e:: Not all of these features may be required for your

unit, check electrical schematic.

Discharge Temperature Limit (DTL)

The control’s sensor is located on the discharge line.
This device will shut off the compressor and the
outdoor fan(s) if the discharge temperature exceeds the
DTL setting. Once the discharge temperature has
returned to normal, the compressor will cycle back on.

Low Outdoor Ambient Cooling

All Odyssey units with Symbio

700 controls have

cooling capabilities down to 0°F as standard. At
temperatures below 50°F, some reduction in cooling
capacity can be expected. When the optional Low
Ambient Accessory kit is field installed, the full capacity
of the unit is available down to 0°F.

Evaporator Defrost Control (EDC)

This control is located in the Air Handler. The control’s
sensing tube is embedded vertically in the evaporator
coil, near the center. This device will stop the
compressor if the indoor coil temperature drops below
its setting. The indoor air will still circulate across the
coil bringing the temperature of the coil back up to the
cut-in temperature of the evaporator defrost control.

Low Pressure Cut-Out (LPC)

This control’s sensor is located in the suction (gas) line,
near the compressor. This control will stop the

compressor and the outdoor fans if suction pressure
drops below the Low Pressure Cut-Out setting. Once
the suction pressure has returned to normal, the
compressor and outdoor fans will cycle back on.

High Pressure Cut-Out (HPCO)

This control’s sensor is located in the discharge line.
This device will shut off the compressor and the
outdoor fan(s) if the discharge pressure exceeds the
High Pressure Cut-Out’s setting. Once the discharge
pressure has returned to normal, the compressor will
cycle back on.

Internal Overload Protector (IOL)

This device is embedded in the compressor. It will shut
off the compressor if the discharge temperature of the
compressor exceeds its design trip temperature.

N

No

otte

e:: The IOL will put the compressor back in

operation once the compressor motor heat has
dropped below the trip setting; however, a check
of the refrigerant and electrical systems should
be made to determine the cause and be
corrected.
