Condensate Drain Valve; Remote Thermostat Control - LG PTAC Type Product Data Book

Features 6RWU0-03A
Outdoor Air Temperature switchover
This feature changes the operating mode of the unit from the heat pump mode to total resistance heat.
Temperature limits
The unit is programmed to provide both heating and cooling temperature limits by dip switches on the control panel. The
limits are from 50˚ F to 90˚ F. These temperature limits help to prevent overheating and overcooling thereby reducing the
energy costs.

Condensate Drain Valve

The unit has a condensate drain valve to prevent water from collecting and freezing in the basepan.
Quick Heater Recovery
The unit is designed to operate the electric heater so as to warm the room to the desired temperature set point as soon as
the Heat Pump cycle operates. This feature has an advantage of reducing the time to reach the desired temperature for bet-
ter comfort.
Reverse Cycle Defrosting – (PTHP s only)
This feature enables the unit to activate the reverse cycle defrost so as to prevent the formation of ice on the outdoor unit,
which is exposed to cold environment. Formation of ice reduces the airflow through the coil and hence the efficiency of the
air conditioning unit. The LG PTHP employs an active reverse cycle defrost function to melt the ice off the outdoor coil for
ensuring room comfort conditions and savings from extended operation.
High Temperature Heat Pump Operation Protection
When the unit operates at high outdoor temperature conditions during the cooling cycle, this feature switches off the com-
pressor to prevent damage.

Remote Thermostat Control

The PTAC air conditioning unit is designed and built to be operated from any
four(4) or five(5) wire remote mounted thermostat if desired. The unit has a built-
in low voltage power source which can accommodate any of the thermostat
choices – manual, auto changeover or programmable. A remote thermostat can
also be added to any unit.
Zone Sensor
The PTAC air conditioning unit can be controlled by means of a Zone Sensor which carries out the same functions as that of
a Wall Thermostat. In other words, it is a remote wall thermostat.
