Dimplex Duo300i, Duo400i, Duo500i Everyday Operation, Non Occupancy vacant, Child Lock Operation

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 fitted 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.
