3 RELAYS DIGITAL THERMOSTAT


The EXPERT NANO MILK is an electronic regulator operating with microprocessor designed for applications of milk preservation / refrigeration; it controls temperature and stirrer. It is fitted with one analogue input for NTC or PTC temperature probe, two digital inputs, three relays for the control of the compressor, stirrer and alarm and buzzer. The regulator can be also configured for heat applications.

Applications • Milk preservation/refrigeration. Main characteristics • Can be configured for hot or cold applications. • Can be configured to read NTC or PTC probes. • Relay for controlling the compressor, stirrer and alarm. • Ability to initiate cycles of temperature reduction, by key or digital input. • Key or DI operated manual START/STOP stirrer. • START/STOP Cyclic stirrer with time settings • Key operated ON/OFF. • Display/adjustment of temperature with decimal point. • Internal buzzer for acoustic signals. • Flat front surface for easy cleaning and keys of ample dimension which can be customized with various colours (on request). • High brightness display with increased icons and figures. • PEGO programming philosophy guaranteeing immediate start-up. • IP65 front protection. Two-fold fastening options: clips / screws. • RS485 serial connection with Modbus-RTU or Telenet protocol.
