Setpoint Screen #28 - Adaptive Defrost Adj.

Setpoint

SA Unit Spts ID 102

Adaptive Defrost

Adj. Setpoint: 0 MIN

Enter a value greater than zero to enable the Adaptive Defrost Adjust-

ment of the Heat Pump Defrost Timer (Screen #27). This adjustment

value will be subtracted from the Heat Pump Defrost Timer if the Defrost

Mode lasts the entire 10 minutes. A proportion of this adjustment value

will be added to the Heat Pump Defrost Timer if the Defrost Mode only

lasts between 8 minutes and 0 minutes. This screen only applies if using

the SA Controller and a Head Pressure Module. This screen does not

appear if using the SA Controller and a WSHP Protection Module in a

Water Source Heat Pump application.

Internal Schedule

Optimal Start Soak

Multiplier: 0.0

The Internal Schedule Optimal Start Soak Multiplier Setpoint is a multi-

plier that if set to a number greater than 0 will be used as a multiplier for

calculating the Optimal Start Time for the HVAC unit. This multiplier

is only applied if the unit has been off for more than 24 hours. See the

SA Controller Technical Guide for more detailed information regarding

the Optimal Start. This multiplier is only applied if you are using the

SA Internal Schedule.

Setpoint Screen #31 - Sensor Calibration for

SPC & SAT

SA Unit Spts ID 102

Sensor Calibration

SPC: XX.Xº 0.00º

SAT: XX.Xº 0.00º

If the Space or Supply Air Temperature Sensors are reading incorrectly,

you can use this option to enter an offset temperature to adjust the Sen-

sor’s Temperature. Enter a positive Sensor Calibration value to raise the

Space Temperature and/or Supply Air Temperature Sensor reading and

a negative value to lower the Sensor reading.

Description Minimum Default Maximum

Sensor Calibration SPC -100.0ºF 0.0ºF +100.0ºF

Sensor Calibration SAT -100.0ºF 0.0ºF +100.0ºF

Setpoint Screen #32 - Sensor Calibration for

EAT & EWT

SA Unit Spts ID 102

Sensor Calibration

EAT: XX.Xº 0.00º

EWT: XX.Xº 0.00º

If the Entering Air or Entering Water Temperature Sensors are reading

incorrectly, you can use this option to enter an offset temperature to

adjust the Sensor’s Temperature. Enter a positive Sensor Calibration

value to raise the Entering Air or Entering Water Temperature Sensor

reading and a negative value to lower the Sensor reading.

Description Minimum Default Maximum

Sensor Calibration EAT -100.0ºF 0.0ºF +100.0ºF
