MAIN FEATURES

Mini-sized and integrated intelligent controller, with very simple end-user interface: Change of set point is made without password, with up and down keys.

Input Humidity: capacitive sensor

Input  temperature:

NTC : value R@25°C:10KO (±1%), B@25/50°C: 3380KQ (±1%)
Pt100 and thermocouple K Inputs: standard curves

Output relays: 16A 250V res. and (or) 10A 250V res. depending on models.

Output relay action for temperature : customer set to open on temperature rise or close on temperature rise

Alarm: 5A alarm relay on thermocouple K models

Temperature differential (if T° option exists): adjustable by customers, from  1 to 10 °C

Output relay action for humidity: customer set to open by humidity rise or close by humidity rise

Temperature display:  -45°C  to +120° ±1°C or 0.3% FE ± one digit. Customer setting of display in °C or °F.

Humidity display: 1-99% (+/-5%)

Humidity adjustment range: 20 to 99%

Humidity differential adjustment range: 1 to 70%

Other settings: start delay time and offset

Power supply: AC 220-230V 50-60Hz

Technical informations associated to this product

  • Electrical contacts

    As numerous mechanisms exist, we decided not to distinguish on the basis of constructive technique, but according to their operation speed, which is the key element.
  • Temperature sensing principles

    The bimetal strip is formed by two co-laminated metal. One has a high coefficient of expansion, the othera lower or zero. When the strip is heated, it bends proportionally to the temperature. These bimetal blades are generally flat and fixed at one end. But they can be wound in a spiral shape, although this arrangement most often used in the construction of thermometers.
  • Terminology and vocabulary used for thermostats

    Standards EN60730 and EN 60335 define, sometimes with differences, the vocabulary to use. However, it is often different from that used in practice.
