How it works
The brain behind your cooling.
Every fan coil unit ships with our load-compensated controller built in. It detects when your heat pump is producing chilled water and activates automatically — no manual switching, no complicated setup.
Included in every fan coil unit — not a separate purchase.

Key features
Set it and forget it
Automatic activation
The controller monitors the water temperature coming from your heat pump. The moment it detects chilled water, cooling activates automatically. When the heat pump switches back to heating, cooling stops. No manual switching between seasons.
Fan modulation
Set your target room temperature on the controller. The fan speed modulates continuously to match — running faster when the room is warm, slowing down as it approaches your target. Quieter operation, less energy, more comfort.
Load compensation
On a 35°C day, your heat pump works hard to chill water to 5°C. On a mild 22°C day, it doesn't need to — 12°C water is enough. The controller adapts to whatever temperature the heat pump delivers, so your system runs at peak efficiency whatever the weather.
Load compensation
Why warmer water is smarter
Most cooling systems run full blast regardless of conditions. Load compensation means your heat pump only works as hard as it needs to — saving energy and reducing noise.
Full power needed to overcome high outdoor temperatures.
Less energy, less noise, same comfort.
No setup required
Plug in and cool down
The load-compensated controller is pre-installed in every fan coil unit we sell. There's no separate box to wire in, no commissioning, no programming. Connect your FCU to the chilled water circuit from your heat pump, set your target room temperature, and the controller handles everything else.
