Gas Pressure Measurement In Inverter Products Table
To measure the gas pressure values and compare them to the gas pressure table in cooling in inverter air conditioners manufactured
in 2020, the steps below should be followed, and a performance test application that will fix the compressor frequency of the
product at 55 Hz should be started.
1.
Set the indoor unit fan cycle to high speed via remote control.
2.
Set the setting temperature to 18°C via remote control.
3.
When the product is turned on, press repeatedly on the sleep mode on the remote control for 6 times after applying the
operations in items 1 and 2. (At the end of each pressing, buzzer voice should be heard from the indoor unit; the 6th buzzer
voice should last longer.)
4.
With the operation in item 3, performance control application of
5.
the product working in cooling mode will start, the compressor frequency will be fixed at 55 Hz and the indoor unit fan motor’s
cycle will reach the highest cycle in the fan profile of the product.
6.
,In order to disable the performance test algorithm, the air conditioner should be turned off and on again with the remote control.
(Unless this operation is carried out, the product will continue to stay in performance test mode.
To measure the gas pressure values and compare them to the gas pressure table in heating, the steps below should be followed,
and a performance test application that will fix the compressor frequency of the product at 55 Hz should be started.
1.
Set the indoor unit fan cycle to high speed via remote control.
2.
Set the setting temperature to 30°C via remote control.
3.
When the product is turned on, press repeatedly on the sleep mode on the remote control for 6 times after applying the
operations in items 1 and 2. (At the end of each pressing, buzzer voice should be heard from the indoor unit; the 6th buzzer
voice should last longer.)
4.
With the operation in item 3, performance control application of the product working in cooling mode will start, the compressor
frequency will be fixed at 60 Hz and the indoor unit fan motor’s cycle will reach the highest cycle in the fan profile of the
product.
5.
In order to disable the performance test algorithm, the air conditioner should be turned off and on again with the remote control.
(Unless this operation is carried out, the product will continue to stay in performance test mode.)
