Have a JCI C500aac controller in a unit and the unit is using those r81 kits on the valve actuators.

Wanting to put a spyder on the unit and was wondering if the spyder can be used to operate those r81 kits on the actuators.

The drawing I have calls the wiring controlling the actuator the level 1 bus and Im wondering if the c500 actually communicates with the r81 or if it just sends out a proportional signal.

If a proportional signal cannot be sent to the r81 Im also wondering if it would be feasible to just remove the r81 module and connect directly to the actuator motor with 24vac using floating point.

Any suggestions would be greatly appreciated.
