Operating Temperature
: 0 to 50 °C
Differantial controller gives output to calculate temperature difference between two sensor.
Easy access to the screen to adjust the setpoint and code protected the parameter menu
for parameter settings. If temperature difference between two sensor becomes equals or more
according to adjust setpoint and hysteresis parameter,the relay output is activated, otherwise
the relay output is disabled.
