Tjernlund MAC1E is used in conjunction with the UC1 universal control to interlock one additional 24 VAC, 115 VAC or millivolt controlled appliance. Millivolt appliances require a WHKE kit. Powered by and communicates with the UC1 through a factory wired whip. It activates the inducer/blower through its connections to the UC1, and in turn relies on the UC1 fan prover safety circuit (P1 and P2) to allow its interlocked appliance to operate. Any pre/post-purge settings on the UC1 will be defaulted to the MAC1E.

• The MAC1E puts an end to difficult and costly job site wiring nightmares
• Circuit board housed in oversized 18 ga electrical box with multiple knock outs for easy wiring connections
