Introduction
202009 11
The touch-screen centralized controller detects the status of DI2 every 5 seconds. When DI2 is closed,
emergency stop is triggered, and the controller records the operating modes and set temperatures of IDUs that
are active at that moment, and sends a shutdown command to these IDUs. Then, the controller detects the
statuses of DI2 and IDUs every 60 seconds.
If DI2 is still closed, the controller continues to send shutdown commands to IDUs. If DI2 is open, the controller
releases the emergency stop. If "Recovery after emergency stop" is enabled, the controller sends a startup
command to these IDUs and restores the IDUs to the recorded operation statuses before the emergency stop.
After emergency stop is released, the controller will enable "Recover devices after emergency stop" according
to congurations in "Advanced Settings".
Note: Emergency stop can be triggered only on devices that have been started up for more than 3 minutes
3.4 Energy Meter Introduction
To use the “ECS” function of KCCT-384B IPS(A)/(B), an energy meter should be connected to the outdoor
units to monitor the energy consumed which thereby can be sent to the KCCT-384B IPS(A)/(B) and hence it
can be used to bill the tenants of indoor units according to the usage of indoor units done by them.
Two models of energy meter are available from Kaysun, which are listed as follows:
Model Current
DTS 634/636 Up to 60 A
DTS634-F Up to 100 A
The wiring diagrams of the energy meter with the outdoor unit have been discussed in detail in the Part 3
“Functions” of this manual.

4.2 Comparison with K05.2-BACNET(A)
The K05.2-BACNET(A) and KCCT-384B IPS(A)/(B) are the two latest gateway devices available with Kaysun
Amazon series which can be used as a gateway for Kaynet Control PRO software. It is important to analyze
what are the various difference between them. The obvious advantage is that in KCCT-384B IPS(A)/(B) , a
10.1 inch touch screen is present which makes it able to be used independently as well as with Kaynet Control
PRO. The website of KCCT-384B IPS(A)/(B) and K05.2-BACNET(A) are kept here for a comparison. Although
the K05.2-BACNET(A) website has some features similar to KCCT-384B IPS(A)/(B) but the KCCT-384B
IPS(A)/(B) clearly edges ahead of K05.2-BACNET(A) website if we see the full comparison. Below is presented
