EKA NV - Electric duct heaters with built in controls
Electric duct heaters EKA ...NV with built in controls contains temperature regulator which works by algorithm impulse/pause, that enables fine temperature control. Regulator controls load by triacs without moving parts, witch causes no-noise commutation. Potentiometer is used to set temperature. Manual thermal contact restoration button and temperature set point are located on the case of a heater. The duct temperature sensor is needed.
