10 INSTALLATION SeTTING ThrOUGh hMI
Outdoor controller board has a HMI (Human Machine Interface) which you can set the status of the outdoor unit.
There are two important settings for installation —— address setting procedure and outdoor control mode setting.
10.1. Address Setting procedure
Before normal running, ITEST is a must process for address setting when the unit is powered on for the first
time. ITEST has to be done only after all installation works are finished.
1. When outdoor is powered on for the first time, “initP” will start blinking on the HMI for about 30 seconds. (Chart 38)
2.And then, HMI will display “in_dd”, which reminds you to go to ITEST for address setting. (Chart 39)
3. Long press MODE button for 5 seconds, then ODU will enter ITEST process and LED1~LED5 will blink “itESt”.
(Chart 40)
4. After about 3-6 minutes, ITEST process will be finished, and HMI will display as “noFbo”. (Chart 41)
5. After that, you can run the VRF system normally.
