The instructions below must be followed to prevent product malfunction, property damage, injury or death to the user or other people. Incor-
rect operation due to ignoring any instructions will cause harm or damage. The level of seriousness is classified by the symbols below.
SAFETYINSTRUCTIONS
WARNING
The information in this manual is intended for use by a
trained technician familiar with the U.S. National Electric
Code (NEC) who is equipped with the proper tools and test
instruments.
Failure to carefully read and follow all instructions in this manual may
result in equipment malfunction, property damage, personal injury and/
or death.
Risk of electric shock. Disconnect all power before
servicing.
Do not install the MultiSITE Controller unit if it will be
exposed to rain or other precipitation.
Do not install the unit in a location exposed to open ame
or extreme heat.
Do not touch the unit with wet hands.
There is risk of re, electric shock, physical injury and/or death.
Replace all control box and panel covers.
If cover panels are not installed securely, dust, water and animals may
enter the unit, causing re, electric shock, and physical injury or death.
Wear protective gloves when handling equipment.
Sharp edges may cause personal injury.
Dispose of any packing materials safely.
• Packing materials, such as nails and other metal or wooden parts
may cause puncture wounds or other injuries.
• Tear apart and throw away plastic packaging bags so that children
may not play with them and risk suffocation and death.
Do not change the settings of the protection devices.
If the pressure switch, thermal switch, or other protection device is
shorted and forced to operate improperly, or parts other than those
specied by LG are used, there is risk of re, electric shock, explosion,
and physical injury or death.
If the air conditioner is installed in a small space, take mea-
sures to prevent the refrigerant concentration from exceed-
ing safety limits in the event of a refrigerant leak.
Consult the latest edition of ASHRAE (American Society of Heating,
Refrigerating, and Air Conditioning Engineers) Standard 15. If the re-
frigerant leaks and safety limits are exceeded, it could result in personal
injuries or death from oxygen depletion.

SAFETY INSTRUCTIONS
MultiSITE Controller is for use with select LG commercial air
conditioning systems only.
Do not attempt to use MultiSITE Controller with any other
type of system. Refer to the compatible equipment list in this
manual.
There is risk of equipment damage or degraded performance
Do not cut, lengthen or shorten the cable between the
MultiSITE Controller unit and the indoor unit.
Do not install the MultiSITE Controller unit in a location
where the cable cannot be safely and easily connected be-
tween the two units.
Do not allow strain on this cable.
There is risk of equipment damage.
Clean up the site after all procedures are nished, and check
that no metal scraps, screws, or bits of wiring have been left
inside or surrounding the controller or indoor units.
Provide power to the outdoor unit compressor crankcase
heaters at least six (6) hours before operation begins.
Starting operation with a cold compressor sump(s) may result in severe
bearing damage to the compressor(s). Keep the power switch on during
the operational season.
Do not block the indoor unit inlet or outlet.

INTRODUCTION
MultiSITE CRC1 Series Controllers
This manual describes how to use the LG MultiSITE Commercial
Remote Controllers (CRC) 1. There are two models of this controller:
• MultiSITE CRC1 (Model PREMTBVC0)
• MultiSITE CRC1+ (Model PREMTBVC1)
The two models are identical with the exception of two functions
included in the MultiSITE CRC1+ only:
• Motion sensor
• Humidity sensor
Compatible Equipment
MultiSITE CRC1 Controllers are compatible with LG Commercial
Air Conditioning indoor units (except PTAC units).
Do not attempt to use a MultiSITE CRC1 controller with any
other equipment.
Accessories
These accessories are available for MultiSITE CRC1 controllers:
• ZigBee®Pro wireless card Model ZVRCZPWC1
• Door and window switch Model ZVRCZDWS1
• Wall mounted occupancy sensor Model ZVRCZWOC1
• Ceiling mounted occupancy sensor Model ZVRCZCOC1
The ZigBee®Pro wireless card is required for communication
between the controller and the other accessories.
Safety
Safety of personnel is the primary concern during all procedures.
Read and understand the safety summary at the front of this manual.
Ensure the controller is installed in accordance with the appropriate
LG installation manual.
WARNING
If troubleshooting is required, it must be performed by trained personnel
and in accordance with national wiring standards and all local or other
applicable codes. Improper troubleshooting and repair/replacement of
equipment can result in re, electric shock, physical injury, or death.
Note:
Improper troubleshooting and repair/replacement of equipment can
result in damaged equipment or degraded operation.

CONTROLLER OVERVIEW
Adjusting Setpoints in Auto Mode
Setpoints can be modied in three di󰀨erent ways when in Auto Mode: Cooling Setpoint change, Heating Setpoint change, or
Cooling/Heating Setpoint change.
Auto Mode, Cooling Cycle, Cooling Setpoint (Dual Setpoint setting)
When in cooling cycle of Auto Mode, use the up and down arrows to raise or lower the cooling setpoint.
When the setpoint is modified it will increase or decrease the difference between the cooling and heat-
ing setpoint values. The minimum difference allowed between cooling and heating setpoints is determined
by the Deadband control value setting (found in the Setpoint Config screen). "Cooling Setpoint" shows as
indicated on the screen to the left.
Auto Mode, Cooling Cycle, Heating Setpoint (Dual Setpoint setting)
To change the heating setpoint when in Auto Mode, cooling cycle, tap the up or down arrows to place the
controller into set point configuration mode and then immediately tap the Mode button once to change to
heating set point mode. "Heating Setpoint" shows when this parameter is set. Immediately move back to the
set point up or down arrows to change the heating set point.
Auto Mode, Cooling Cycle, Cooling/Heating Setpoint (Dual Setpoint setting)
To change the cooling and heating setpoints simultaneously, a third option is available for adjusting set-
points. If in Auto Mode (either cooling or heating cycle), tap either the up or down set point buttons, then
immediately tap the Mode button until “Cool/Heat” shows, indicating that the controller is in the correct set
point mode. Immediately move back to the up or down set point buttons to change the set points as desired.

sequence of operation
In Cooling mode, the setpoint displayed in the bar is the cur-
rent occupied cooling setpoint.
During occupied setpoint adjustment, the large digits are tem-
porarily used to display the occupied cooling setpoint while it
is adjusted.
Normal temperature display resumes after the setpoint is
adjusted and the actual occupied cooling setpoint is displayed
in the setpoint bar.
Heating mode or heating only
sequence of operation
In Heating mode, the setpoint displayed in the bar is the cur-
rent occupied heating setpoint.
During occupied setpoint adjustment, the large digits are tem-
porarily used to display the occupied heating setpoint.
Normal temperature display resumes after the setpoint is
adjusted and the actual occupied heating setpoint is displayed
in the setpoint bar.
Automatic Heating / Cooling mode
In automatic mode, the setpoint displayed at the top of
the set point bar represents the actual occupied cooling
setpoint.
During occupied setpoints adjustment, the large digits are
temporarily used to display the occupied “Cooling Set-
point” or occupied “Heating Setpoint”. The actual setpoint
is dependent on the last effective demand (heating or
cooling).
Normal temperature display resumes after the setpoints
are adjusted and the actual occupied heating and cooling
setpoints are displayed in the setpoint bar.
