DHWG Domestic Hot Water Generator
Electrical Wiring:
1. Make all wiring connections to the DHWG system as
shown in Figure 4.
2. Wire the DHWG system circulator’s junction box leads
to
the boiler’s “DHW CIRC” line voltage terminals. Use 14
gage conductors in BX or conduit, secured to the
connectors provided (See figure 5).
3. Wire the DHWG system water flow switch to the
boiler’s “DHW T-STAT” low voltage terminals. (terminal
#3 and #4 of boiler low voltage terminals, See figure 5).
4. Refer to the boiler manual’s “Electrical Wiring”
section, for proper installation of all additional wiring
necessary for the space heating system and operation
of the boiler.
System Settings:
Refer to the boiler manual’s “Boiler Control and Display
Features”, in the “Operating Instructions” section, for
setting the boiler parameters properly to operate with the
DHWG system.
1. The domestic hot water post pump time (see Table 5 of
the boiler manual) should be set for the minimum value
of 1 second, when the alternating letter indication of
“P-d” is selected.
2. The domestic hot water mode must be set for # 2
(see Table 5), when the alternating letter indication of
“d-t” is selected.
3. The priority mode must be set for 0, DHW priority with
no time limit (see Table 5), when the alternating letter
indication of “b-t” is selected.
4. Set all other parameters as appropriate for the space
heating system and operation of the boiler.
