Multiple wall controllers

Nexus wall controllers

Connect up to three (3) Nexus+ wall controllers (CCTSLW+) to a CPU Module (C225) using a CAT5 communication cable.

Nexus with Network Extension Module

The Network Exension Module (CNEM) is an extesion of the iZone Net ports that are available on the CPU Module (C225). This allows for up to ten (10) [Nexus+ wall controllers (CCTSLW+)] to be connected to a single system. Each Network Extension Module requires a 24VAC power supply (CT24ACE) for operation.

Nova DC wall controllers

The following diagram shows how multiple Nova DC wall controllers (CCASLW) can control a single ducted AC system over a shared Wi‑Fi network. The ducted AC unit is connected to a CPU Module (C225) module, which in turn is linked to a Smart Hub (COCBH). The Smart Hub connects to the local network router, acting as the communication bridge between the AC system and all networked controllers. Each Nova DC wall controller connects to the same Wi‑Fi network and automatically discovers the Smart Hub, allowing all controllers to communicate with the single AC system.

In this configuration, multiple wall controllers (up to 6) can operate the same system simultaneously, with commands and status updates synchronised via the Smart Hub.

Nova CAT wall controllers

The following diagram shows a wired Nova CAT wall controllers (CCASLWE) arrangement where each wall controller connects directly to a Screen Link Module (CSL) using a dedicated CAT cable. The Screen Link Module acts as the interface between the wall controller and the CPU Module (C225). Multiple Screen Link Modules are grouped together and connected back to the CPU Module, which links the control system to the ducted AC unit. Each Nova CAT wall controller requires its own Screen Link Module.

The Screen Link Modules are powered via a shared 24VAC power supply (CT24ACE), with a maximum of three (3) Screen Link Modules per power supply. The 24VAC power supply can be connected to any of the Screen Link Modules because the power supplies are all interconnected.

Additional Screen Link Module groups are powered separately as required, allowing the system to scale while maintaining correct power and communication integrity.
