NOTE: The voltage should be measured at the field
power connection point in the unit and while
the unit is operating at full load (maximum
amperage operating condition).

Five (5) wires should be run from thermostat subbase
to the 24V terminal board in the unit. A five
conductor, 18 gauge copper, color-coded thermostat
cable is recommended. The connection points are
