Installation

Introduction

There will be a hardware and a software part to this installation.

Before physically installing the motor it needs to be paired with the network and with a remote.

Then the motor is installed inside the roller blinds tube.

Pairing with the network

• Put the Zigbee network in pairing mode (see pairing)
• Press the button on the motor 3 times
• The motor will shake

The device exposes the following features:

Remotes

You need to buy one motor with a remote, because the remote is used to set the direction, min and max of the rolling blinds.

There are 3 remotes that I know of. From left to right the ZC175A-9, ZC123a-1 and ZC171A-1.

I've configured my setup using the ZC171A-1 remote (see steps below). The Set button in the back is important.

Installing the motor

The tube is 38mm in diameter.

Pairing

Pairing the remote

• Long-press the motor button, until the motor shakes
• Press the remote Up or Down button immediately after

Unpairing the remote

• Long-press the motor button, until 5 seconds after the motor shakes

Configuration

Reversing the motor direction

• Remote Set 4 times - it should show the number 4
• Press and hold the Up button on the remote until the motor shakes

Setting the upper limit

• Move the roller blinds to the desired position
• Remote Set 1 time, immediately followed by the Up button
• The motor will shake

Setting the lower limit

• Move the roller blinds to the desired position
• Remote Set 1 time, immediately followed by the Down button
• The motor will shake
