SYSTEM CONTROL PANEL ("KQ" Models Only- See Figure 10)

The KQ Model unit uses a five position control switch to regu- late the operation of the unit. Function of each position (clock- wise rotation) is as follows:

Figure 10

System Control Panel (KQ Models Only)

1."Off" - Turns everything off.

2."Hi Fan" - Maximum circulation of filtered room air (no cooling.)

3."Low Fan" - Fan runs slower for less circulation of fil- tered room air.

4."Low Cool" - Fan runs slowly for quiet operation when maximum cooling is not needed.

5."Hi Cool" - Highest fan speed for maximum cooling.

SYSTEM CONTROL SWITCH - TEST (See Figure 11) Turn knob to phase of switch to be tested. There must be continuity as fol- lows:

1."Hi Fan" Position - between terminals "L1" and "H".

2."Low Fan" Position - between terminals "L1" and "L".

3."Low Cool" Position - between terminals "L1" and "L" and "C".

4."Hi Cool" Position - between terminals "L1" and "H" and "C".

EQ Model Only (See Figure 12 )

The EQ Model unit uses a six-position control switch to regulate the operation of the unit. Function of each position (clockwise rotation) is as follows:

1.“Off” Turns everything off.

2.“Fan Only” To circulate filtered room air, but no cooling or heating

3.“Hi Cool” Fan runs continuously, compressor goes on and off to maintain the selected room temperature

4.“Lo Cool” fan runs continuously, compressor goes on and off to maintain the selected room temperature.

5.“Lo Heat” Fan runs continuously, heating turns on and off to maintain the selected room temperature.

6.Hi Heat” Fan runs continuously, heating turns on and off to maintain the selected room temperature.

SYSTEM CONTROL SWITCH – TEST (See Figure 13)

Turn knob to phase of switch to be tested. There must be continuity as follows:

1.“Fan Only” Position – between terminals “MS” and “H”

2.“Hi Cool” Position – between terminals “L1” and “C” and “MS” and “H”

3.“Low Cool” Position – between terminals “L1” and “C” and “MS” and “LO”

4.“Low Heat” Position – between terminals “L2” and “2” and “MS” and “LO”

5.“Hi Heat” Position – between terminals “L2” and “2” and “MS” and “H”
