SYSTEM CONTROL SWITCH - TEST (See Figure 28) Disconnect leads from control switch. Turn control to position being tested. There must be continuity as follows:

1."Off" Position - no continuity between terminals.

2."Lo Cool" Position - between terminals "C" and "3", "C2" and "2", "LO" and "M/S", "AR" and "5".

3."Med Cool" Position - between terminals "C" and "3", "C2" and "2", "M" and "M/S", "AR" and "5".

4."Hi Cool" Position - between terminals "C" and "3", "C2" and "2", "H" and "M/S", "AR" and "5".

5."Hi Heat" Position - between terminals "C" and "1", "C2" and "4", "H" and "M/S", "AR" and "5".

6."Med Heat" Position - between terminals "C" and "1", "C2" and "4", "M" and "M/S", "AR" and "5".

7."Lo Cool" Position - between terminals "C" and "1", "C2" and "4", "LO" and "M/S", "AR" and "5".

8."Fan Only" Position - between terminals "L1" and "M".

FILTER ALERT light will come on after 250 hours of use. Touch FILTER ALERT to reset.

TO SET MODE OF OPERATION

When unit is first turned on, it will be in the COOL mode (light on), with constant fan.

Touch MONEYSAVER (light on) to activate the MoneySaver feature. (MoneySaver is a feature that cycles the fan with the compressor so that the fan does not run all the time. This saves energy and improves dehumidification.) If customer prefers a constant fan for more air movement, touch MONEYSAVER again and unit will return to constant fan.

Touch FAN ONLY (light on) and only the fan will run. This feature may be used in conjunction with the FRESH AIR/ EXHAUST lever to bring outside air into a room, or to exhaust stale air.

TO ADJUST TEMPERATURE

COOLER - Touch COOLER to see setting, touch again to change.

WARMER - Touch WARMER to see setting, touch again to change.

Touch °F/°C to show desired temperature in Fahrenheit or Celsius.

TO ADJUST FAN SPEED

Touch SPEED to see current setting. Touch again to change speed. F1 is lowest setting (sleep setting), F2 is LOW, F3 is MED, and F4 is HIGH.

TO ACTIVATE SMART FAN

Touch SMART FAN (light on). Smart Fan will adjust the fan speed automatically to maintain the desired comfort level. For example, if the outside doors in the home are open for an extended period of time, or more people enter a room, Smart Fan may adjust to a higher fan speed to compensate for the increased heat load. This keeps from having to adjust the fan speed on your own, or from having to change the desired temperature you have selected. Smart Fan will also run to test temperature if the off cycle is long.
