Input Control - Dimplex CXLS12N Operating Instructions

CXLSN Storage heater section - Principle of operation
The storage heater section of the CXLSN heater consists of a
core of high density heat storage bricks surrounded by a carefully
designed insulating case. During the night time off-peak period
elements within the brick core heat up the bricks to a temperature
level determined by the setting you select using the input control
knob.
In the morning, when the core is at its hottest, the amount of heat
being transmitted through the insulation and emitted as radiant heat is
at its greatest and the heater feels hot over most of its upper outer
surfaces. Diagram 2.
As the day progresses, heat is transmitted from the heater to the
room and the outer surface of the heater becomes less hot and the
amount of heat released in this way becomes less.
If the amount of emitted heat becomes insufficient the output of the
heater and thus the room temperature may be increased by means of
the Output Control. This control operates a damper flap within the
heater which, when the output control knob is at minimum, covers
vertical airways which pass directly through the centre of the core of
the heater. Even when the outer surfaces of the heater are noticeably
less hot, the core of bricks can still be at a relatively high temperature.
Opening the damper flap by moving the output control away from
minimum allows the room air to circulate through this hot core and
release more heat to the room by convection. Diagram 3.

Input Control

The setting of this control determines the temperature of the room at the end of the charge period, as measured by the heater's
built-in room temperature sensor.
With the Output Control Knob set to minimum (fully anticlockwise) for domestic use, or maximum (fully clockwise) for commercial
applications, the Input Control Knob should initially be set at the mid point position. During the day following the first charge period
the comfort level provided by the heater should be noted. If it is felt that the level of heating is either too high or too low, then the input
control knob should be adjusted up or down as appropriate before the next charge period. This process should be repeated each
day until the most acceptable conditions are attained. The Input Control knob should then be left at this setting, and the heater will
automatically vary the charge taken in during subsequent charge periods to make the most effective use of off-peak electricity to
provide the selected level of comfort at the end of each charge period.
In the Autumn and Spring a lower setting of the input control knob should be sufficient, the actual setting required being influenced
by the prevailing weather conditions, the room size and insulation levels. The most suitable settings will be found by experience.
NOTE - The input charge may be affected by other sources of heat, such as the convector. Please refer to the section '24 Hour
Convector Operation' overleaf.
Output Control
Depending upon the amount of charge accepted by the heater, the OUTPUT control allows the release of additional heat by means
of a damper which can be opened to allow a greater air flow through the heater core, and therefore additional circulation of heat. By
altering the setting of the Output control knob the damper may be opened and closed manually, or it may be made to open
automatically.
