WARNING!
Never jumper terminal “A” from CXM or DXM
board #1 to CXM or DXM board #2 on multi-compressor/
control bound units. See Figure 5 in electrical section of this
document for motorized valve wiring.
Accessory Connections -
A terminal paralleling the
compressor contactor coil has been provided on the CXM/
DXM control of the TMW line. "A" has been provided to
control accessory devices, such as water valves, electronic
air cleaners, humidifiers, etc. Note: This terminal must be
used only with 24 Volt signals and not line voltage signals.
This signal operates with the compressor contactor. See
Figure 8 or the wiring schematic for details.
24 Volt Accessory Wiring
These terminals may be used to
power 24 volt water valves on
units size 036, 060
