Temperature Regulator

Model  Description 
HD4034  HD4034 Digital LED ON/OFF temperature regulator

The HD 4034 temperature controller regulator thermostat is an ON/OFF regulator with relay output
(1 exchange contact 3A/22OV).
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 PT 100 probe. If this is connected with 2 wires and a cable with a section of
1 mm2 , a reading in excess of 0.006°C/m is obtained.
For long distances we advise a three-wire connection, with the third wire connected to terminal 2.
With the three-wire connection the line resistance is automatically compensated.
The thermostat may be used either for heating or for cooling, simply by moving the jumper at the rear of the instrument. 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.
