Temperature Hysteresis
Temperature is automatically maintained within the programmed temperature
range of the set point. For example, the factory default value for the temperature
hysteresis is 2º: When the temperature requirement has been satisfied, a 2º shift
is required to establish demand. A 4º shift is required to change from one mode
to the other. Once the required heating or cooling mode has been established, the
hysteresis remains 2º.
Moisture Control Mode
When the ECU-Maxx is configured for Moisture Control Mode, the system
maintains a preset temperature and humidity range. These ranges are program-
mable.

Auto Fan Mode
Automatic fan mode allows the ECU-Maxx to determine the fan speed based on
ambient room temperature. The closer the temperature is to the set point, the
slower the fan speed. This permits a balance between the most efficient
temperature control and slower (quieter) fan speeds.
Manual Fan Mode
Manual fan mode allows the customer to set the fan speed manually.
View Mode
View Mode is one of the Service Modes. View mode allows the user to examine
system voltage, current, inlet water temperature, total compressor run time, HI
and LO Pressure Switch status and the AC line Hz.
Program Mode
Program Mode is one of the Service Modes. Program mode allows the user to
change any of the 34 program settings.
To Turn the Unit On
Press the Power Button once. This toggles the ECU-Maxx from Off Mode to
On Mode. The panel displays will light, indicating that the unit is ready for
operation. If the unit is being turned on after an interruption of power, all lights
on the display panel will turn on for 1 second prior to resuming normal operation.
To Turn the Unit Off
Press the Power Button once to toggle the ECU-Maxx from On Mode to Off
Mode.
Note: The fan will remain on for 4 (four) minutes after the ECU-Maxx is turned
off if heat was being supplied by the Optional CAL Rod Heater.
