| Overview
IdroCONTROL is a Fan Coil Unit (FCU) controller designed to control individual zones in commercial building applications. The controller supports 2-pipe and 4-pipe FCU applications and provides control of connected HVAC equipment through configurable inputs and outputs.
IdroCONTROL can control functions such as:
- Water valves ON/OFF
- 3-stage fan speed control and 0–10 V modulating fan control
- Electric heat (auxiliary heating)
- Fresh-air dampers
- Connected sensors and other field devices
The controller operates as part of the 75F building automation ecosystem and can communicate with the Central Control Unit (CCU) and Building Management System (BMS) through supported communication interfaces.

| Mounting
⚠️ Warning: Failure to de-energize the controller before installation or removal may result in electrical shock, equipment damage, or injury.
IdroControl should be installed on a DIN rail. To lock the DIN clip to IdroControl, use the screws provided to the back of the IdroControl. The DIN clip is spring-loaded, engage the lower end of the DIN clip onto the rail and slightly push upwards to compress the spring of the clip, pivot the device towards the DIN rail and release. The DIN clip will lock into position & hold the device firmly.
| Position Number | Part Description |
1 | IdroNode |
2 | DIN Clip |
3 | Screws to Lock DIN Clip |
4 | DIN Rail |
- Secure the DIN clip to the rear of the IdroCONTROL controller using the supplied screws.
- Position the controller against the DIN rail.
- Press the controller toward the rail until the spring-loaded clip engages with the DIN rail.
- Verify that the controller is securely attached to the rail.
- Confirm that the controller does not move or detach when light manual pressure is applied.
| Wiring
- To wire the IdroControl, remove the insulation of the cable for about 7 mm (a little over ¼ inch), lift the flap, insert the wire and push the flap down. Try pulling the wire out to make sure it is firmly snapped in place. Refer to the image for a visual aid.
- To remove the wire, lift the flap up and pull the wire out.
| Controller Removal
- Verify that the IdroCONTROL controller is de-energized.
- Locate the spring-loaded DIN-rail clip on the rear of the controller.
- Release the DIN-rail clip using the appropriate method for the installed hardware. If required, use a small flat-blade screwdriver
- While holding the clip in the released position, move the controller away from the DIN rail.
- Tilt the controller away from the rail and remove it.
- Support the controller during removal to prevent excessive force on connected wiring.
- Inspect the controller, DIN clip, and mounting hardware for damage before reinstalling.
