Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as
the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an
NRTL-listed power supply, many AHJs accept non-listed SELV devices.

The SK10-TC-ETF2 is an IP54/65 KNX temperature controller supplied with a PT1000 screw-in immersion probe for water tanks, buffer storage and hydronic piping. Seven probe lengths, from 50 mm (1.97 in) to 400 mm (15.7 in), let you match the insertion depth to the vessel or pipe.
All versions measure from -30 to +150 °C (-22 to 302 °F) with Class B accuracy and 0.02 °C (0.04 °F) resolution. The KNX module includes an integrated bus coupler and room temperature controller (RTR), runs from the bus without an auxiliary supply, and is configured in ETS with the HLK305 application.
