Temperature readings appear to measure too high
Check the placement of your CM7 Sensors. If the sensor is receiving any direct sunlight
during the day, this will heat up the case of the sensor. As this heat is retained, it will also
affect the temperature being measured and lift it above the true value.
Make sure that the sensor is not subject to direct sunlight – or other nearby sources of
heat – as this is the best way achieve accurate readings.
Another possible cause of temperature measurements over-reading is the type of
batteries being used. Certain batteries can heat up slightly when in use, so this could
potentially cause the temperature sensor to measure slightly higher than usual. Use
good quality lithium batteries (and avoid rechargeable varieties) in order to minimise
the effects of this.
If your outdoor sensor is producing a reading that is extremely high (and not realistically
possible) it could be due to some moisture within the outdoor sensor. Bring this part
inside, remove the batteries and leave it in an area with low humidity (such as an
airing cupboard) for 48 hours to allow it to dry out. When you re-insert the batteries,
temperature and humidity readings should be correct. Remember to use the Sensor
Search Mode detailed on Page 17 to quickly re-establish this connection with the
console.
Indoor and remote temperature readings do not match when placed in the same
location
The differing shapes and sizes of these parts can cause them to warm and cool at slightly
different rates. In normal usage, if the two parts are placed side-by-side in the same
environment and given time to settle, measurements should match very closely. The
error margin for each part is +/– 1°C, so in practice this difference could be up to 2°C.
Temperature readings can be calibrated manually if this is preferable – please refer to
Page 31 if this would be required.
