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.
