Multiple Q Series Coolers Installation Using MagIQtouch Wall Controller
Applies to: MagIQtouch Controller
Product Category: Evaporative Cooling Systems
Last Updated: July 2025
Important Note!!! MagIQcool and MagIQSwitch Plate Controllers are not compatible with multiple cooler installations.
Summary
To ensure reliable and stable operation of your MagIQtouch touchscreen controller in a multiple cooler setup, it is essential to follow the manufacturer’s cabling recommendations. Incorrect cable types, excessive lengths, or the use of joiners and hubs in unsupported configurations can cause voltage drops, leading to intermittent dropouts and degraded performance.
Recommended Setup
- Use the 20-metre communication cable supplied by the manufacturer to connect the wall controller to the first cooler.
- Joiners are not recommended by the manufacturer under any circumstances.
- Hubs are not recommended by the manufacturer between the wall controller and the first cooler in multiple cooler installations.
- You may use longer cables beyond the initial 20m segment after the first cooler, with a total system cable length not exceeding 500 metres.
- The system supports up to 60 coolers connected in a daisy-chain configuration.
Why This Matters
The MagIQtouch controller uses capacitive touchscreen technology, which is sensitive to voltage fluctuations. Unsupported cabling configurations can introduce resistance and signal degradation, resulting in:
- Reduced touchscreen responsiveness
- Random disconnections
- System instability
