2.4temperature level control 2.4.1 Deviation

Work out the deviation of temperature level as follows:

In heating mode: E=(Remote -control set temperature+ modified value)-room temperature

In cooling & moisture removing mode: E= room temperature -(Remote-control set temperature + modified value)

2.4.2 Compressor OFF

E is minus and E>ΔT

condition forΔT changes

The compressor stops after 120 seconds of continuous detection

When the operation starts,according to the table above, the unit will operate according to the after-the-ΔT-change parameters before the compressor stops for the first time.

From the time the compressor stops to the time it starts again, the operation will follow the ΔT (except the moisture removing mode)

When the operation starts and the operation modes change (except when the idle mode is over) and the deviation is bigger than –ΔT, the compressor starts.

When the compressor is working and the remote -controller set temperature falls below –ΔT, the compressor stops.

2.4.3 Compressor operation

When the compressor is kept idle for 3 minutes, the deviation E will be higher than -△T+0.67℃and the compressor will start working.

2.4.4 DASH operation

When the operation starts or the operation mode changes (except when the compressor is switched on after being off), the compressor is on and the indicated maximum frequency should be as follows:
