The Seeley International MagIQtouch Controller is a smart control unit for managing ducted evaporative cooling and heating systems. Designed for HVAC techs and installers, it offers intuitive operation for both new setups and system upgrades.

Having wrestled with basic thermostats on complex installs, I appreciate a controller that simplifies multi-zone management, especially across varied Australian conditions.

Best For

• Commercial HVAC installers
• Large residential system integrators
• Facilities managers overseeing multiple evaporative coolers or ducted heating systems
• Refrigeration apprentices learning advanced control logic

Compatibility

This controller is built for seamless integration with Seeley International systems, including Braemar ducted gas heating and Climate Wizard cooling units. It's Modbus capable for broader BMS integration. A single MagIQtouch controller can manage up to 60 coolers, provided the total wiring loom length stays under 1,000 metres. Each cooler generally includes a 20m wiring loom, extendable to 40m. If you're running a different model, check fittings and specs before ordering.

Features

• Intuitive touch interface with an in-built installation wizard for quick setup.
• Modbus capability ensures straightforward integration into existing Building Management Systems (BMS).
• Manages up to 60 individual coolers from a single point when paired with an optional Link Module.
• Energy-saving mode automatically optimises pump operation based on external ambient temperature (with optional sensor).
• Allows control of both Braemar ducted gas heating and Climate Wizard cooling from a single unit.
• Offers pin-access for qualified service personnel to fine-tune system settings as needed.

• 1 x MagIQtouch Controller unit

Using It on the Job

1. Mounting: Choose a central, accessible location for the controller, ideally within the conditioned space or a control room if using a remote sensor.
2. Wiring: Connect the supplied wiring loom (typically 20m, extendable to 40m per cooler) to the controller and the associated HVAC unit. Ensure all connections are secure and polarity is correct.
3. Power Up & Initial Setup: Apply power to the system. Utilise the in-built installation wizard to configure initial settings, date, time, and system type (heating, cooling, or both).
4. System Integration: If integrating into a BMS, use the Modbus capabilities. For multi-cooler setups, connect the optional Link Module and additional wiring looms, ensuring total loom length stays under 1,000m.
5. Optimisation: Install optional external air or remote temperature sensors to activate energy-saving modes and fine-tune water and energy usage based on ambient conditions.
6. Verify Operation: Test all controlled units (coolers, heaters) from the MagIQtouch interface, checking for correct setpoint response and mode changes.

Limitations & Safety Notes

• Installation should only be performed by competent service personnel, especially when modifying system settings via pin access.
• Ensure total wiring loom length does not exceed 1,000 metres for multi-cooler installations to maintain reliable communication.
• The advanced energy-saving features require the optional external air sensor to function.
• Always follow manufacturer's instructions and local electrical codes during installation and maintenance.
• This controller is specific to Seeley International systems like Braemar and Climate Wizard; compatibility with other brands is not guaranteed.

When you're commissioning a large install with multiple coolers, run your loom lengths efficiently. Don't just coil up excess cable; cut it to length where possible to keep your Modbus network clean and reliable. It saves you troubleshooting headaches down the line.

Pair With

Pair with an optional Link Module for expanding control to up to 60 coolers, and an external air sensor to unlock the full energy-saving potential of your system. Consider a remote temperature sensor for flexible controller placement.
