DEVIreg™ 330

DIN Rail Thermostats for Heating, Cooling and Temperature Control Applications

DEVIreg™ 330 is a range of electronic thermostats designed for DIN rail installation in electrical cabinets. The thermostats are used for temperature control in heating and cooling systems and are available in three temperature ranges to suit different applications.
Temperature measurement and control are performed using the supplied wired temperature sensor or a compatible indoor or outdoor air sensor. Installation must be carried out through an all-pole disconnection switch.
The thermostat incorporates a relay with both normally open (NO) and normally closed (NC) contacts. The output contacts are voltage-free and can be used in control systems with voltages up to 250 V.
LED indication provides visual status information for standby and heating operation.

DEVIreg™ 330 (-10 °C to +10 °C)

This version is designed for temperature control in lower temperature applications, including frost protection systems.
The thermostat is supplied with an outdoor temperature sensor and supports temperature adjustment between -10 °C and +10 °C.

DEVIreg™ 330 (5 °C to 45 °C)

This version is designed for applications requiring temperature control in the range from 5 °C to 45 °C.
Typical applications include:
  • Frost protection
  • Electric floor heating
  • Total heating via floor systems
  • Ground ice and snow melting systems
  • Roof frost protection
  • Pipe tracing
  • Cooling systems
The thermostat supports temperature setback control via an external timer.

DEVIreg™ 330 (60 °C to 160 °C)

This version is designed for temperature maintenance systems operating at higher temperatures.
The thermostat supports temperature adjustment from 60 °C to 160 °C and is supplied with a high-temperature silicone sensor.
Typical applications include:
  • Industrial pipe heating
  • High-temperature pipe tracing
  • Process temperature maintenance
