Digital temperature regulator
|HD4032||Digital LED ON/OFF temperature regulator|
This is a temperature controller thermostat regulator with an analog output and an ON/OFF
The analog output is in current 4 ... 20 mA (4 mA -L -20oC, 20 mA = +80° C).
The setting of the intervention temperature (set point) is carried out by pressing the button on the left of
the front panel of the instrument and turning the knob on the right until the temperature at which the
relay contact is to open is shown on the display.
Intervention hysteresis may be adjusted with a trimmer at the rear of the instrument.
The temperature sensor is a Pt100.
If it is connected with 2 wires with a section of 1 mm2, a reading in excess of 0.06° C/m is obtained.
In order to cut down error a three-wire connection is advised, with the third wire connected to terminal 2.
The thermostat may be used either for heating or for cooling, simply by moving the jumper at the rear of
When the jumper is in HEATING position, the relay is energized if the probe temperature is lower than the
set temperature; when the jumper is in COOLING position, the relay is energized if the probe temperature
is higher than the set temperature.
