Six N.O. Boiler startup relay
outputs. Each is wired in series
with the boiler's limit circuit.
Six modulating outputs can be 0-5V,
0-10V, 1-5V, 2-10V, or 4-20ma. Go to
M4 or M4-CNC Startup Menu to
determine the type of output for each stage.
LED indicates the
associated relay status.
Connect to M4 or M4-CNC
and additional Extension panels to add
additional stages using phone style cable
(cable provided with M4-Ext).
Extension Selection Switch to determine
Stage letters and LED colors.
Ext-A Stages E - J and all LEDs are Green
Ext-B Stages K - P and all LEDs are Red
This switch is covered with the Wiring Enclosure.
