Single Unit Application for MC4002 with Alarm Board
When connecting an MC4002 with alarm board to a single unit, the unit must be wired to the Unit 1 position on the
MC4002 board. A power loss alarm will appear for Unit 2. To eliminate this nuisance alarm, jumpers must be placed
from Unit 1 “R” terminal to Unit 2 “R” terminal and Unit 1 “C” terminal to unit 2 “C” terminal on the control board
(see Figure 21).
The control must be configured as follows: Number 8 “ALT” must be set to “NO”; Number 9 “LLCO” must be set to
“0”.
Wire the unit according to the correct diagram for the model being applied; see appropriate connection diagram.
