• LGE RoHS management ;
A. To preserve, protect and improve the quality of the
environment, protect human health and utilise natural
resources prudently and rationally…
* RoHS : Restriction of Hazardous Substances
Introduction
• Background for EU regulations....
B. Basic principle = preventive action, environmental
damage should be rectified at source and the polluter
should pay
C. If waste cannot be avoided, it should be reused or
recovered for its material or energy.
Declared eliminating the six hazardous substances
specified in the EUʼs RoHS Directive (Pb, Cd, Cr6+, HG,
PBBs, PBDEs) from all LGEʼs products in July 2005.
• LGE ECO-friendly Activity ;
We are operating a special lab for analyzing Hazardous
substance.
- Fully equipped with precision analysis instruments such
as ICP, IC, GC-MS, FR-IR
- Developed and standardized methods to analyze and test
hazardous substance
• LGE Environmental Policy ;
LG Electronics has finalized the development strategy with
the following goals to develop eco-friendly products to
meet a range of environmental challenges and secure
Advanced production technology
3 key Eco-design strategies

- Certified as an official lab by the UL (Underwriters
Laboratories) in February 2005, and by TÜV Rheinland in
May 2006
- Participating in the assessment done by external
organizations
- Enhancing the reliability of internal analysis through
regular assessment of skills, education, workshops and
six sigma activities

• Room thermostat
- Type of thermostat and specification should be complied with chapter 4 and chapter 7 of THERMA V installation
manual.
• 2way control valve
- It is important to install 2way control valve to prevent dew condensation on the floor and radiator while cooling
mode.
- Type of 2way control valve and specification should be complied with chapter 4 and chapter 7 of THERMA V
installation manual.
- 2way valve should be installed at the supply side of the collector.
• By-pass valve
- To secure enough water flow rate, by-pass valve should be installed at the collector.
- By-pass valve should guarantee minimum water flow rate in any case. Minimum water flow rate is described in
water pump characteristics curve.

1.1 Overview
LG Dry Contact is a solution for automatic control of air conditioning system at the ownerʼs behest.
In simple words, itʼs a switch which can be used to turn the unit On/Off after getting the signal from external sources like
key-in lock, door or window switch etc specially used in Hotel rooms.
Itʼs a small PCB that either can be fit inside the control box of Indoor unit or can be outside the unit in a plastic case if there
is no sufficient space inside the Indoor unit.
Apart from simple installation, it can also be linked to Central Controller via Indoor unit PI485 pcb. For this, all connecting
wires & an additional small pcb for looping is also provided along with Dry Contact.
Dry Contact can be used in two ways.
1. It can be used to actually turn On/Off the system on receiving the signal from the source.
In this case, user doesn't need to use remote controller anymore to turn On/Off the system.
However all the further settings like temperature, fan speed, mode etc can be done through remote controller only.
2. Other way is almost similar as above but in this case, after getting the On signal from the external source, user has to
turn On the system from remote controller only. Dry contact just activates the system.
However system can be turned Off directly from the external source. So only On mode is different here.
So in both of above conditions, system canʼt be operated without signal from external source which prevents unnecessary
use of system & facilitates its operation only when its required.
These settings can be selected from the remote controller whose details have been explained in the later part of this manual
So depending upon the requirement, Dry Contact offers a variety of applications to suit the customerʼs requirement in the
best possible way.

1. After deciding where the remote temperature sensor is installed, decide
the location and height of the fixing screws.
(Interval between the screws : 60mm)
Fixing screws

2. Insert the connector of the connection wire into the space for the
connector in place of the room temperature sensor. (CN_ROOM)
3. Separately, set the option code of the attached controller on the indoor unit.
In detail, refer to "installer setting mode" in the owner's manual.
2.2.2 How to connect the remote temperature sensor and the connection wire
The Connection wire does not matter if you change the color of the wire because of non-polar
2.2.3 How to install the remote temperature sensor on the wall

CAUTION
1. Choose the place where the average temperature can be measured for the place the indoor unit operates.
2. Avoid direct sunlight.
3. Choose the place where the cooling/heating devices do not affect the remote sensor.
4. Choose the place where the outlet of the cooling fan do not affect the remote sensor.
5. Choose the place where the remote sensor isnʼt affected when door is open.
