HouseControl E+ Installation Manual
Connect the device to the EXT relay. You can
use the relay, for example, for controlling
magnetic valve in water pipe and prevent water
damages.
Important: Make sure that max load 230VAC/6A is not exceeded under any circumstances.
Important: When relay is used to steer inductive load (for example, another contactor), connect
RC filter or EMC suppression component in parallel to load to stop voltage spikes when
contactor releases. Voltage spike may break the relay.

2. Connect the battery.
3. Attach the battery to the casing with two-
