Unit Controls: Operation and Wiring
Your unit is equipped with 12 VDC and 24 VAC removable terminal blocks. The control logic of the unit
circuit board is such that the most recently used remote control will control the unit. If desired, 12 VDC
and 24 VAC controls may be used in the same installation. Use a 3 mm flat-head screwdriver to connect
wires to the terminal blocks.
