18 LAO Unoccupied Cooling Room Set Point. Water Source Heat Pump

attempts to maintain room temperature by discharging a constant

temperature of air. For cooling, typical discharge temperature is

room temperature minus 20°F. Unit begins cooling based on room

temperature. If unit is in unoccupied time period, Set Point attempts

to maintain room temperature between unoccupied Set Points. If

room Set Point Adjustment is active, Set Points are adjusted based

on value of Set Point Adjustment (Point 10).

0 – 255°F
