ACCESSORY CONNECTIONS
A terminal paralleling the compressor contactor coil has been
provided on the DXM2.5 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 29).
The DXM2.5 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.
