Accessory Connections

A terminal paralleling the compressor contactor coil 
has been provided on the DXM2 control. Terminal “A” is 
designed to control accessory devices. Note: This terminal 
should be used only with 24 Volt signals and not line voltage. 
Terminal “A” is energized with the compressor contactor (see 
Figure 27).
