WARNING: ISOLATE THE MAINS SUPPLY BEFORE

COMMENCING INSTALLATION

As the C-Stat is a wireless product with no electrical connections

all electrical wiring will be made to the ASR-ZW receiver.

All necessary electrical connections should now be made. Flush

wiring can enter from the rear through the aperture in the

backplate.

The mains supply terminals are intended to be connected to the

supply by means of fixed wiring.

The receiver is mains powered and requires a 3 Amp fused spur.

The recommended cable size is 1.0mm².

The receiver is double insulated and does not require an earth

connection, an earth connection block is provided on the

backplate for terminating any cable earth conductors. Earth

continuity must be maintained and all bare earth conductors

must be sleeved. Ensure that no conductors are left protruding

outside the central space enclosed by the backplate.
