6.4 Parameter List
6.3 Output Action
●
When the indoor temperature T1 >
K,L
, or T1 <
LOL
, relay OUT2 will be ‘ON’ start
the air conditioner to cool or heat.
●
When the indoor temperature T1 >
AL1
and temperature difference(T1-T2) >
DT
,
relay OUT1 will be ‘ON’ start the aeration fan to cool.
In order to avoid compressor switch off and on frequently, must set the minimum off
time

,
RT2
between the switch OFF and switch ON, regardless of the input value.
