Priority
The priority for heater outputs can be set to Heater 1 or Heater 2. The priority heater will be heated first with
the surplus power and only when fully heated will
eddi
start to divert power to the lower priority heater.
eddi
will switch back to the priority heater if it has cooled and the thermostat for the heater is closed.
When heating the lower priority heater, the Check Period sets how often the priority heater is checked to see
if it can store any more heat.
If the Relay & Sensor Board is installed and temperature probes are used,
eddi
will immediately switch back
to the priority heater if the temperature drops by more than the set Hysteresis. The Hysteresis can be set in
the Temperatures menu of the Relays & Sensors menu option.
12.2.2 Hot Cancel Delay
If you would like to have a delay between switching from your priority heater to your lower priority heater there
is a setting called Hot Cancel Delay where you can choose how long the delay should be from 0 to 61 minutes.
To use this function go to Heater Settings > Boost > Select the duration of delay you require and press (
) to
confirm.

Advanced Settings
The Advanced Settings menu is passcode protected.
The default passcode is
0 0 0 0
although it can be changed with the Passcode menu option.

Supply Grid – Device Settings
13.1.1
Supply Grid – Phase
The phase setting is only used when installing the
eddi
in a 3-phase property.
It should be set to match the phase number that the
eddi
is wired to so that the power measurements are
correct and that the
eddi
responds to the correct phase when using the
harvi
wireless sensor. See Three-
Phase Systems and Net Phases for more information.
13.1.2
Supply Grid – Device Limit
Sets the maximum current that the
eddi
will draw (including when boosting). This is useful if the supply current
is limited, like a 13A fused spur rather than a 16A MCB.
13.1.3
Supply Grid – Grid Limit
Sets the limit that can be drawn from the grid connection (i.e. the maximum import current or the main fuse
rating). Grid Limit is a global limit; all the
myenergi
networked devices will be included when limiting.
Example:
A property has a grid supply limit of 65A, several appliances are on and the property is consuming
12kW (52A) by other appliances and the user wants to boost the water heating. If the water heater is rated at
3kW (13A), the total consumption would exceed the allowed import current. However, with a Grid Limit setting
of 60A,
eddi
would limit the power to the heater to 1.8kW (8A) and therefore the maximum allowed import
current would not be exceeded.
