Bus Coupler 3 External sensor KNX insert

Product code: 200900
This product is essentially the same as the standard 200800 bus coupler but the additional screw terminals for an external temp sensor work with the Gira 514200 and 514500 temperature regulators only.
Price (Excluding GST)


Used for the coupling of the GIRA KNX application modules with programming buttons to KNX systems

Note, GIRA bus couplers will only work with GIRA push buttons and RTC's due to the mechanical fit and hardware ID's.
