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).
The DXM2 controller includes two accessory relays ACC1
and ACC2. Each relay includes a normally open (NO) and
a normally closed (NC) contact. Accessory relays may be
configured to operate as shown in Tables 8 and 9.
