
1. EEPROM Memory test: Should this test fail, all dashes: "- - -", will be displayed and
the test will not continue.
2. Air Sensor Test: The face plate air sensor is tested and the temperature displayed.
If the sensor is defective, "AIR" will flash continuously in the display. A good sensor
will display the correct ambient temperature.
3. Lamp Test: All LEDs are turned in for 3 seconds and then turned off.
4. Alternate Air Sensor Test: If installed, the alternate air sensor is tested in the same
manner as the face plate sensor.
5. Water Inlet Sensor Test: The water inlet temperature sensor is checked and should
display the correct water temperature, assuming that it has been properly installed. A failed
water sensor test will continuously flash "H2O" in the display.
6. Fan Test: The fan is started and brought up to speed. Each fan speed is tested for
5 seconds.
7. Valve Test: The valve is cycled on for 5 seconds and then turned off.
8. Pump Output Test: The pump is turned on for 5 seconds and then turned off.
9. Compressor Test: The compressor output is turned on for 10 seconds and then
turned off.
10. Firmware Version will be displayed and then the display will blank out.
Self test can be cancelled at any time by pressing the Power Button. When the
Self test is completed ECU-Maxx will exit to the OFF mode.
P29: Outside Air Option
When this option is turned ON, the Alternate Air input jack is used as an
outside air sensor input.
