Checking Procedures - Johnson Controls CIS01 Installation & Maintenance Manual

NOTICE
A. Use AWG 22 (0.32mm
If the total cable length is longer than 98.4 ft. (30m), use communication cable of 1P to AWG 18 (0.82mm
Maximum total cable length 1640.5 ft. (500m). When using with the control timer, the maximum total cable length
is 328.1 ft. (100m).
Using other cables may cause a malfunction because of Electromagnetic Interference (EMI).
B. Maintain a distance of more than 12 inches (30cm) between the controller / indoor unit communication cables and
the power cables.
C. If installed within 12 inches (30cm), put the cables in a conduit tube and ground (type-D; ≤100Ω), one end of the
pipe. Without this procedure, malfunction or failure of the air conditioner because of EMI may occur.
D. When multiple indoor units are simultaneously controlled, set addresses for the refrigerant cycle and indoor units.
Specifi cally, when the indoor units from multiple refrigerant cycles are simultaneously controlled, a communication
issue may develop due to address duplication.
E. For more information about wiring controller-indoor units and setting indoor unit addresses, refer to "Unit No.
Setting" of each Installation and Maintenance Manual of indoor unit for details.
F. Do not leave any space at the cable opening of the remote controller case. If there is any space, cover it with,
for example, tape to avoid trouble caused by condensation or insects entering the controller case.

5. Checking Procedures

This controller is not equipped with the Test Run mode.
The test running must be performed from the outdoor units.
1. Turn ON the power for all indoor units.
2. Models with automatic addressing will take 3 to 5 minutes to complete the setting.
3. Set the Test Run mode from the outdoor units.
4. Cancellation the Test Run mode.
The Test Run mode can be canceled when:
- Test Run fi nishes automatically after 2 hours running time.
- Cancel Test Run from the outdoor units.
- Stop Test Run by pressing the On/Off switch at the controller.
The total number of the indoor units connected is
indicated on the temperature display.
If the indicated number of connected units is incorrect, any communication abnormality because of an incorrect wiring/
addressing or EMI issue may exist. In such a case, turn OFF the power supply and check the following.
(Do NOT repeat the ON/OFF operation at the main switch within 10 seconds).
(1) Indoor unit(s) power supply not turned ON, or incorrect wiring
(2) Incorrect wiring connection between indoor units or controllers
(3) Incorrect setting of rotary switch (overlapped setting)
