The ambient temperature of a room is controlled in the heat mode by a heater and a fan, and in the chill mode only by the fan. A heat sensor provides a 0-10 V signal.
A switch is used to deactivate temperature regulation.
The direct evolution of inputs and outputs can be monitored in a supervision window.
Description of the inputs/ouputs:
The temperature is supplied by a sensor with output voltage of 0 to 10 V.
Model Required:
Zelio Logic with analog inputs.
SR2 B121 BD (24 V DC) or SR2 B121 JD (12 V DC) for example.
Program Description:
Input I1 =0 : regulation is off.
Input I1 =1 : Regulation is on.
Input I2 =0 : chill mode.
Input I2 =1 : heat mode.
Hysteresis:
Advantages of the application:
Use of 0-10 V analog inputs.
The supervision window.
