The optional electric heater overlaps with the chilled-water heat by 22° F (12.2° C). The heater turns on when heat is required
and remains on until the chilled-water temperature exceeds the ambient by 22° F (12.2°C) or until the room temperature is
satisfied. During very cold conditions electric heat overlaps the chilled-water heat to supplement heating. Note that parameter
P-19 setting increments are in °F even when the control is set to display °C.
