DC VOLTS

On certain models of electronic heat pumps, a DC volt

supply is wired to the control board. The operating range

is 10 to 16 volts. If voltage is below 10 volts, you could

experience improper operation of the components within

the heat pump.

NOTE: See Section 4.2B & C for Thermostat Wiring.

8E. SELECTOR SWITCH

The selector switch in a mechanical heat pump has

several positions. The various switch positions can be

tested for continuity with a volt/ohm meter set on the

highest ohm scale.

First turn the 20 amp heat pump breaker to OFF. Next,

remove the wires from the switch. With the switch in

the OFF position, you should not have continuity be-

tween Terminal L1 and any other white numbered ter-

minal.

In the HIGH 2 FAN position, you should have con-

tinuity between Terminal L1 and Terminal 4 only.

In the HIGH 1 FAN position, you should have con-

tinuity between Terminal L1 and Terminal 2 only.

In the LOW FAN position you should have conti-

nuity between Terminal L1 and Terminal 1 only.

In the LOW COOLING position, you should have

continuity between Terminal L1 and Terminal C; and

Terminal L1 and Terminal 1 only.

In the HIGH 1 COOLING position, you should have

continuity between Terminal L1 and Terminal C; and

Terminal L1 and Terminal 2 only.

In the HIGH 2 COOLING position, you should have

continuity between Terminal L1 and Terminal C; and

Terminal L1 and Terminal 4 only.

In the HEAT PUMP position, you should have con-

tinuity between Terminal L1 and Terminal H; and Ter-

minal L1 and Terminal 4 only.

Be sure to check the switch in all positions and be sure you

have continuity only on the terminals for the selected

position. Lack of continuity or continuity on incorrect termi-

nals designates a defective switch, and it must be replaced.

NOTE: The numbers without circles are the white ink-

stamped numbers.

First, turn the 20 amp air conditioner breaker to OFF.

Next, remove the wires from the switch. With the switch

in the OFF position, you should not have continuity be-

tween Terminal L1 and any other white numbered termi-

nal.

In the 1st HIGH FAN position you should have conti-

nuity between Terminal L1 and Terminal 1 only.

In the 2nd HIGH FAN position, you should have con-

tinuity between Terminal L1 and Terminal 2 only.

In the LOW FAN position you should have continuity

between Terminal L1 and terminal 4 only.

In the 1st HIGH COOLING position you should have

continuity between Terminal L1 and Terminal H; and Ter-

minal L1 and Terminal 1 only.

In the 2nd HIGH COOLING position, you should have

continuity between Terminal L1 and H; and Terminal L1

and Terminal 2 only.

In the LOW COOLING position, you should have

continuity between Terminal L1 and Terminal H; and Ter-

minal L1 and Terminal 4 only.

In the 1st HIGH HEATING position, you should have

continuity between Terminal L1 and Terminal C; and Ter-

minal L1 and Terminal 1 only.

In the 2nd HIGH HEATING position, you should have

continuity between Terminal L1 and Terminal C; and Ter-

minal L1 and Terminal 2 only.

In the LOW HEATING position, you should have con-

tinuity between Terminal L1 and Terminal C; and Termi-

nal L1 and Terminal 4 only.
