 Small flat-blade screwdriver
 1/4-inch hex drill/driver set
 Marker or pencil
 Torque wrench
 ESD wrist strap
Prerequisites
 Wiring conforms to NEC and local codes and
regulations. For further information see the
Wiring Guidelines Manual (125-3002).
 (Optional) Room temperature sensor installed.
 24 Vac Class 2 power available.
 Supply power to the unit is OFF.
 Any application specific hardware or devices

plugs into the RTS port on the
controller, providing
temperature input and actual
space control until a permanent
RTS is installed.
Installation Instructions
 Use earth ground isolating step-down Class 2
transformers. Do not use autotransformers.
Determine the supply transformer rating by summing
total VA (3.5 VA per unit) of all actuators used. It is
recommended that one transformer power no more
than 10 actuators.
1. Determine the size of the damper shaft by doing
one of the following:
- If the damper shaft is 1/2-inch, proceed to
Step 2.
NOTE: The actuator comes with a factory
installed 1/2-inch damper shaft guide.
- If the damper shaft is 5/8-inch,
