Functional Description
In properties that benefit from a swimming pool,
eddi
can be use to maximise self-consumption of surplus power, by first
heating the domestic water before switching to divert the surplus power to contribute to pool heating.
Heater 1 (the immersion heater in the hot water cylinder) (4) is heated with surplus power until the domestic water is hot
and the thermostat opens, then
eddi
will immediately switch over to Heater 2 to heat the pool (8) with surplus power.
During heating of the pool (Heater 2),
eddi
will briefly switch back to the domestic water heater (Heater 1) every 15 mins to
check if it can store any more heat.
When Heater 2 is active (i.e.
eddi
is heating the pool), Relay 1 of the Relay & Sensor Board (6) will be on and so the pool
circulation pump (11) will run thus transferring heat from the pool heater (9) to the swimming pool.
Installation of the temperature probes (7) is optional; the heaters' mechanical thermostats are used by
eddi
if temperature
readings are not required.
