[. . . ] Insert provided hole plug in HS-Series junction box in opening opposite UC1 whip. MULTIPLE APPLIANCE INTERLOCKS To interlock with one additional 24/115 VAC heater add the MAC1E. 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 more than two 24/115 VAC heaters, add the MAC4E for a total of up to 5 heaters. It is powered by and communicates with the UC1 through a factory wired whip. Consult factory for installations with more than 5 heaters. To interlock a millivolt water heater and a 24/115 VAC furnace or boiler, add the WHKE and MAC1E. MILLIVOLT INSTALLATIONS Each millivolt appliance interlocked with the UC1 must have its own WHKE kit installed. The WHKE Gas Pressure Switch actuates the Venter through the A - B Dry contacts. The Linear Limit switch disables the heater in the event of a venting malfunction. IMPORTANT: Each millivolt appliance interlocked with the UC1 must have its own Linear Limit spill switch. MULTIPLE MILLIVOLT HEATER INSTALLATIONS Multiple millivolt heaters can be installed by using the A-B dry contact terminals of the UC1, MAC1E or MAC4E. Wire each WHKE gas pressure switch in parallel across A-B terminals of UC1, MAC1E or MAC4E. Wire Linear Limit safety switch into each individual millivolt heater. For further information consult factory or WHKE instructions.
