C35-FC

18. Trouble shooting guide

Symptom

Diagnostic Test 

Cause

Solution

Home screen temperature 
reading is incorrect.

Confi rm room temperature 
using a thermometer.

The device has not had 
enough time to power up 
and stabilise.

After resetting the device, 
wait 30 minutes prior to 
adjusting parameters. 

The device has not been 
calibrated.

Calculate and input the 
temperature offsets. See 
chapter 

12.4. Offset.

Unit has not been mounted 
correctly, resulting 
in uncharacteristic 
temperatures.

Remount device in a suitable 
mounting location and follow 
mounting instructions. See 
chapter 

4. Mounting diagram.

Incompatible remote sensor 
has been connected.

Only use the PT1000 resistive 
temperature sensor.

The device is not mounted 
properly.

Ensure the device has clicked 
into place on the wall mount. 
See chapter 

5. Mounting 

instructions.

Relative humidity reading 
is incorrect.

Compare measurements 
against a reference  
instrument.

The device has not had 
enough time to power up 
and stabilise.

Read chapter 

First start up 

and Commissioning.

The device has not been 
calibrated.

Calculate and input the offsets. 
See chapter 

12.4. Offsets.

Display is not ON or the 
device appears to be OFF.

Touch the screen: the device 
should awaken upon contact. 
If not:

The connecting pins have 
been damaged during 
installation.

Ensure none of the connector 
pins are bent. If required, 
gently realign any bent pins.

The device is not mounted 
correctly.

Ensure the device has clicked 
into place on the wall mount. 
See chapter 

5. Mounting 

instructions.

The device’s wiring has not 
been installed correctly.

Install the device in line with 
the wiring diagrams. See 
chapter 

14. Applications and 

connection diagrams.

Display’s touch screen is not 
responding to touch or it is 
responding incorrectly.

Touch the screen to see if 
there is a response.

A pressure has already been 
applied on touchscreen 
surface.

Check the perimeter of the 
display and remove any dust 
or dirt.

Check if plastic enclosure 
is applying pressure on 
touchscreen due to incorrect 
mounting. Check if wall mount 
is mounted on uneven surface.

If the pressure has been 
applied at one place but 
the graphic response 
is on other part of the 
screen, recalibration of the 
touchscreen is required. 

For recalibration of touch 
screen, please see chapter 
21. Calibration of Resistive 
Touchscreen.
