100% GEOTHERMAL HEAT

MAINTENANCE MANUAL

Use the button in the bottom left corner to return to the home screen. Use the arrow button in the bottom right corner to return to previous screen.

For instructions screen, press the ‘i’ button in the top right corner. In case of operation faults, an alarm button is displayed on the top bar.

The system does
not produce enough
heat.

A sudden drop in outdoor
temperature may temporari

ly cause inadequate heating
power in new buildings,
because moisture contained
in the structure takes up a
lot of heat when it dries.

No action required.

During the first year, the
ground circuit may not
produce heat at full power
because the earth around
the ground circuit pipes has
not yet become more solid.

No action required.

In the Measurements
screen, the set value
and measured value
do not match.

Some active correction
function (for example, timer
or home/away) is adjusting
the original set value.

The active correction func

tion can be deactivated, if
required.

A spiking over-voltage caus

ed by a lightning strike has
caused a fault in the regu

lator (not under warranty),
causing the temperature to
drop from the actual values.

Replace the regulator (not
under warranty).

The regulator motor has
been set on manual and
the regulation does not take
place.

Return the heat distribution
circuit adjustment motor to
automatic mode.

In summer, when the
building indoor temperature
exceeds the value adjusted,
the supply water tempera

ture sensor indicates higher
readings as compared to the
adjustment curve, due to
rise in the heat distribution
circuit temperature.

No action required.

The compressor is
on all the time or for
long periods of time.

A lot of heat is needed, for
example the outdoor tem

perature is very low or the
structure is drying during
the first year’s use of the
building.

No action required.

Lack of refrigerant. Can be
detected from bubbles in
the liquid container even
after some minutes of use.

lier or maintenance
