The MAC-4 multiple appliance controller can interlock up to four appliances with power venters, draft inducers, or combustion air intakes, doing away with difficult or costly wiring jobs, says the manufacturer. Variable voltage input (18 to 30 vac) readily interlocks with 24- and 115-vac control systems for gas and oil burners, eliminating the need for voltage-specific relays, says the company. The circuit board is housed in an oversized, 18-gauge electrical box with multiple knockouts.

Tjernlund Products, Inc., 1601 Ninth St., White Bear Lake, MN 55110-6794; 800-255-4208 or 651-426-2993; 651-426-9547 (fax); www.tjernlund.com (website).
