MAC4E WIRING CONNECTIONS WITH UC1 UNIVERSAL CONTROL
Remove power to UC1 and heating equipment when making connections from the MAC4E to the UC1 or installing, servicing or changin
g dip switch settings in the UC1.
Failure to do so may result in personal injury and/or equipment damage.
The Power LED (RED) on UC1 or any LED’s on UC1 or MAC4E
should not be on.
See UC1 Universal Control wiring section of Venter or UC1 instructions for 24 VAC, 115 VAC or Millivolt (Dry Contact) appliance interlock diagrams. The MAC4E and UC1 Universal Control appliance interlock steps and diagrams are identical. IMPORTANT:
Venter Fan Prover must be wired to P1 & P2 safety circuit in UC1. Do not
supply power to P1 & P2 or damage will result.
The MAC4E contains four appliance
interlock blocks which are identical. Each appliance interlocked with the MAC4E and UC1 must have the Red voltage jumper on th
e proper 115V, 24V or DRY position based
on appliance interlock voltage.
