1 RELAY DIGITAL THERMOSTAT


The EXPERT NANO 1LT is a 1 relay electronic thermoregulator designed to control static refrigeration units operating at normal temperature with off-cycle defrosting (to stop compressor). It is fitted with one analogic input for NTC or PTC temperature probes and one relay for the control of the compressor. The regulator can be also configured for heat or alarm application.

Applications • Control of refrigerated counters, display windows and refrigeration units. Main characteristics • Can be configured for hot or cold or alarm applications. • Off-cycle defrosting can be set on the basis of frequency or duration. • Key operated manual START/STOP defrosting. • 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). • High brightness display with increased icons and figures. • PEGO programming philosophy guaranteeing immediate start-up. • IP65 front protection. Two-fold fastening options: clips / screws. • Relay capacity and power depending on model.
