Amendment Register

Figure 1: Procon Smart Grid Adapter

The Procon Smart Grid Adapter is a black rectangular device. It features ports labeled 'AC ACK', 'CN105', 'IN1', 'GND', 'IN2', and 'MODE'. Connection point A is identified as "Smart Grid Inputs", and connection point B is identified as the "CN105 connection lead".

1. Safety Precautions

Before installing the unit, read all "Safety precautions". These provide important points regarding safety and must be followed.

Symbols Used in Text:

• Warning: Describes precautions to prevent danger of injury or death to the user.
• Caution: Describes precautions to prevent damage to the unit.

Warnings:

• Ask the dealer or an authorized technician to install the unit. Improper installation may result in electric shock or fire.
• Use the specified cables for wiring. Make connections securely so that external forces on cables are not applied to terminals. Inadequate connection and fastening may generate heat and cause fire.
• Never repair the unit yourself. Consult the dealer for repairs. Improper repairs may result in electric shock or fire.
• All electrical work must be done by a licensed electrician according to relevant standards and manual instructions. Always use a special circuit. Inadequate power source capacity or improper electrical work may result in electric shock and fire.
• Keep electric parts away from water. Contact may result in electric shock, fire, or smoke.
• Consult your dealer for product disposal.

Cautions:

• Dispose of packaging materials safely. Tear apart plastic packaging bags so children cannot play with them, as they pose a suffocation risk.

2. Overview

The Smart Grid Adapter connects Air-to-Air products to the Smart Grid. It offers 4 modes of operation, sending commands to override settings like drive and temperature set-point.

The current operational state is stored when transitioning from State 1 and resumed when inputs return to State 1. Exceptions include:

• If the user turns the drive off, the unit remains off even when returning to State 1.
• Decreasing the heating set point is allowed, but the adapter will override it with the stored set point after the override period ends.

The saved state is lost upon power loss and re-read from CN105 upon power restoration. The device is powered via the CN105 connector; no external power supply is needed. Compatible model numbers are listed in the appendices.

Caution: Appendix A lists compatible indoor units.

3. DIP Switch Settings

The Procon Smart Grid Adapter features an 8-position DIP switch. For normal operation, DIP1 should be set to ON, and all other switches should be OFF.

[Image description: A bank of 8 DIP switches, labeled 1 through 8. Switch 1 is in the 'ON' position, indicated by a red slider. The text "DIP" is visible below the switches.]

5. Installation

5.1. Physical Connection

The Smart Grid Adapter has a 1-meter flying lead for direct connection to the CN105 connector on the controller PCB.

5.2. Power Supply

The Smart Grid Adapter is powered by the CN105 air conditioner host connector at 12V DC, eliminating the need for an external power supply.

5.3. Inputs

The Smart Grid Adapter includes a 3-way terminal block providing 2 volt-free inputs. The terminals are labeled Input 1, Ground, and Input 2. An input is considered 'On' when shorted to the middle Ground terminal.

6. Status LEDs

The Smart Grid Adapter has two status LEDs:

6.1. AC ACK

If the AC ACK LED does not flash, check that the CN105 connection is secure and the unit type is supported (refer to appendix).
