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.
