When installed in a Cascade system, the individual controls must be programmed for cascade operation. This is accomplished by accessing the control parameters.

Press the [MENU] key for at least five (5) seconds. Input the Installer code as described in the Armor Service Manual. Once the control parameters have been accessed, use the NAVIGATION dial to select the Control Mode parameters. Press the NAVIGATION dial to access these parameters.

Rotate the NAVIGATION dial to select the parameter “Cascade Address”. Press the NAVIGATION dial to access this parameter. Each appliance in the Cascade system must be programmed with its own address. The water heater designated as the Leader will have an address of 0. The remaining water heaters in the Cascade will be Members and have addresses from 1 - 7. Rotate the NAVIGATION dial to select the appropriate address. Press the RIGHT SELECT [SAVE] key. If installing the water heaters in an existing system, the new water heaters should be programmed as the Leader and/or the higher number addresses.

Press the RIGHT SELECT [HOME] key to upload the address into the control. Repeat this procedure for all water heaters in the Cascade, designating the Leader control and the Member controls.

Note: A tank sensor must be installed when operating Armor water heaters in Cascade.
