Repeatedly press the Mode button until the Cool Mode indicator LED is on, and cooling will be
supplied when required.
Selecting Heat Only Mode
Repeatedly press the Mode button until the Heat Mode indicator LED is on, and heating will be
supplied when required.
Note: If the water temperature is below the low water limit, the valve and compressor will turn off and
heat will be supplied by the optional CAL rod heater, if installed.

Setting Automatic Mode
Repeatedly pressing the Mode button until the Auto Mode indicator LED is on
places the ECU-Maxx in Automatic Mode, and heating or cooling will be
supplied as needed. In addition to the Auto mode LED, the Cool and Heat LEDs
will be lit when the unit is cooling or heating.
Setting Moisture Control Mode
By repeatedly pressing the Mode button until the Moisture Control indicator
is on places the ECU-Maxx in the Moisture Control Mode. Minimum and
maximum temperatures as well as humidity levels are controlled in this mode.
All parameters are user-programmable.
Adjusting the Set Point
The Set Point should be set to the desired room temperature, as the ECU-Maxx
will maintain temperature to within two degrees of the set point. The maximum
setting for the set point is 85º F. The minimum setting for the set point is 60º F.
To change the Set Point:
Pressing the Up or Down buttons when the ECU-Maxx is in the On Mode
forces the display to show the set point (the Set Point indicator LED will be lit)
and will raise or lower the set point. The speed at which the set point changes
increases with the time the button is held down. The numbers change slowly at
first, then rapidly increase as the button remains depressed. When the up or down
button is released, the display will return to its previous state.
Fan Operation
The Fan Control maintains 6 (six) fan speeds, which are indicated by the Fan
Speed Bar Graph on the control panel. The fan speeds are equally divided with
1 LED lit being Low Fan and 6 LEDs lit being High Fan.
When the ECU-Maxx is placed in Automatic Fan Mode, the fan speeds will
vary according to the difference between room temperature and set point. The
farther room temperature is from the set point, the faster the fan will run. As the
set point is approached, the fan speeds are reduced, culminating in low fan speed
at the set point. A 6º spread between set point and room temperature produces
high fan speed. The fan speed is reduced one number for every 1º reduction in
