P-2: Moisture Control Mode High Temp Set Point
This function sets the minimum cooling temperature that will be maintained in
Moisture Control Mode. The range for this value is between 95º F and 77º F.
The room temperature where the ECU-Maxx display panel is located (unless a
remote air Temp. Sensor has been installed) will not be allowed to exceed the
temperature selected by this set point. Use the Up and Down buttons to select
the temperature. The factory default value of this setting is 85º F.
P-3: Moisture Control Mode Low Temp Set Point
This function sets the maximum heating temperature that will be maintained in
Moisture Control Mode. The range for this value is between 50º F and 69º F.
The room temperature where the ECU-Maxx display panel is located (unless a
remote air temperature sensor has been installed) will not be allowed to go below
the temperature selected by this set point. Use the Up and Down buttons to select
the temperature. The factory default value of this setting is 55º F.
P-4: Cycle Pump With Compressor
The pump output can be configured in one of two ways:
Off selects continuous operation of the pump when the ECU-Maxx is on.
On selects the function to allow the pump to cycle with the compressor. This
setting reduces pump wear by cycling the pump with the heating or cooling
demand only (factory default setting). In this mode the pump will continue to run
for 2 minutes after the compressor cycles off.
P-5: Temperature Display Units
Program mode ºF selects degrees Fahrenheit (ºF).
Program mode ºC selects degrees Celsius (ºC).
IMPORTANT! All temperature functions will be based on whatever system (F
or C) is selected. ºF is the factory default setting.
P-6: Temperature Calibration
Use this feature to calibrate the air sensor within a range of ±10º.
Enter Program Mode and the current calibration offset will be displayed. Use
the Up and Down keys to set the desired number.
P-7: Cycle Fan With Compressor
Normally, the fan remains on all the time; however, this option allows the fan
to cycle off when the demand for heating or cooling is satisfied.
Off selects continuous operation of the fan (factory default)
On selects cycle fan with compressor. In this mode the fan will shut off 5 to
135 seconds after the compressor, depending on the value for the compressor
start delay.
