off defrosting forcibly. The process explained above can only run in heating state, in other words,
the controller will not turn ondefrosting in non-heating mode. After reaching the conditions for
stop defrosting in compressor 1, this compressor 1 will wait compressor 2 to reach those
conditions. As soon as compressor 2 stops, the heating mode will start for both compressors at
the same time (they will have a delay between them).
Remark: when pipe1 sensor faults，pipe2 temperature sensor will be used.
when pipe1 and pipe2 sensor fault ：The system will check external air temperature，if
external air temperature < F35 and the machine run time > Defrost start time，the machine will
defrost；if defrost time > Max defrost time then defrost will stop
6.4.6 WATER PUMP CONTROL
The controller can choose whether to use water pump or not (F40), 0 means no water pump
function, 1 means control the water pump.
When the water pump is running, the compressor starts some time after (F41) and when
the compressor stops, the water pump stops some tima later (F42). When we have the
external alarm or the over probation time alarm, the water pump is switch off immediately.
The compressor won’t start until the water pump achieves the working time of F41. When
the machine stop running, the water pump follow the below loop: F43 stop, F44 run.
6.4.7 CONDICIONES DE FUNCIONAMIENTO VENTILADOR
Cuando F27=-10, el ventilador funcionara en la velocidad normal. En el modelo OPTIMA /
MAYA, el ventilador girara en este régimen fijo.
Cuando F27≠-10，
Si temperatura ambiente ≤F27(20℃), el ventilador funcionara a la máxima velocidad.
Si F27（20℃）＜Temperatura ambiente＜F28（45℃），el ventilador funcionara a la
velocidad normal.
Si la temperatura ambiente ≥F28（45℃), el ventilador funcionara a la máxima velocidad.
Las máquinas OPTIMA / MAYA funcionan en la velocidad normal F27=-10ºC.
