1. Operating Instructions

1.1 Technical Description

Storage heaters store electrically generated heat during low-cost electricity tariff periods
(depending on the electricity supply company, mainly during the night hours). This is then
discharged according to the desired room temperature as hot air by a fan.

1.2 Operation

The heater is operated using the recessable knobs on the top right of the heater. Pressing the knobs
gently inwards causes them to spring outwards, further pressure causes them to recess back into
the heater. The knobs can be recessed in any set position.

1.2.1 Heat storage

Heat storage takes place automatically. The residual heat left over from the previous day is always
taken into account by the charge and discharge control during heater charging.
Automatic charge control
The heater charge adjusting knob should always be set at MAX (fully clockwise). If the charge
should be reduced for any reason, this can be done by turning the knob slightly down. Any changes
made to the settings will only be noticed on the following day. Do not, therefore, make too bigger
changes to the settings.
The heat stored by the complete system is determined by the central charge control (in the
distribution box). Please refer to the operating instructions which come with central charge control
to adjust these settings.
Manual charging
If the heater is not connected to a central charge control, the amount of heat to be stored can be
determined by the infinitely variable charge adjusting knob on the heater itself:
no heat storage:
full heat storage:
Once the set amount of heat has been stored, the heater switches off independently.

1.2.2 Heat discharge

The heat discharge is controlled by the charge and discharge control. If the room temperature sinks
below the set temperature, the heater fan switches on and dissipates warm air into the room until
the set temperature has been reached.
Day-acting element heater switch
This switch switches the day-acting element on and off. If no day-acting element is fitted, the
switch has no function.

1.2.3 Summer operation

In the summer months, the operating knobs for charge and discharge and for the room
temperature should be set to MIN (fully anticlockwise). Do not switch off the central charge
control circuit breaker as this could cause the time clock in the central control to go out of
synchronisation.
