Caution:
Describes precautions that should be observed to prevent damage to the unit.

Warning:

Ask the dealer or an authorised technician to install the unit
- Improper installation by the user may result in electric shock, or fire
Use the specified cables for wiring. Make the connections securely so that any outside forces acting on the cables are not applied to the terminals
- Inadequate connection and fastening may generate heat and cause a fire
Never repair the unit. If the controller must be repaired, consult the dealer
- If the unit is repaired improperly, electric shock, or fire may result
Have all electric work done by a licensed electrician according to “Electric Facility Engineering Standard”, “Interior Wire Regulations” and the instructions given in this manual and always use a special circuit
- If the power source capacity is inadequate or electric work is performed improperly, electric shock and fire may result
Keep the electric parts away from any water – washing water etc…
- Contact may result in electric shock, fire or smoke
To dispose of this product, consult your dealer

Caution:

Safely dispose of the packing materials

Overview

The Smart Grid Adapter is used to connect Air-to-Air products to the Smart Grid. The interface provides 4 modes of operation. Each mode sends commands to the Air-to-Air product to override settings such as drive and temperature set- point.

State	IN1	IN2	Action
1	0	0	Return to previous state
2	0	1	OFF
3	1	0	ON +1°C
4	1	1	ON +2°C

Before the state is changed from state 1 the current operational state of the system is stored and this state is resumed once the inputs return to state 1.

The only exceptions to the above are:

If the user turns the drive off, the unit will go off and remain off even when state returns to 1.
If the user decreases the heating set point this will be allowed but the stored temperature will be set when the override period ends.

If power is lost, the saved state will also be lost and will be read again from the CN105 when power is restored.

The device is powered via the CN105 connector, hence no external power supply is needed.

Compatible model numbers can be found in the appendices of this document.

Caution:

Appendix A lists the compatible indoor units.

Installation

Physical connection
The Smart Grid Adapter has a 1 metre flying lead to connect directly into the CN105 connector on the controller PCB.

Power supply
The Smart Grid Adapter is powered from the CN105 air conditioner host connector at 12V DC and therefore does not require an external power supply.

Inputs
The Smart Grid Adapter has a 3-way terminal to provide 2 volt free inputs. The terminals are Input 1, Ground and Input 2. An input is ‘On’ when shorted to the middle Ground terminal.

Status LEDs

There are two status LEDs on Smart Grid Adapter. The LED indications are as follows:

LED Name	Colour	Functionality
AC ACK	Green	Lit up for one second when device is power up.It will flash to

indicate valid communication with the indoor unit.
MODE| Green| Lit when device is in State 1 otherwise unlit

AC ACK
If this LED do not flashing, check the CN105 connection is secure and the unit type is supported (see appendix).
