Ова е од Даикин сервисер. На англиски е. Објаснува за дефростите.
Значи вели користи логика до -28 после тоа оди на тајмер дефрост секои 24 минути.
Ако дефростот е неуспешен прај нов после 24 мин се додека термисторот на саќето не ја измери потребната температура но не подолго од 12мин...
Она што јас го постирав претходно.
Ако некој сака нешто да научи нека го преведе во Google Translate
"All units in the XRH range (RXTA/RXTM/RXTP) have good logic for defrost in/out, but only down to -28C approx. Below this temperature we are not extrapolating the defrost start temperature and it operates by guard setting (every 24 minutes) On the 40 class however, we have identified that if the unit operates for longer periods in low/moderate compressor frequency we can have a liquid build up in the indoor unit and that can result in a premature defrost due to incorrect refrigerant flow in the circuit. For this case we have a service software that changes the control logic of the expansion valve in a limited operating range. In mass production this has been fixed since some years ago.
The main reason for this behavior of double defrost is the logic of the unit. If a defrost is detected to be NG then the unit does a new defrost after 24 minutes. The defrost is stopped either by temperature reached on outdoor he (OK defrost) or by security timer (max 12 minutes defrost) and the temperature is not reached (not OK defrost, new defrost request ASAP = after 24 minutes) In most cases the temperature is not reached by wind component."
