There are 4 versions of the TUC-5R type controller, three of
which are still currently supported. The older voltage TUC-5R
controller is not supported anymore, and an upgraded replacement
is recommended. The older voltage TUC-5R controller is not
pictured here.
The early TUC-5R 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 early TUC-5R controller is generally used to
control small Roof Top Units, heat pump units, or complicated

VAV box control. The number -5R derives from the fact that
there are a total of 5 relay outputs on this circuit board. Typical
common applications of this TUC-5R controller are as follows:
Roof Top Units with up to 2 heat and 2 cool stages, heat pump
units, or complicated VAV box control such as hot duct, cold duct
applications, etc. WattMaster Controls has an extensive standard
library of application-specifi c software that has been developed
over the years for this TUC-5R 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.
