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.
