2.5.1. Supply cables
The TC02 controller requires a 12 to 24 VAC supply. The valve actuators may be rated
between 24 VAC and 230 VAC. The controller does not supply actuators. Sizing and fuse
protection of 230 VAC supply cables depends on the total load and on local regulations.

The controllers may be mounted in any orientation using metal Stand-offs, to suit the four
fixing holes, the minimum stand-off height is 5mm, 3 mm fixing screws are recommended.
