2 RELAYS DIGITAL THERMOSTAT


The Expert NANO 2ZN is an electronic thermoregulator with two relays for hot/cold or humidifies/dehumidifies in neutral zone. It can be used also for a double setpoint with two separated outputs. It has one analogue input for NTC temperature probe, one analog input for humidity probe, two relays with separate contacts and RS485 output for monitoring system (TeleNet or Modbus-RTU). Buzzer is included and the power supply depending on model.

Applications • Management of climatic storage rooms. Main characteristics • Configurable for hot/cold call or humidifies/dehumidifies call in neutral zone or as double set-point with distinct outputs. • Key operated ON/OFF. • Display/adjustment of temperature with decimal point. • Flat front surface for easy cleaning and keys of ample dimension which can be customized with various colours (on request). • Internal buzzer for acoustic signals. • High brightness display with increased icons and figures. • PEGO programming philosophy guaranteeing immediate start-up. • RS485 serial connection with Modbus-RTU or Telenet protocol. • IP65 front protection. Two-fold fastening options: clips / screws.
