The RTU-17 controller is an application-specifi c controller. 
Please see the application specifi c manual for the exact input 
and output confi guration for the specifi c application that you are 
controlling. This RTU-17 controller is generally used to control 
Roof Top Units, hence the name RTU. The number -17 derives 
from the fact that there are a total combination of seventeen inputs 
and outputs on this circuit board. Common applications of this 
controller are as follows: RTU / AHU control, standalone limited 
schedule controller, standalone Lighting controller, etc. WattMaster

Controls has an extensive standard library of application-specifi c 
software that has been developed over the years for this RTU-17 
controller. WattMaster Controls can and will write application- 
specifi c software to your written specifi cations, for a nominal cost. 
This is usually done to satisfy a specifi c customer requirement. 
The jumpers JO2 “C”, “B”, and “A” must be off for RS-485 
communication connections to the SAT 3C controller.
