Documentation

How it works

1. 1When the unit is powered, the display shows the sensor temperature and the output status: green off, red on.
2. 2Holding PROG for 5 seconds gives access to the setpoint, the hysteresis and the trip point of each alarm; the arrows change the value and PROG confirms it.
3. 3The setpoint changes in 0.5 °C steps. When the temperature reaches an alarm value, its LED lights up.
4. 4If the sensor is cut or short-circuited, the output is switched off, the NTC indicator lights up and an error message is shown.
