Panasonic Aquarea M Series Simple Wired Controller with Wi-Fi Adapter

Description

The Panasonic CZ-RTW2TAW1C is the entry-level control option for the Aquarea M Series T-CAP R290 range — a simple wired room controller with a built-in Wi-Fi adapter, giving the outdoor unit basic standalone functionality without the need for a separate Control Module. It's the right choice where a straightforward single-zone system with app-based monitoring is all that's needed.

Basic functionality — no Control Module required

The M Series outdoor unit can run as a fully standalone system with just this remote controller — no Control Module or additional indoor hydraulic component is required for straightforward single-zone installs.

Need more than basic functionality?

For two-zone control, buffer tank integration, or bivalent boiler backup, you'll need to step up to the Panasonic M Series Control Module (WH-CME5 for single-phase, WH-CME8 for three-phase) — see our matching listings.

Key features

Built-in Wi-Fi adapter

No separate network adaptor accessory needed — Wi-Fi connectivity is built into the controller itself, ready to pair with Panasonic's smartphone apps out of the box.

Aquarea Smart Cloud & Comfort Cloud compatible

Connects to Panasonic's cloud platforms for remote monitoring, scheduling and control from a smartphone or tablet, anywhere with an internet connection.

Aquarea Service Cloud ready

Installers can access the Aquarea Service Cloud for remote diagnostics and maintenance support, reducing the need for site visits to resolve straightforward faults.

Standalone outdoor unit operation

Lets the M Series T-CAP outdoor unit function independently with basic heating and DHW control — no Control Module or hydraulic indoor unit required.

Wired reliability

A hardwired connection to the outdoor unit avoids the reliability concerns of a purely wireless controller, while still offering full smartphone app access via the built-in Wi-Fi adapter.

Wide M Series compatibility

Works across the M Series T-CAP outdoor unit range, from 9 kW residential capacities up to the larger commercial 20/25/30 kW units.

Frequently Asked Questions

Do I need a Control Module as well as this controller?

No — this controller alone lets the M Series outdoor unit function as a standalone system for basic single-zone heating and DHW control. A Control Module is only needed for enhanced functionality such as two-zone control, buffer tank integration or bivalent boiler backup.

Does this include a network adaptor for the app?

Yes — the Wi-Fi adapter is built into the controller, so no separate CZ-TAW1B or similar network adaptor accessory is required to access Aquarea Smart Cloud or the Comfort Cloud app.

Which outdoor units is this compatible with?

The full M Series T-CAP range, including WH-WXG09ME5, WH-WXG12ME5 (single-phase) and WH-WXG09ME8, WH-WXG12ME8, WH-WXG20ME8, WH-WXG25ME8, WH-WXG30ME8 (three-phase).

Can I upgrade to two-zone control later?

Yes — if your requirements change, you can add a Control Module (WH-CME5 or WH-CME8/WH-CME8L depending on phase and capacity) to unlock two-zone control and other advanced functions.

Do I need to be MCS-registered to install this?

The system can be installed by any competent heating engineer, but to claim the UK Boiler Upgrade Scheme grant the install must be carried out by an MCS-certified installer.
