You can write setting data to SUHIL HeatPump System by writing settings.
Bit Write
Bit write and word write have the same setting parameters except output value(0 or 1).
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION don't care.
3) ADDRESS don't care. (Fixed to 0)
4) Extra1 Write command of 'Water Heat storage system' = RUN( or R0 ), R1, R2, R3, R6, R7. (Refer to <Table 5>)
Write command of 'Ice Thermal storage system' = RUN( or R0 ), R1, R2, R3. (Refer to <Table 6>)
