The EHT-2-220 can switch an additional Load of up to 8A (resistive)
between terminals 4 and 5 if this contact is not used for unit state indication
or PLC feedback. The diagram 8.2 shows a dehumidifying application
using a fan heater with a 230VAC heating element and a DC powered
Fan. e.g.:
DBK Typhoon Series Fan heaters.
