Argo offers a broad line of controls for water heating and multiple zone boiler heating applications.
Please check out our web site at http://www.argoindustries.com for applications information and comprehensive wiring
diagrams.
A typical wiring diagram is shown below. This is a multi-zone application using zone pumps with programmable domestic
hot water priority using our ARM-4P Panel.
Product features include:
1.
Built in transformer that will support up to 15 zones. Transformer has electronic fuse protection to prevent
transformer overloading.
2.
Data Port Terminal for easy connection to other Argo control products.
3.
Expansion module plug-in allowing easy expansion to more zones.
4.
Priority Zone Safety Timer. If the priority zone calls for more than 30 minutes the priority zone feature will turn
off allowing all zones to operate independently preventing freeze ups if water heater has a problem.
