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, humidifi ers, 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
