We proud to announce our new produc, developed with our Russian partner "Smartmatica" 


Multifunction hygrothermostat with three control ports SMART-0903.

Multi-functional hygrothermostat with three control ports is developed to control temperature and humidity inenclosures of various applications.
The control is performed by turning on / off the heater, fan or air conditioner connected to it according to the received information from the built-in or optionally connected external temperature sensor. The device can operate in two modes:
- ”Mode 1” the device supplies power to the equipment when the temperature and humidity are set by the settings.
- “Mode 2” the device provides energy efficiency by turning on the fan for cooling, and in case of insufficient efficiency it turns off the fan and turns on a more powerful cooling device (air conditioner or other cooling device).

To prevent corrosion processes and to protect against excessive humidity, the device provides an increase in the dew point at a critical excess of relative humidity (above 65%), and thereby prevents appearance of condensate.
