Maximising your energy savings
To increase the efficiency of the central heating
system, your heat pump will automatically vary
the temperature of the water going through
your central heating. The colder the temperature
gets outside, the warmer the circulating water
through your central heating.
This feature (called weather compensation or
economy mode) should be selected on the
controller, and the
show in the controller display. If this symbol is
not shown, press the

When in the automatic (weather compensation)
mode, if you feel the house is too warm or
not warm enough you can adjust the central
heating water supply temperature up or down
by pressing the
buttons on the controller.
