2.4 temperature 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
ΔT
afterΔT changes
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 ( e xcept when the
compressor is switched on after being off), the compressor is on and the indicated
maximum frequency should be as follows:
