Static Storage Heater intelligent,
Model 14/70_-3
The charge control registers the outside tempera-
ture and converts this value into a control current.
This current is passed via the control wires A1/Z1
and A2/Z2 to the control resistance in each stor-
age heater.
At the same time, the temperature in the heater
core is also registered. The switch-off point of the
charge thermostat is therefore determined by
both the outside temperature and the tempera-
ture of the heater core.
In this way, a control of charge according to the
outside temperature and the residual heat in the
heater is achieved, thus complying with Energy
Saving Legislation.
The control wires can be run together with cable
feeds L, N and PE.

with the Charge Control.

Discharge
(all heaters except Model 14/691)
As already explained in section ‘Operation’, ap-
proximately 80% of the stored heat is dissipated
into the room via convection through the three
channels made for this purpose.
In fig.28 the front channel is shown as
’a’
, the rear
channel as
’b’
and the middle channel as
’c’
. The
air flow through the middle channel
’c’
is controlled
by the flap
’d’
. This flap is adjusted using the left
control element
’f’
on the upper right hand side of
the heater (fig. 29). It is continuously adjustable
from “0“ (fully counter-clockwise) to “max.“ (fully
clockwise).
This discharge control enables the heat dissipation
via the air flow through the middle channel
’c’
to be
regulated by means of naturally boosting or thrott-
ling the convection.
fig.27 shows the flap
’d’
in the closed, fig.28 in the
open position.
Discharge can be classified in two distinct meth-
ods:
- Manual Discharge
In position “0“ (fully counter-clockwise, start of the
comet tail) the flap will not open at all, regardless
of the ambient conditions and the state of the
storage core.
If an increased heat dissipation into the room is
desired, for instance at the start of the evening,
the control mechanism must have a higher set-
ting, so that the flap can open.
- Automatic Discharge
With the control element
’f’
at setting “max.“ (see
fig.29), the air flap opens according to the resid-
ual heat left in the storage core. If the core is still
fully charged the flap remains closed, even if the
control element is set at “max.“.
If the control element is adjusted to a certain set-
ting, the flap opens automatically as soon as the
corresponding level of heat dissipation has been
reached, e.g.:
∗
setting in middle position - the flap opens at
the beginning of the evening
∗
“max.“ setting, the flap opens early afternoon
NB
: Heater
14/691
has no discharge control.
Heat dissipation via convection takes place
only in the front and rear channels (
’a’
and
’b’
in fig.28).

Commissioning
Set charge and discharge adjusters to the “max.“
position and leave them in this position for 48
hours (i.e. 2 charging cycles).
Due to manufacturing techniques, a part of the
heater insulation contains some binding agents
which can cause unpleasant odours during the first
charging. Any dust or machine oils which have col-
lected on the surface of, for instance, the heating
elements will also burn off, causing possible
odours.
It is thus vitally important that the room(s) be well
ventilated during the first 48 hours or 2 charge cy-
cles!
NB:
Model
14/691
has no discharge control ele-
ment.
