(a)
The controller has two different setting programs, Standard
and Eco mode generation.
(b)
Standard Mode: The 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

(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 05:00 to 07:00) using
the integral real-time clock within the 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.

(a)
Eco mode is activated when the controller receives a signal

When in Eco mode the 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 controller stops receiving a signal from the
installed 2 conductor wire that the connected PV inverter is
generating electricity, the Controller will exit Eco Mode and
