Electronic hygrothermwith LCD screen
● Electronic temperature and humidity controller.
● Input voltages: 9-30 V, 110-127 V and 220-240 V.
● Hygrotherm with 2 independent switching relays (ventilation / heating function).
● Thermostat precision: +/–1.5 °C.
● Hygrostat precision: +/–5% RH, relative humidity.
● Option of installing external PTC sensors, ref.
NSYCCAST
, for remote reading
(L = 3 m).
● PC plastic material, self-extinguishing according to standard UL94 V0.
● Option of displaying the temperature in degrees Celsius °C or Fahrenheit °F.

*Comparison mode in relay 2: an external sensor is required for the comparison function (Text - Tint).
Example of mode 3: Decides whether the external temperature is favourable and controls the
ventilation (Relay 1) or heating (Relay 2).
Advantage of mode 3: Energy efficiency. Option of efficiently heating the enclosure by ventilation
(using hot external air) before bringing the resistance heater into operation. The thermostat
automatically detects any connected sensors.
