IMPORTANT
It is recommend to install a fuse on the secondary side
of the transformer in order to protect the devices from
miswiring.
If the distance between the controller and actuator or sensor
with 24 Vac supply is greater than 550 ft (170 m), a separate
external transformer for the actuator or sensor is necessary.
