VMA replacement wiring diagram
Consider the following information when replacing
a VMA1410, VMA1415, VMA1420, and the VMA1440
controller with a VMA18 controller.
The VMA142x controller has five binary outputs
(BOs) and internally supplies 24 VAC. The VMA18
controller has three binary outputs (BOs) and
supplies 24 VAC to these BOs. The VMA18 controller
has two configurable outputs (COs) and these two
COs require an external low voltage power source.
Refer to
Variable Air Volume Modular Assembly (VMA)
1400 Series (LIT-635058)
for the Input/Output (I/
O) point differences between the VMA1410 and
VMA1420.
See the following figure for wiring instructions.
