The second line of the display is the set point. The set point is the
temperature that you are attempting to achieve inside your shelter.
Press the Higher or Lower arrows once and the display will show set point
and the temperature that is currently set.
To change the temperature press once for each degree change or hold the up
or down arrow to scroll and set your new temperature.
When you are finished adjusting the temperature, and no changes are made
for 2 seconds the new temperature setting will lock in and the display will
revert to the normal standard display.
Press and hold the on/off button for 2 seconds. An asterisk will show in the
display to signify that the controller is now ON. While the asterisk is displayed
the controller is actively operating the ECU compressor and/or optional
electric resistance heat.
Any adjustments to temperature setting can be done while the controller is
operating. Simply change the temperature setting by pressing the Higher or
Lower arrow buttons. Once the desired temperature is shown on the
controller it will be accepted as the new setting.
The controller will start to control the shelter temperature by cycling the ECU
thru its heating and cooling modes to maintain the desired setting regardless
of whether it needs to heat or cool. The controller is designed to try and
maintain the temperature within 2 degrees of the set point chosen without
having to switch between heating or cooling modes.
Setting Fan Speed
The ECU is equipped with a two-speed fan. The ECU always starts at LOW
fan speed and can be switched to a high fan speed by the UP/DOWN arrow
