5. MAINTENANCE
5.1. Maintenance and care
The Lämpöässä ground source heat pump is an easy-care and reliable
heating system that does not require regular maintenance. If the instal-
lation is carried out with care and in accordance with the instructions
provided, there is usually no need for maintenance. The fill container and
mixture circuit filter should be checked every couple of weeks during the
first few months and afterwards approximately once a month for the first
year of use thereafter. Also in pressurized systems it should be checked
regularly that the pressure stays at approx. 1 bar.
Lämpöässä heat pumps which includes 3-6 kg refrigerant are hermati-
cally sealed and therefore annual inspection is not required. You are
offered the possibility of concluding an agreement on periodic inspec-
tions, in connection with which the operation of the Lämpöässä heat
pump is covered stage by stage. The observations are registered in the
inspection record and necessary measures taken (such as adjustments,
for example). For additional information on the periodic inspection agree-
ment, visit huolto@lampoassa.fi.
5.2. Possible problems occurring during use
Problem Possible cause Solution
The compressor
does not start.
The water tank temperature is
adequate and in accordance with the
regulator.
No action re-
quired.
The compressor has been stopped for
less than 1 minutes.
No action re-
quired.
Fuse problem. Check the condi-
tion of the fuses
in the master
switchboard.
Incorrect power supply phase se-
quence.
Contact an electri-
cian.
The compressor
does not start
and the display
reads “Incorrect
phase sequence”
or “Motor protec-
tion switch gone
off”.
Incorrect power supply phase se-
quence.
Contact an electri-
cian.
The motor protection switch has gone
off.
Check the motor
protection switch
adjustment val-
ues, set the motor
protection switch
to Start position
and acknowledge
the alarm text
displayed. If
the fault is not
cleared, contact
an electrician.
The compressor
does not start
and the display
reads “Low pres-
sure switch gone
off” or “High
pressure switch
gone off”.
The low pressure switch has gone off. Check functional-
ity of the brine
circuit pump by
running it through
the mainte-
nance menu and
acknowledge
the alarm text
displayed.
The high pressure switch has gone off. Check func-
tionality of the
condenser pump
by running it
through the main-
tenance menu
and acknowledge
the alarm text
displayed.
The compressor
does not start
and the display
reads “Compres-
sor 1 circuit
1 some motor
protection gone
off. Check motor
protection F1,
F2 or F3.”
The motor protection switch has gone
off.
Press down the
motor protection
switch.
The suction pressure switch on the
pressure switch has gone off.
Set off the switch.
No text is visible
on the display.
The device is not getting any power. Check that that
the control cur-
rent and master
switches are on.
A fuse has blown. Check the build-
ing’s master fuse
and heat pump
supply fuse.
The display is damaged or the display
cable loose or damaged.
Contact mainte-
nance.
The system does
not produce
enough heat.
A sudden drop in outdoor temperature
may temporarily cause inadequate
heating power in new buildings,
because moisture contained in the
structure takes up a lot of heat when
it dries.
No action re-
quired.
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 re-
quired.
In the Measure-
ments 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 correc-
tion function can
be deactivated, if
required.
A spiking over-voltage caused by a
lightning strike has caused a fault in
the regulator (not under warranty),
causing the temperature to drop from
the actual values.
Replace the regu-
lator (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 ad-
justed, the supply water temperature
sensor indicates higher readings as
compared to the adjustment curve, due
to rise in the heat distribution circuit
temperature.
No action re-
quired.
