LCDI power Cord
Automatic 3-minute compressor lockout: After
the compressor cycles off, it will not restart for three
minutes.
Random restart delay: To help eliminate power
surges after a power outage, the unit is equipped with
two to four minute random restart delay feature.
Whenever the unit is plugged in with the master
switch turned on and the mode switch set in the cool
or heat mode, a random restart will occur. A random
restart condition can be avoided by setting the mode
switch in the fan only or off position before applying
power to the unit.
Indication LEDs : The control panel has LEDs that
correspond to fan operation and to indicate unit status.
The LEDs next to the selections ON/OFF, FAN, COOL,
and HEAT indicate which mode is active.

System safety protection
To ensure the system is running safely, the electric
control has the following protections. For problem
solving, please refer to Diagnostic Codes & Solutions
and Troubleshooting sections, pages 13 & 14.
When condenser coil temperature exceeds the presetting point, compressor
decreases the operating frequency to
30Hz. If this protection is inactive and
condenser coil temperature reaches the
shut-down point, the compressor will
be turned off. Thus providing double
protection.

When evaporator coil temperature drops
to 1°C and lasts for 5 minutes, compressor and outdoor fan will stop, indoor fan
keeps on running.
When compressor discharge temperature reaches protection point, compressor will decrease operating frequency
to 30Hz. If this protection is inactive and
discharge temperature reaches the shut
down point, compressor will be turned
off. Thus provide double protections.

When evaporator coil temperature
exceeds the presetting point, compressor decreases the operating frequency

evaporator coil temperature reaches
the shut down point, compressor will
be turned off. Thus provide double protections. This time the back up electric
heater will be turned on.

If compressor starting fails, 3 minutes
later, it will try to start again. It will not
