USING THERMOSTAT

USING THERMOSTAT
The term “thermostat”, which is widely used in this chapter, is a kind of 3rd party accessory. LG Electronics does not supply thermostat and it should be supplied 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. When thermostat is interlocked, the subject of Thermo On / Off is limited to the thermostat
! CAUTION
· 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.
How to use thermostat
To find how to turn on and off, how to set target temperature, how to change operating mode, etc, please refer thermostat operating manual provided by thermostat manufacturer.

ENGLISH

EMERGENCY OPERATION

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, Air-to-Water heat pump is generally operation 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 two levels according to the seriousness of the problem. : Slight trouble and Heavy trouble
– Slight trouble : Sensor trouble. In most case, this trouble is concerned with sensor problems. The unit is operating under emergency mode operation(level 1).
– Heavy trouble : Compressor cycle trouble. Emergency mode operation(level 2) is performed by optional electric heater.
– 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 is not installed at the system.
· Emergency operation level
When the AWHP has any trouble, (1) If there is not a function to judge possibility of operation : Once an error occurs mainly in
indoor unit, AWHP stops. On the other hand, Remocon allows the product to activate On / Off operation.(On : emergency operation) – Slight / Heavy trouble : Heating Operable only – Critical trouble : Full stop – Treatment priority : Critical > Heavy > Slight
(2) If there is a function to judge possibility of operation : Depending on the status of slight / heavy / critical trouble, pop-up phrase is guided separately on display. – Slight trouble : Heating / Cooling Operable – Heavy trouble : Heating Operable only – Critical trouble : Service center request – AWHP operates when user pressed OK button on pop-up window.

ENGLISH

68 EMERGENCY OPERATION
· Duplicated trouble : Option trouble with slight or heavy trouble
– If option trouble is occurred 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.

ENGLISH
