3. System requirements

Image

The PIERRE Wave (Zigbee 3.0, 2.4 GHz) system consists of the following components.

Required

  1. PIERRE Wave products: switches, modules, sensors, thermostats and other devices. They connect wirelessly to the gateway.
  2. Gateway: a PIERRE display and/or gateway. It links all PIERRE Wave devices and handles the communication with the app.

Optional

  1. Smart PIERRE app: control and monitoring from a smartphone or tablet. Not required for basic operation.
  2. Router: gives the gateway internet access for remote control.

Operation: the gateway connects to the router by Wi-Fi or LAN. PIERRE Wave products communicate wirelessly with the gateway in both directions: commands are sent and status updates are received through the Smart PIERRE app.

What you need

A PIERRE Wave (Zigbee 3.0, 2.4 GHz) gateway: a PIERRE display and/or gateway.

Image

Warnings:

  • Installation must be carried out by a qualified electrician in accordance with local regulations.
  • Keep the device out of reach of children.
  • Keep the device away from water, damp or hot environments.
  • Install the device away from strong signal sources such as microwave ovens that may cause signal interruption resulting in abnormal operation of the device.
  • Obstruction by concrete wall or metallic materials may reduce the effective operation range of the device and should be avoided.

5. Manual Override

The switch module terminal reserves the access of manual override function for the end-user to switch on/off.

  • Switch on/off for permanent on/off function.

Notes:

  1. Both the adjustment on App and switch can overwrite each other, the last adjustment remains in memory.
  2. The App control is synchronized with the manual switch.

  2. Connect wires according to the wiring diagram.

Run Wires Cross-section Cable type Conductors
From electric box to light module 2 1.5 mm² NYM-O L, N
From light module to light fittings 5 1.5 mm² NYM-J L1, L2, L3, L4, N
From light module to switches 5 0.75 mm² NYM-J COM, S1, S2, S3, S4

Three runs. The supply into the module is two conductors at 1.5 mm², line and neutral. Out to the fittings: 4 switched lines (L1–L4) plus the neutral at 1.5 mm², one switched line per fitting. The wall switches are looped on 0.75 mm²: common and S1–S4, one input per gang. Because the neutral is present at the module, this variant also works as a Zigbee repeater.

8. FAQ

Q1: What should I do if I cannot configure the light module?

  • Check that the module is powered.
  • Make sure the PIERRE Wave gateway (PIERRE display and/or gateway) is online.
  • Check the wiring against the diagram.

Q2: What loads can be connected to this module?

Lighting loads such as ceiling lamps and panel lights, within the rated load given in the specifications.

Q3: What happens if the Wi-Fi or internet goes down?

The module keeps working locally. You can still switch the light with the wall switch and control it from the PIERRE display and/or gateway; only remote access from the app is unavailable.

Q4: How do I reset the module?

Either toggle the connected wall switch 5 times, or press and hold the reset key for about 10 seconds, until the indicator light flashes.

Q5: What happens during a power cut?

The module keeps its last state and comes back when power is restored.

Q6: What size wall box does the module need?

See the Product Size section. The module fits behind the switch in a standard wall box; a deep box makes wiring easier.

Q7: What is the difference between the neutral and no-neutral modules?

Modules with a neutral also act as Zigbee repeaters and strengthen the network. Use the no-neutral module where no neutral is available at the switch.

Q8: Can any switch or button be used?

Yes. Any standard wall switch or push-button can be connected to the S inputs.

Q9: Does it support multi-way switching?

Yes. See the diagrams in the Wiring Instructions and Diagrams section.
