Performance Troubleshooting
My floor/wall is
getting too hot
My floor/wall
does not get up
to temperature
1. The temperature settings on the thermostat
may be incorrect.
Check the thermostat settings ensuring that it is
controlling the correct surface temperature and
that the set target and limiting temperatures are
correct.
2. The sensor probe may be poorly positioned,
if so the thermostat will be displaying a
temperature that is not indicative of the
surface temperature.
Recalibrate the sensor probe in the thermostat
settings.
3. The thermostat may be set in regulator mode
with the duty cycle set too high.
If the thermostat cannot be set to reference a
sensor probe, reduce the regulation value to
its minimum selectable value. With the heating
active, incrementally increase the setting at an
hourly interval until the required floor surface
temperature is achieved.
1. Underfloor and Wall Heating is normally
designed to heat floors/walls to up to 9 °C
above the design room air temperature, which
is typically 29 °C.
Delicate floor finishes, such as vinyl and some
timbers, may be limited to 27 °C. Our hand and
foot temperature is normally similar to this, at
around 29 - 32 °C, so the heated floor will feel
slightly cooler than touching your own hands
together.
If you wish to raise the temperature, such that it
feels warm, it is permissible to set it up to 15 °C
higher than the design room air temperature.
The higher heat output of the floor/wall may
overheat the room, making it uncomfortable. The
manufacturer of the floor/wall finish should be
consulted to ensure compatibility with the chosen
temperature before making any changes to the
thermostat settings.
2. Refer to points 1, 2 & 3 in the “My floor/wall is
getting too hot” above, as each issue can also
be the cause of under heating a floor or wall.
3. If the thermostat is controlling the heating
using the air temperature, with a sensor probe
temperature limit then the floor/wall may be
turned off before it reaches its limit.
This is normal as the thermostat is preventing the
room air temperature from becoming overheated.
