Charging
Series Static Storage Heater have three models:
∗
manual: 14/69_-3
∗
automatic:
14/69_-4
∗
intelligent: 14/70_-3
- Charging of manual heaters,
Model 14/69_-3
The adjustment of the charge takes place using
the operating knobs on the top right of the heater
(e, fig.29).
The manual Model 14/69_-3 appliances are fitted
with a thermo-mechanical regulator, which moni-
tors the heater charge according to the core tem-
perature. The residual heat left in the core from
the previous day is continuously taken into ac-
count. An additional temperature safety control is
fitted as a separate safety element.
The charge can be adjusted continuously from
zero (control knob fully anticlockwise) to full
charge (control knob fully clockwise “max.“). The
charge control switches off the elements auto-
matically on reaching the set charge.
The “max.“ adjustment should only be used on
the coldest days. The setting best suited to the
ambient conditions is ideally found by trial and er-
ror.
- Charging of automatic heaters,
Model 14/69_-4
The adjustment of the charge takes place using
the operating knobs on the top right of the heater
(e, fig.29).
The automatic Model 14/69_-4 appliances are fit-
ted with a thermo-mechanical regulator, which
monitors the heater charge up to 90% in relation
to the room temperature. The other 10% is influ-
enced by the temperature of the storage core.
The room temperature sensor is mounted inside
the front right of the heater cabinet. The tempera-
ture at this point is in close correlation to the am-
bient temperature.
Two additional temperature safety controls are fit-
ted as separate safety elements.
The charge can be adjusted continuously from
zero (control knob fully anticlockwise) to full
charge (control knob fully clockwise “max.“). The
charge control switches off the elements auto-
matically on reaching the set charge. Setting the
adjustment knob
’e’
in fig. 29 to the end of the
‘comet tail’ will cause the heater only to charge at
temperatures below 5°C (frost protection setting).
The setting best suited to the ambient conditions
can best be found by trial and error. We recom-
mend measuring the room temperature on differ-
ent days at different adjustment settings to find
the best setting suited to the ambient conditions.

Manual reset cut-out
All storage heaters are fitted with a manual reset
cut-out, which will isolate the appliance in the event
of a fault occurring causing the heater to overheat.
This device must be reset by a competent electri-
cian, and the appliance inspected to determine the
reason for operation of the control.
Possible faults:
- Defective charge control regulator B1.
- Appliance has been draped/covered causing heat
stagnation.
