Note: 

It will take 24 hours for room temperature to reach a comfortable level when resetting 
from  “Setback”, “Frost Protect”, “Off” to “Comfort”.

Everyday Operation

Once the Background level has been set (see Achieving Optimum 
Comfort Level above), this should not require any further 
adjustment.
Adjust the Comfort setting as required to suit your comfort needs 
and occupancy pattern.  For a short period of non occupancy the 
control can be lowered slightly (we recommend by no more than 2 
bars) to save energy when the room is unoccupied and increased 
again when more heat is needed.

Non Occupancy (vacant)

For long periods of non occupancy, reduce the 

Background 

 and 

the 

Comfort

 to their lowest settings.

It will take 24 hours for room temperature to reach a 
comfortable level when resetting from Low settings to Normal 
settings.

Child Lock Operation

To activate the child lock simultaneously depress the 

+

 

and 

-

 

buttons for a period of 3 seconds.  After this period the child 

lock is in operation and the LED will illuminate for short period and 
then revert to the setback setting.  The LED beside the key symbol 
will illuminate while the child lock is in operation.

Once in the locked position, if either of the controls are operated 
the LED will resume maximum illumination for a short period before 
reverting back to the setback position.

To deactivate the child lock, depress the buttons simultaneously 
again for 3 seconds and the buttons will become active.

Safety - Overheat Protection

For your safety, this appliance is 

fi

 tted with thermal cut-outs.  In the 

event that the product overheats, the cut-outs switch the radiator 
off automatically.  In the event of these safety cut-outs activating 
please inform the installer or Dimplex Customer Services for advice 
in order to reset the cut-outs.
