If you have a airhandling unit designed as a cabinet, the connections are located on the top of the unit, at the front between the duct connections. If you have a unit mounted in the ceiling or installed on a wall, for example a CL-type unit, the connections are located on one of the long sides. In many cases, these connections may be hidden behind an enclosure. In such cases, an inspection hatch should be installed to provide access to the connections.

If the ventilation unit is locked to one speed, it is usually because something is overriding the control system. This may, for example, be a humidity sensor, a pressure switch, a kitchen hood, or another type of external control that temporarily has priority. To identify the cause and ensure correct operation, it is recommended to contact a service company or the installer of the system.

The wireless handle contains a battery, which may be depleted or defective. Try replacing the battery with a new, high-quality battery and test the function again. In many cases, this will resolve the problem.
