TROUBLESHOOOTING
WARRANTY
9. TROUBLESHOOTING
9.1 Room temperature varies signicantly from its
setting
• Unit may have been incorrectly sized for the
building.
• Drafts from wrongly placed supply air diffusers or
from the back of the wall plaque could be affecting
the temperature sensor built into the wall plaque.
• Bad air circulation in the room can cause incorrect
temperature readings.
9.2 Air conditioner does not seem to deliver the
heating when most needed
• Heating capacity at design conditions may be
incorrect. As the outside temperature falls, heat
losses through the walls, oor and ceiling increase.
• Check the unit’s brochure for information on the
minimum/ maximum operating temperatures.
9.3 In a new building, why does it take some days
before the air conditioning heat pump unit seems
to work properly
• Many new buildings, especially a commercial
buildings, have a large amount of concrete and other
structural materials that are generally cold and full
of moisture. This is most evident in the winter when
trying to heat the building from scratch.
• Units need need to be checked regularly to ensure
proper operation and that they are not exceeding
operating limits for any length of time.
9.4 HWP unit is spitting or leaking water
• Poor drain trapping (most likely cause).
• Check the drain trap/vent/slope before moving on to
other possible issues.
• Water carry-over: Reduce the maximum fan speed
to the factory default setting.
9.5 Air conditioner runs excessively – the
temperature remains too hot in summer or too cold
in winter.
• Windows or doors may be opened to non-
conditioned areas.
• Keep doors to unconditioned areas (eg laundries,
bathrooms etc.) closed. Note that any doorways
on the return air path will need to be kept open,
which may mean for example that doors to an
unconditioned hallway will need to be kept open.
• Location of wall controller or remote temperature
sensor is wrong.
• Check for leaks in supply or return air ductwork.
