Temperzone Unit Controller 6 - Operation and installation- Hydronic
3.1.

Power supply terminals

The UC6 is powered by 24V ±10% AC. A class 2 safety transformer with a
minimum rating of 24VA must be used in the installation. The power supply to the
UC6 controller must not be used to power other electrical devices. If the 24V
secondary winding of the transformer is earthed then make sure that the earthed
wire connects to terminal "µPC supply 0V".
A yellow LED indicates when the UC6 is powered.
