This application allows you to control the temperature and humidity using a PT100 signal on AI1 and a 0-10V signal on AI2 of the ATR401-24ABC controller. The regulation is in hot mode and is ON / OFF with 5 ° C of hysteresis on the temperature setpoint (relay Q1).
Alarm 1 is in absolute value and is activated above the set point with a hysteresis of 1 ° C for process 1 (temperature).
Alarm 2 is in absolute value and is activated above the setpoint with a hysteresis of 1% for process 2 (humidity).
The probe used is 2000.50.021. (Https://www.pixsys.net/it/prodotti/tras ... sm-umidita)
