7.D Field Connections
Wiring for all Field Connections must be run along the
inside face of the available electrical raceway to the
back of the unit. See Figure 17.
7.D.1 Power
Boiler Pump – if connecting a boiler contactor or pump,
use terminals 17 (neutral) and 18 (line voltage). The
output of these terminals is 120VAC with a maximum
output current of 1.5 amps. Boiler pump functionality is
configured using the touch screen.
Auxiliary – no functionality is available on this unit.
7.D.2 Dry Contacts
DHW Pump - if connecting a domestic hot water (DHW)
pump, use terminals 21 and 22 (See Figure 19) as this
is a dry contact, the DHW pump supply voltage or DHW
pump relay coil voltage would be applied at terminal
21, and when the DHW pump is activated, would be
