Description

L1

(120VAC)

1

Location for connecting line voltage of the power supply. Note; most installation codes
require the installation of a service switch to break line voltage to the appliance.

PUMP A

2

120VAC output to the DHW circulator; powered during a demand for DHW.

PUMP B

3

120VAC output to the Boiler circulator; powered during all demands; DHW, local Central
Heat (CH1) and Lead-Lag Central Heat [CH2 (LL)]. This output is not used for all
plumbing configurations, see Section 10.0.

PUMP C

4

120VAC output to the Central Heating circulator; powered during a demand for local
Central Heat (CH1) or Lead-Lag Central Heat [CH2 (LL)].

L2

(Neutral)

5

Location for connecting neutral of the power supply and all circulators.

6

Ground

7

Location for connecting earth ground and for grounding all of the circulators.
