7.3 (a) The Blueberry controller has two different setting
programs, Standard and Eco mode generation.
(b) Standard Mode: The Blueberry controller will raise the
temperature to 130°F (or the programmed temperature)
and then switch off. It will automatically start again
to raise the water temperature once it falls to 120°F.
(or 10°F lower than programmed temperature).
(c) To view the set point temperature, press the P button.
SP is displayed alternatively with the set temperature.
Using the buttons with the arrow pointing upwards
/ downwards we can increase / reduce the set point
temperature. Once set, press the “P” button or leave and
the program will revert to displaying the actual water
  temperature.Thisisdisplayedingures14&15
(d) The temperature range is from 50 to 130ºF. The unit will
raise the temperature to 130°F (or the programmed
temperature) and then switch off. It will automatically start
to raise the water temperature once it falls to 130°F. (or
10°F lower than programmed temperature).
(e) Standard Mode also incorporates an Anti-legionella
cycle, this is is actuated automatically, once a
week (every Monday between 5:00 to 7:00) using
the integral real-time clock within the blueberry
controller.
(f) During the Antilegionalla mode the controller will
automatically heat water within the cylinder to 140°F as an
anti-legionella measure. It uses the heat pump not the
immersion heater to heat the water to this temperature.
7.4 (a) Eco mode is activated when the Blueberry controller receives
  asignalfromtheinstalled2conductorwire(refertosection6)
that the connected PV inverter is generating electricity.
(b) When Eco mode is active, The Blueberry controller displays
the temperature of the water at any time but will
  intermittentlyash‘Eco’acrossthecontrollerscreen.
(c) When in Eco mode the Blueberry controller will raise the
temperature to 140°F and then switch off. It will automatically
start again to raise the water temperature once it falls to 130°F.
(d) When the Blueberry controller stops receiving a signal
from the installed 2 conductor wire that the connected
PV inverter is generating electricity, the Blueberry Controller
will exit Eco Mode and enter standard Mode.
