House Codes
All of your X-10 modules, controlled by your HMS 1100, must be set to a House Code. A House Code can have 16 unit numbers. The House Code is set on each module using a dial. House codes are letters A through P.
Unit Numbers
Each module has its own Unit Number. Any unit number that is not being used for an ALC Switch Module may be used for an X-10 Module. ALC Switch Modules and X-10 Modules can not be assigned to the same unit number.
Each ALC switch module must have a unique address. ALC switch modules on the same branch can NOT have the same address. ALC Modules have 31 possible addresses, 1 through 31.
More than one X-10 Module can have the same unit number if you want to control multiple lights with the same unit number. X-10 Modules have 16 possible unit numbers, 1 through 16.
HMS 1100 systems have 511 unit numbers. They consist of ALC and X-10 module unit numbers, hardwire voltage output unit numbers, and internal flag unit numbers as follows:
