button: when operating single unit with cooling only type, it can’t select Heating
mode. When controlling all, if only there is one heat-pump unit, then it can select Heating
mode. But if there are other units with cooling only type among the selected units, then
function confliction will be pointed out, but mode setting operation will not be limited.
b. If the set time is 0, then it means no TIMER operation. When first entering to TIMER
operation, the default time is 0, that is, no timer.

5-7 Communicate with NIM
The CCM and NIM adopt main-auxiliary responsion communication. At any time,
continuously query the running state of one air-conditioner in network 10 times, if not
receiving the feedback data, then it thinks this air-conditioner is power off or doesn’t exist, and
no malfunction warning occurs. If receiving the feedback data, but the communication data is
wrong, then it thinks communication malfunction exists between CCM and NIM, and
malfunction code “
01#
” will be displayed. After normal communication, malfunction will relieve.
Or malfunction code will be eliminated after judging the air-conditioner is power off or doesn’t
exist.
5-8Communicate with Epigyny PC
If receiving data from Epigyny PC, then enter into network control state. If not receiving data
from Epigyny PC for 1 minute, then exit network control state. If data communication has
frame mistake or data check has mistake, CCM/PC communication malfunction will occur and
display malfunction code “
