As the years went by we expanded the number of power venter models to include a variety of these interlock controls. [. . . ] The models HSUL-J, HSUL-1, & HSUL-2 will still be available through 2002. The UC1 will be the standard (optional) accessory interlock control for the following models: DJ-3, D-3, I, IL, XL (These models will still require the PS1505 Fan Proving Switch) PAI-3, PAI-4, PAI-5, PAI-6, PAI-7 Interlocking the UC1 with multiple or millivolt appliances: New millivolt and multiple heater interlock controls that end with "E" will be similar to previous versions, but designed to easily interface with the UC1 control. To interlock with one additional 24/115 VAC heater add the new MAC-1E. It is a stripped down auxiliary board version of the UC1 and is powered by and communicates with the UC1 through a factory-wired whip. To interlock with a millivolt water heater only, add the WHK-E water heater interlock kit. To interlock a millivolt water heater and a 24/115 VAC furnace or boiler, add the WHK-E and the MAC-1E. To interlock more than two 24/115 VAC heaters add the MAC-4E for a total of up to 5 heaters. It is powered by and communicates with the UC1 through a factory wired whip.
