Digital / Analogue outputs test
Aw
Condenser fan 1 OFF/ON/% OFF/0 The condenser(s) fan(s) are basically driven by the compressors ON/OFF. But if they Condenser fan 2 OFF/ON/% OFF/0 are driven by analog outputs, they can be tested with an analog value.
Analogue outputs Ax
Economizer opening % 0 0 100 (option)
Hot water valve % 0 0 100 Hot water coil proportionnal valve (option)
Gas outlets Ay
