Description
L1
(120VAC)
Black
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.
L2
(Neutral)
White
Location for connecting neutral of the power supply.
Ground
Green
Location for connecting earth ground and for grounding all of the circulators.
Low Voltage Connections
The Matrix low voltage (thermostat) connections are located on a terminal strip on the left-hand side of the unit,
on the outside of the boiler cabinet. Low voltage field connections are to be installed in accordance with Figure
12-2 and Table 12-2.
Fuse (24 VAC)
– The Matrix is equipped with a “blade style” 2 Amp fuse to protect the internal transformer
located on the control panel.
The Matrix terminal strip is for low voltage (max 24 VAC) and low load (max 1 Amp)
connections. Any electrical loads in excess of 24 VAC or 1 Amp must be isolated using
relays. Failure to follow these instructions can result in component malfunction.
