Automatic Operation
The damper may be pre-set to open automatically each day if required. Setting the OUTPUT control at settings other than minimum
results in an automatic boost of heat. A high setting on the output control knob causes the damper to open early afternoon/evening,
conversely a lower setting causes it to open later.
Because the automatic opening of the damper is primarily dependent on core temperature then the amount of charge the heater has
taken has a bearing on the time at which the damper opens. For a given setting of the OUTPUT control, the colder the weather (and
consequentially, the greater the charge taken automatically by the heater) the later the damper will open.
Conversely, for a lower charge input (in milder weather) the earlier the damper will open for a given room temperature boost setting.
The most suitable settings of the Output control for different conditions will be found by experience.
Remember - a high setting of the OUTPUT control early in the day may leave too little heat stored in the heater for the evening, especially
during the less cold weather conditions.
CONVECTOR HEATER OPERATION
Convector Heater - Principle of operation
In addition to the storage heater section the CXLN incorporates a
convector heater element in the front of the heater which may be used
independently of the storage heater, for example to “top up” on very cold
days, or for use in late spring and early autumn when only infrequent
cold spells do not justify continuous use of storage heater. Cool air is
drawn in at the base of the heater, heated by the convector element, and
subsequently emitted from the grille at the top front of the heater.
The convector heater section is intended for use when the output of the
storage heater is not suf
fi
cient to maintain the desired comfort level. For
the most economical operation of the CXLN, the heating system should
normally be designed so that the storage heater section provides the bulk
of the heating requirements, and the convector heater section provides
only top up heat, for example, later in the day in cold weather.
Switching on
To put the convector switch F in the ON position, depress the right-hand side of the switch. The switch neon will glow when the switch
is in the ON position. If the room temperature is below the thermostat setting neon C will glow, showing the convector is providing heat.
Setting the Thermostat
The thermostat knob A should be set to the comfort level required. Turning the knob clockwise will increase the room temperature
selected, but the actual setting to provide the required conditions will be found by experience. If, when the convector heater is switched
ON and available for use, the room temperature is below that set on the control knob, neon C will be illuminated, showing the heater
elements are energised.
