Enables Appliances to be Interlocked in Conjunction with UC1 universal control
The MAC4E is used in conjunction with the UC1 Universal Control to interlock up to four additional 24 VAC, 115 VAC or millivolt (Dry Contact) controlled appliances. It activates the Venter through its connections to the UC1 and in turn relies on the UC1 Fan Prover safety circuit (P1 & P2) to allow its interlocked appliances to operate. Any pre/post-purge settings on the UC1 will be defaulted to the MAC4E. Two LEDs for each appliance interlock block are provided on the MAC4E. LEDs #1, 3, 5, 7 (AMBER) shows an appliance call for heat. LEDs #2, 4, 6, 8 (GREEN) shows that the burner is approved to fire after the Venter Fan Prover safety circuit through the UC1 is completed. The MAC4E also has an LED #9 (RED) which means power is supplied to the MAC4E through the UC1.
