Electric Heat EHS 20 Pro. There are 2 spring loaded terminals for connecting the thermostat wiring.
Connect one wire to each terminal. If the Power Electric Heat EHS 20 Pro is placed inside the space to
be heated, place the thermostat on top of the unit. For applications where the Power Electric Heat EHS
20 Pro is placed outside the space to be heated (e.g. ducting heat into a chamber), the 25’ cord allows
you to place the thermostat inside the heated space.
In addition to the included thermostat, any dry-contact switch or other type of control that connects the
terminals together will cause the heating elements to run. The thermostat circuit is low voltage (24VAC).
