cellar, but the air probe must be located inside the wine cellar.
2) The air probe shall be located in the wine cellar 5 ft above the floor or the air
return area, but it shall not be located in the air supply area or other areas
where air is not circulated.
3) Air probe can be pulled out of the temperature controller around 5 ft; if
additional wires are needed, 18 gauge wires may be used to extend the air
probe.

Suction pressure setting: Cut out=5 psig; Cut in=25 psig; Differential=20 psig
Head pressure setting: Cut out=230 psig; Cut in=150 psig; Differential=80 psig
It may need to adjust the setting in the field to get the right cycle time.
