Commissioning Field Controllers
To commission the VMA1617 or VMA1632 controller,
use the following procedure:
1. Download the control application to the
controller using the Controller Configuration
Tool (CCT). Refer to the
Controller Tool Help
(LIT-12011147)
and
Controller Provisioning with
Tools (LIT-12013247)
.
2. Commission the VAV Box.
3. Perform airflow balancing on the VAV box.
Refer to the
VAV Balancing Tool Technical Bulletin
(LIT-12011087)
.
4. Perform commissioning checkout procedures.
Refer to the
Controller Tool Help (LIT-12011147)
and
Controller Provisioning with Tools
(LIT-12013247)
.
You commission controllers with the CCT software.
The controller can be connected in one of four
ways; either through NxE Passthru, MAP 4.2+/
BACnet Router (Mobile Access Portal (MAP)
Gateway at version 4.2 or above), through Bluetooth
(using BTCVT), or Direct Ethernet connection to
the controller. Refer to the
Controller Tool Help
(LIT-12011147)
and
Controller Provisioning with
Tools (LIT-12013247)
for detailed information about
commissioning field controllers.
Note:
• The MAP Gateway serves as a replacement
for the BTCVT, which is no longer available
for purchase, but continues to be supported.
Repair information
If the controller fails to operate within its specifications, replace the unit. For a replacement unit, contact the
nearest Johnson Controls representative.
Troubleshooting
Table 10 provides LED status indicator information
for troubleshooting the controllers.
Note:
If you experience short circuits in the 24
VAC power supply causing protective devices
such as breakers or fuses to trip, make sure
that the power connections on the VMA are
not reversed. The most common cause of this
problem is when the 24 VAC power supply
on the VMA is reversed but not reversed on a
connected secondary device. Improper wiring
of this power terminal may cause a short circuit
across the 24 VAC power supply on -1 models.
