2. The display changes to ready “ENTER MENU CODE”,
with four (4) zeros below it.

Configuration of the cascade
When installed in a Cascade system, the individual controls must
be programmed for cascade operation. This is accomplished by
accessing the control parameters.
Input the Installer code as described in the Copper-fin 2 Service
Manual. Once the control parameters have been accessed, use
the DOWN arrow key to select the H Control Mode parameters.
Press the ENTER key to access these parameters. Use the UP
arrow key to access parameter H4 Cascade. Press the ENTER
key to access this parameter. Use the DOWN arrow key to select
Enable. Press the ENTER key to program this into the control.
Press the EXIT key, then press the DOWN key until I Cascade
is selected.
Press the ENTER key to select the parameter I1 BLR Address.
Press the ENTER key to access this parameter. Each unit in the
Cascade system must be programmed with its own address.
The unit designated as the Leader will have an address of 0.
The remaining units in the Cascade will be Members and have
addresses from 1 - 7. Use the UP and DOWN arrow keys to
select the appropriate address. Press the ENTER key to program
this into the control.
Press the MENU key twice to exit the control parameters. Repeat
this procedure for all appliances in the Cascade, designating the
