ETC1H is a flexible platform due to onboard micro-controller, with enhanced software functionality and up to 3 relays. Perfect for light commercial applications and household applications such as refrigerators, bottle coolers, ice banks, freezers, no-frost freezers with heating element, medicine coolers, and in general any light commercial appliances. • ETC1H can control the cabinet temperature directly. • ETC1H has low energy consumption. • 1 or 2 sensors (Air, evaporator) and optional remote display can be connected. • Using NTC temperature sensors. • Temperature control independent of barometric pressure. • High accuracy combined with close differentials and narrow tolerances ensures improved control. • Built in timers enhances functionality. • Optional alarm for over or under temperature in both cold and warm. • Auxiliary relays: 5 Amp for heater, fan, light etc. Eventually with delayed start or/and stop. • Under voltage and over voltage compressor protection (brown-out protection). • Pressure equalisation protection on starting the device or when voltage drops out (blackout protection). • Diagnostics and self check of sensors and potentiometer. • Several defrosting methods can be handled: Time controlled defrosting, Time controlled defrosting with evaporator sensor, Temperature controlled defrosting. • Dual band control of outdoor bottle coolers.
