Wiring for all eld connections must be run through the
available electrical conduit to the low voltage box at the
back of the unit. See Figure 18.
Refer to Figure 20 in reference to Sections 7.E.1 thru
7.E.10
7.E.1 Power
Boiler Pump – If connecting a boiler contactor or pump,
use terminals 23 (neutral) and 24 (line voltage). The
output of these terminals is 120VAC with a maximum
output current of 1.5 amps. Boiler pump functionality is
congured using the touch screen.
Auxiliary – no functionality is available on this unit.
7.E.2 Dry Contacts
DHW Pump - If connecting a domestic hot water (DHW)
pump, use terminals 27 and 28 (See Figure 20). This is
a dry contact. The DHW pump supply voltage or DHW
pump relay coil voltage should be applied at terminal
27, and when the DHW pump is called, would be switch
to terminal 28. Contact ratings are 250VAC, 1.5A
