Motion Sensor Type*’
This setting defines which type of motion sensor is being used:
- 0 = Other brand motion sensor
- 1 = AoFrio motion sensor
- 2 = Other brand motion sensor, Activity will not bring the cooler out of standby modes
- 3 = AoFrio motion sensor, Activity will not bring the cooler out of standby modes
Motion sensor requires 3 motion counts in 30 min to exit a standby mode.

- beta value use in each NTC type
- resistance at 25°C for each NTC type
Two different NTC types can be used simultaneously.
NTC 1 Beta value

Ad4 | Integers | 1-2 | 1 |
AD5 NTC Type
Digital display | Increments & units | Parameter range | Default |
Ad5 | Integers | 1-2 | 1 |
NOTE: AD5 is normally used as an analog input, digital input, or digital output. It has a minimal PWM output which means it can't be fully turned off (in terms of power/electricity).
In rare situations where it is used as a lighting connection for the SCS Controller there will be a minimum 5% ‘on time' duty, meaning it the connected light will be 'slightly dim’ rather than fully 'off'.
