Dry Contact (PQDSA) 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.

Remote Temperature Sensor (PQRSTA0) 2.2 Installation Method 2.2.1 How to use 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 60mm 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 Integrate the remote temperature sensor with the screws as the order of arrows. Accessories Fixing the Remote Sensor 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. 6 _ Air-to-Water Heat Pump 3. PI485 (PMNFP14A0) 3.1 Part Description L1 2 3 4 ON KSDO4H 1 2 3 4 5 6 7 8 9 10 11 !
