the compressor stops.
For example:
If set temperature is 18
℃,
【
U22
】
is 2
. When the temperature
20
, compressor starts. If
℃
≧
℃
the temperature
16
≦
℃,
compressor stops. The room temperature will be between 18±2
.
℃
● Compressor emergent on
Press and hold “▼” key for 5 seconds, the compressor will power on if the following meets:
◆
The compressor has stopped for "U10";
◆
The controller is not in defrosting or dripping water states;
◆
Room
temperature
is
between
"Set
temperature"+”U22”
and
“Set
temperature”-”U22”.
After compressor emergent on, when room temperature goes down to “Set
temperature”-”U22”, it stops cooling.
7.2 Compressor Delay Protection
● After power supply, the compressor is able to start only after the time (U10) has passed.
● After the compressor stops, it is able to restart again only after the time (U10) has passed.
● After the compressor starts, it is able to stop only after the time (U11) has passed.
7.3 Fan Control (Only for ZL-630A-R)
7.3.1 Fan control mode: Controlled mode and free mode.
7.3.2 Controlled mode
●
In the state of cooling, when the evaporator temperature is less than (U40), or the cooling
time is more than (U41), the fan will starts.
●
If set 0 for (U41), the fan will start immediately when come into the cooling state.
●
After cooling stops, the fan will stop after the time of (U41).
●
If set 0 for (U41), the fan will stop immediately when cooling stops.
7.3.3 Free mode
The fan will be always running, except during defrosting. In this mode, (U40), (U41) and
(U42) parameters have no effect.
7.4 Protection Running Mode When Room Temperature Sensor Fails
When the room temperature sensor fails, the system will automatically run into the protected
running mode. In this mode, the compressor will run and stop with the period of 30 minutes.
Compressor works for U12* 3 minutes, stops for
﹛
30 - (U12* 3)
﹜
minutes.
For example: Set
【
U12
】
is 3
,
when the temperature sensor fails
,
compressor runs for 9
minutes and then stops 21 minutes, move in circles. If U12=0, system stops when sensor fails
7.5 Protection Running Mode When Defrost Temperature Sensor Fails
(for ZL-620A-R, ZL-630A-R)
● When the defrost sensor fails, the controller will periodically defrost according to (U30)
and (U31). The dripping water function will be cancelled.
● If the fan is in the "controlled mode", it will cancel the conditions of fan temperature
control; the fan will work according to (U41) and (U42) parameter. (For ZL-630A-R)
7.6 Defrosting Function
7.6.1 Automatic defrosting
●
When the compressor continuously running time reaches the time of defrost cycle (U30),
the system starts to defrost.
●
When one of the conditions (defrosting end time (U31) and defrosting end temperature
