Use 15 m installation cable
If Uponor Interface I-75/76 is more than 2 m from Uponor 
Controller C-55/56, use the 15 m four-wire connector cable or 
similar, as shown in the fi gure below.
To wire Interface I-75/76 to the Controller C-55/56 using the 
15 m connector cable:
1  Insert a thin screwdriver to open the relevant push-wire 
connection.
2  Push in the wire.
3  Remove the screwdriver.
4  When all wires are connected, fasten the cable in the cable 
clamp.
  Note that the wiring is polarized, so wire 1 on the 
controller must be connected to 1 on the interface, and 
so on.

5.2  Optional: connect multiple controllers
  Note that multiple Uponor Controller C-55/56 units 
require software programming.
Up to three controllers can be connected to the same Uponor 
Interface I-75/76. All controllers require an antenna, as shown 
in the illustration below.
In the illustration:
•  Controller 1 is the controller connected to the interface
•  Connect terminals 5 and 6 of controller 2 to terminals 5 and 
6 of controller 1.
•  Connect terminals 7 and 8 of controller 3 to terminals 7 and 
8 of controller 1 or controller 2.
To connect up to three controllers to the interface:
1  Check that the wiring is complete.
2  Check that the 230 V compartments are closed.
3  Connect controllers 2 and 3 to AC power.
4  Check that the 230 V compartments are closed.
5  Connect controller 1 to AC power.
  Note the polarity of connections between the 
controllers.
