This unit has many featrues.The servic er must be

service the unit.
AIR CONDITIONER FEATURES
Compressor Restart Delay
This feature extends the overall life of compre-
ssor by preventing the short-c ycling of the air
conditioner.When the compressor restarts ,the
unit is designed to give a minim um of three
minutes to have a time of equalizing the refrig-
erant pressures for optimizing cycling.
Memory
The unit has memory .If power is lost,all of the
control settings(m ode,fan speed,on/off and
configuration) are remembered.So when power
is res tored,the unit will s tart back up in the mode
(and configuration) it was in,when power was
lost.
Automatic Evaporator Freeze Protection
Automatically to k eep the evaporator from
freezing,the compressor is tuuned off and the
indoor fan is turned on when the evaporator
temperature is too lower.If the evaporator
temperature is not too lower this function is off.
Automatic Defrost Protection (for heat pump
models only)
When the outdoor tube temperature gets too
cold the unit will automatically switch to electric
heating and the compressor will be off. The unit
will then heat with electric heat until the outside
temperature rises enough,so the com pressor
can be used again.
Automatic Quick Warm-up (for heat pump
models only)
If the room temperature falls to 4.5 C/8 F
below the s et point temperature,the reverse
cycle heat is shut off and the electric strip heat
is turned on for one cycle,until heating is
satisfied.
