* The electric motor will continue to run if it is running when these combinations of thermostat demands occur. The electric
motor will not start to run if these combinations of thermostat demands occur while the electric motor is off and the
condensing unit is in null.
* After the condensing unit has shifted to null and the electric motor has shut off, one of the speed relays (2K or R2K) must
energize to start the electric motor.
