Several motors can be connected to the controller in parallel. The sum of the single motor currents
must not exceed the rated current of the controller.
Installation instructions
The motor cable is wired in parallel e.g. in a terminal box.
Each motor must be equipped with a thermostat (NC contact) the series connection of which
must be connected to X2/T1 and X2/T2 using a separate cable.
Only use shielded cables ( 4−6). Connect the shield to PE with a large surface.
