DIFFERENTIAL THERMOSTAT--HP52

Solar heating, temperature comparison

General Description


HP52 is a differential thermostat for independant monitoring and control of temperature in 2 zones with respect to their temperature difference.

A sensor in each location is used to give the temperature difference.


2 thermistor sensors are supplied with ranges of

-50.0/115.0 Deg.C  or  -58.0/239.0 Deg.F.


Available as 96 x 96mm front panel mounting or IP54 surface/wall mount, it's large 20mm display makes for easy reading.


With 0.1 Degrees resolution, adjustable hysterisis from 0.2 Deg. and scale in C or F, the result is a versatile accurate differential thermostat.

Supplied with 2

sensors

Applications.


  • Solar heating

  • Ground sourced heat  pumps.

  • Crop stores, free cooling.

  • Dual source heating,

  • Process selection
