14. INSTALLATION INFORMATION
14-4. Precautions for Control-related items
14-2-1. Product specification
• To introduce the MELANS system, a consultation with us is required in advance. Especially to introduce the electricity charge
apportioning function or energy-save function, further detailed consultation is required. Consult your local distributor for details.
• Billing calculation for AE-200A/AE-50A/EW-50A/AG-150A-A/EB-50GU-A/TG-2000A, or the billing calculation unit is unique and
based on our original method. (Backup operation is included.) It is not based on the metering method, and do not use it for official
business purposes. It is not the method that the amount of electric power consumption (input) by air conditioner is calculated. Note
that the electric power consumption by air conditioner is apportioned by using the ratio corresponding to the operation status (output)
for each air conditioner (indoor unit) in this method.
• In the apportioned billing function for AE-200A/AE-50A/EW-50A/AG-150A-A and EB-50GU-A, use separate watthour meters for
A-control units, K-control units*1., and packaged air conditioner for City Multi air conditioners. It is recommended to use an individual
watthour meter for the large-capacity indoor unit (with two or more addresses).
• When using the peak cut function on the AE-200A/AE-50A/EW-50A/AG-150A-A or EB-50GU-A, note that the control is performed
once every minute and it takes time to obtain the effect of the control. Take appropriate measures such as lowering the criterion
value. Power consumption may exceed the limits if AE-200A/AE-50A/EW-50A/AG-150A-A or EB-50GU-A malfunctions or stops.
Provide a back-up remedy as necessary.
• The controllers cannot operate while the indoor unit is OFF. (No error)
• Turn ON the power to the indoor unit when operating the controllers.
• When using the interlocked control function on the AE-200A/AE-50A/EW-50A/AG-150A-A/EB-50GU-A/PAC-YG66DCA or
PAC-YG63MCA, do not use it for the control for the fire prevention or security. (This function should never be used in the way that
would put people's lives at risk.) Provide any methods or circuit that allow ON/OFF operation using an external switch in case of
failure.
14-2-3. Installation environment
• The surge protection for the transmission line may be required in areas where lightning strikes frequently occur.
• A receiver for a wireless remote controller may not work properly due to the effect of general lighting. Leave a space of at least 1 m
between the general lighting and receiver.
• When the Auto-elevating panel is used and the operation is made by using a wired remote controller, install the wired remote
controller to the place where all air conditioners controlled (at least the bottom part of them) can be seen from the wired remote
controller. If not, the descending panel may cause damage or injury, and be sure to use a wireless remote controller designed for use
with elevating panel (sold separately).
• Install the wired remote controller (switch box) to the place where the following conditions are met.
- Where installation surface is flat
- Where the remote controller can detect an accurate room temperature
The temperature sensors that detect a room temperature are installed both on the remote controller and indoor unit.
When a room temperature is detected using the sensor on the remote controller, the main remote controller is used to detect a room
temperature. In this case, follow the instructions below.
- Install the controller in a place where it is not subject to the heat source.
(If the remote controller faces direct sunlight or supply air flow direction, the remote controller cannot detect an accurate room tem-
perature.)
- Install the controller in a place where an average room temperature can be detected.
- Install the controller in a place where no other wires are present around the temperature sensor.
(If other wires are present, the remote controller cannot detect an accurate room temperature.)
• To prevent unauthorized access, always use a security device such as a VPN router
AE-200A/AE-50A/EW-50A/AG-150A/EB-50GU-A or TG-2000A to the Internet.
