Using Thermostat

1. Some electro-mechanical type thermostat has internal delay time to protect compressor.

In that case, mode change can takes time more than user's expectation. Please read thermostat manual carefully if the product does not response quickly.

Setting temperature range by thermostat can be different with that of the product. The heating or cooling set temperature should be chosen within the setting temperature range of the product.

CAUTION

The term "thermostat", which is widely used in this chapter, is a kind of 3rd party accessory. LG Electronics does not supply thermostat. but it can be supplied by 3rd party manufacturers. Room thermostat can be used for easy and convenience control. To utilize thermostat more efficiently and correctly, this chapter presents information about using thermostat.

How to use Thermostat

Operating Thermostat with Remote Controller

To find how to turn on and off, how to set target temperature, how to change operating mode, etc, please refer to thermostat operating manual provided by thermostat manufacturer.

• Following features are permitted when thermostat is installed :

• SET TEMP button

ENGLISH

Using Thermostat

Emergency Operation

• Definition of terms

- Trouble : a problem which can stop system operation, and can be resumed temporally under limited operation without certificated professional's assist.

- Error : problem which can stop system operation, and can be resumed ONLY after certificated professional's check.

- Emergency mode : temporary heating operation while system met Trouble.

• Objective of introducing 'Trouble'

- Not like airconditioning product, hydro kit is generally operated in whole winter season without any system stopping.

- If system found some problem, which is not critical to system operating for yielding heating energy, the system can temporarily continue in emergency mode operation with end user's decision.

• Classified Trouble

- Trouble is classified into two levels according to the seriousness of the problem : Slight Trouble and Heavy trouble

- Slight Trouble : a problem is found inside the indoor unit. In most case, this trouble is concerned with sensor problems. The outdoor unit is operating under emergency mode operation condition which is configured by DIP switch No. 4 of the indoor unit PCB.

- Heavy trouble : a problem is found inside the outdoor unit.

- Option Trouble : a problem is found for option operation such as water tank heating. In this trouble, the troubled option is assumed as if It does not cause in the Product.

• Emergency operation level

- When system met trouble, it stops operation and waits for userʼs decision : Calling service center or starting emergency operation.

- To start emergency operation, user simply pushes ON / OFF button once more.

- Two different levels are prepared for emergency operation : High temperature cycle and low temperature cycle.

- In emergency operation mode, user can not adjust target temperature.

• Following features are NOT permitted in emergency operation :

- Operating mode (cooling/ heating/ weather-dependent) selection

- Time scheduling

- SET TEMP button

• Duplicated trouble : Option trouble with Slight or Heavy trouble

- If option trouble occurs with slight (or heavy) trouble at the same time, the system puts higher priority to slight (or heavy) trouble and operates as if slight (or heavy) trouble is occurred.

- Therefore, sometimes sanitary water heating can be impossible in emergency operation mode. When sanitary water is not warming up while emergency operation, please check if sanitary water sensor and related wiring are all Ok.

• Emergency operation is not automatically restarted after main electricity power is reset.

- In normal condition, the product operating information is restored and automatically restarted after main electricity power is reset.

- But in emergency operation, automatic re-start is prohibited to protect the product.

- Therefore, user must restart the product after power reset when emergency operation has been running.

Operational instructions

n Do not disconnect the power supply of Hydro Kit during the operation.

Stop the Hydro Kit followed by outdoor unit and then only remove the power supply.

If you remove the power supply of the Hydro Kit in the mid of operation, it will leads to damage of the product by freezing and bursting of Plate type Heat Exchanger.

n Do not remove the power supply even at the occurrence of “CH14” Error.

As the error is due to the shortage of water flow, please eliminate any sludge and scales inside the water tubes to ensure free water pumping, remove foreign particles(dust, sand, trash, rusted pieces) from the water tubes along with cleaning the strainer. After cleaning the strainer, to remove the error message (not displayed), turn off the outdoor unit followed by Hydro Kit and then disconnect power supply of Hydro Kit. And then connect power supply and restart the unit for the normal operation.

The service will be charged if the system failure is due to strainer blockage. Strainer cleaning period: Once in every 3 months and whenever CH14 error occurs.

n If the system stopped and displaying any error message(CH ???) please follow below procedure.

Do not remove the power supply of the Hydro Kit. Contact L.G service centre.

n Do not change the water pipes randomly. When changing the water pipes there is a possibility of

foreign material entry and bubble formation as well. This leads to freezing of Plate type heat exchanger of Hydro Kit. When it is essential to change the water pipes, proceed only after separating the pipes from Hydro Kit. The inner side of the new pipes must be washed thoroughly to remove the foreign materials and then connect the pipes with the Hydro Kit.
