Safety Precautions

Read these Safety Precautions carefully to ensure correct installation.
This manual classifies precautions into WARNING and CAUTION.
WARNING :
Failure to follow WARNING is very likely to result in such grave
consequences as death or serious injury.
CAUTION :
Failure to follow CAUTION may result in serious injury or
property damage, and in certain circumstances, may result in
a grave consequence.
Be sure to follow all the precautions below ; they are all important for
ensuring safety.
 Installation should be left to the dealer or another qualified professional.
Improper installation by yourself may cause malfunction, electrical shock, or fire.
 Install the set according to the instructions given in this manual.
Incomplete or improper installation may cause malfunction, electrical shock, or fire.
 Be sure to use the standard attachments or the genuine parts.
Use of other parts may cause malfunction, electrical shock, or fire.
 Disconnect power to the connected equipment before starting installation.
Failure to do so may cause malfunction, electrical shock, or fire.
 An earth leakage circuit breaker should be installed.
If the breaker is not installed, electrical shock may occur.
 Do not install the set in a location where there is danger of exposure to
inflammable gas.
Gas accumulated around the unit at the worst may cause fire.
 To prevent damage due to electrostatic discharge, touch your hand to a
nearby metal object (doorknob, aluminum sash, etc.) to discharge static
electricity from your body before touching this kit.
Static electricity can damage this kit.
 Lay this cable separately from other power cables to avoid external
electrical noises.
After installation is complete, test the operation of the PCB set to check
for problems, and explain how to use the set to the end-user.

1.Overview, Features and Compatible Models
This kit is the interface required when connecting the central controller and a Daikin Room Air
Conditioner. Use of the central controller makes it possible to perform the following monitoring
and operations. It is compatible with room air conditioners which have an HA connector S21.
1.Run / stop for the central controller and wired remote controller, operating mode
selection, and temperature can be set.
2.The operating status, any errors, and the content of those errors can be monitored
from the central controller and wired remote controller.
3.Run / stop for the central controller and wireless remote controller, operating mode
selection, and the temperature setting can be limited by the central controller.
4.Zone control can be performed from the central controller.
5.The unit can remember the operating status of the air conditioner before a power
outage and then start operating in the same status when the power comes back
on.
6.Card keys, operating control panels, and other constant / instantaneous
connection-compatible equipment can be connected.
7.The Operating / error signals can be read.
8.HA JEM-A-compatible equipment can be connected.
9.The indoor temperature can be monitored from the Ve-up controller.
Precaution
1.When reading the Operating / error signals, a separate external power source
(DC 12V) is needed.
2.A separate timer power source (DC 16V) is needed when using the schedule
timer independently, and not in conjunction with other central controllers.
3.The range of temperatures that can be set from the central controller is 18°C to
32°C in cooling and 14°C to 28°C in heating.
4.Fan operation cannot be selected from the central controller or wired remote controller.
5.Group control (i.e., control of multiple indoor units with a single remote controller) is
not available.
6.Monitoring is not available of the thermo status, compressor operating status,
indoor fan operating status, electric heater, or humidifier operating status.
7.Forced thermo off, filter sign display and reset, fan direction and speed settings,
air conditioning fee management, energy savings instructions, low-noise
instructions, and demand instructions cannot be made.
