Below are operations manuals for the Robertshaw SlimZone Classic and Deluxe control panels as seen in our catalog. There is a lot of information in these manuals that will answer whether or not these panels are right for your application.
If you have multistage equipment, have more than 3 Zones, or are interested in future expandability look at the Deluxe. If you have single stage equipment and just need 2 or 3 zones, the Slim Zone Classic or the EWC NMC will be your best value.
The Durozone RED-4 will support up to 4 zones with 3H/2C, 2H/2C+Heat Pump capabilities. See below for more details.
If looking for a panel that can handle single stage, two stage, dual fuel and heat pumps, for zone control up to seven zones, the BMPlus series control panel would be a good choice.
