Prozeda Primos 250 SR - Setting the Heating Function; Temperature Difference Controller Function

Setting multi-function controllers (MFC)

temperature rises above the upper limit of the preset temperature range (hysteresis), the
switching output of the multi-function controller switches off.
The "Basic settings" menu allows you to set the following parameters:
• P:30: MFC R4 function at switching output R0
• P:31: Selection of the sensor for the source for MFC R4
The "Program" menu allows you to set the following parameters:
• Switch-on temperature of the "Heating“ function
• Hysteresis of the "Heating" function
• Time window 1 (2, 3): Start
• Time window 1 (2, 3): Stop.
8.3 Setting the "Temperature difference controller"
function
In the case of the "Temperature difference controller" there is a measurement point at both
the source and the sink. If the difference between the temperatures of the two
measurement points exceeds a predefined value, the switching output of the multi-function
controller switches on.
In addition, a minimum temperature can be set at the source and a maximum temperature
at the sink. If the maximum temperature is exceeded or the temperature falls below the
minimum temperature, the switching output of the multi-function controller switches off.
The "Basic settings" menu allows you to set the following parameters:
• P:30: MFC R4 function at switching output R0
• P:31: Selection of the sensor for the source for MFC R4
• P:32: Selection of the sensor for the sink for MFC R4
The "Program" menu allows you to set the following parameters:
• Maximum temperature Tmax of the sink for the "Temperaturedifference controller"
function
• Minimum temperature Tmin of the source for the "Temperaturedifference controller"
function
• Switch-on difference dTmax for the "Temperaturedifference controller" function
• Switch-off difference dTmin for the "Temperaturedifference controller" function
• Time window 1 (2, 3): Start
• Time window 1 (2, 3): Stop.
