Controls Overview
The user controls consist of an LCD display, programme selection buttons, option buttons; start reset
button and a stand-by button.
The control system consists of a control module, 2 thermistors and a conductivity sensor.
The conductivity sensor is mounted in the front air duct. A single wire connects the sensor to the
control module. The thermistors and conductivity sensor sends values back to the control module.
The control module then determines the programme duration and dryness of the load in a set values
for a particular programme held within the control module software.
The control module is located behind the right hand side panel and there is a service port behind the
plinth cover that allows attachment of a computer to programme the EEPROM.
The control module can be programmed with the relevant eeprom file if the module is replaced, the
eeprom file becomes corrupted or if an updated file becomes available.
Once the programme has started an estimate is made within 10 minutes of the programme starting
to determine the moisture content in the load and therefore the required time to complete the
programme. This is achieved by use of the front thermistor, rear thermistor and conductivity sensor.
The display will then count down from the estimated time.
Note: -
During the first 3 minutes of this Auto Sensing period the heater and pump are off.
If the display reaches 10 minutes and the signal from the sensor has not reached the required value,
the display will remain at 10 minutes until the required dryness level is obtained.
If, after the maximum programme time of 240 minutes, the clothes are still not dry, the programme
advances to cool tumble and completes the programme. No fault is indicated if this occurs.
The module also controls the heater. This has an upper and lower element. The lower (static)
element is permanently energised (except in cool tumble) and the upper element (dynamic) is cycled
on and off by the control module during a programme to maintain the correct temperature within the
drum for the programme selected.
If the user turns off the power or disconnects the mains cable or there is a power cut, the dryer will
remember its last settings and resume the programme when the start button is pressed.
The start of a programme can be delayed up to a maximum of 24 hours programmed in 1 hour steps.
The maximum delay time available depends on the model.
Crease Care
If the Delay Option is set, when Crease Care is enabled the drum will tumble the clothes for 3
seconds every 30 minutes for the duration of the delay period to minimise creasing.
When Crease Care is enabled, when the Programme has finished the Drum will tumble for 3 seconds
every 4 minutes up to a maximum of 10 hours to prevent the clothes from creasing.
In the event of a controls or thermistor failure, a one-shot cut-out thermostat is fitted as a safety
device.
