Notes:
(1)
the unit of measurement depends on P2
(2)
Properly set the parameters corresponding to the regulators after setting parameter P2
(3)
The formula for the calculation of the CPT temperature is:
CPT temperature = {[(P7) x (temperature detected by the inlet air probe)] + [(100 - P7) x (temperature detected by the outlet air probe)] : 100}
(4)
the unit of measurement depends on P9 and P10
(5)
the value depends on parameter P2 (0,1 °C or 1 °F)
(6)
if parameter r12 is set to 0, the compressor will be switched on when the room temperature or CPT temperature is above the "working set-point + r0" and will be switched off when the
temperature falls below the working set-point; if parameter r12 is set to 1, the compressor will be switched on when the room temperature or CPT temperature is above the “working set-point
+ r0/2” and will be switched off when the temperature falls below the "working set-point - r0/2”
