Micro-switch 2 activates the temperature limitation as a
maximum temperature limitation.The temperature for the
temperature sensor mounted on clamp S2 is adjusted as a
limiting value at the potentiometer (B). If the adjusted ma-
ximum temperature is exceeded, the relay is switched over
and so prevents e.g. a further storage charge (protection
against overheating). If the maximum store temperature is
exceeded, the operating control lamp flashes red.
The factory setting for the maximum temperature limitation
is activated (micro-switch in ON-position),The temperature
limitation is preadjusted to 60 °C. Adjustable temperature
difference within a range of 20 ... 90 °C.
Micro-switch 3 activates an anti-freeze protection function.
The anti-freeze protection function reacts to the tempe-
rature of sensor S1(e.g. a collector sensor). As soon as
this sensor measures a temperature below +4 °C, warmer
water is pumped from the store to the collector to prevent
damages to the collector; in the course of this the operating
control lamp flashes green. As soon as a temperature of
+5 °C is reached, the pump switches-off again.
Please note: As there is only a limited heat quantity of
the store available for this function, the anti-freeze function
should only be used in regions with few days of temperatures
around freezing point.
The factory setting for the anti-freeze function is deactivated.
(micro-switch in OFF-position).
Micro-switch 4 activates the temperature limitation as a mi-
nimum temperature limitation.The temperature is adjusted
as a limiting value for the sensor mounted on the terminals
S1 at the potentiometer „temperature limitation".The relay
won't switch until the adjusted temperature is reached.This
function should preferably be used in combination with a
solid fuel boiler in order to avoid flue gas condensation
within the boiler. By maintaining a minimum temperature
limitation in the heat generator a flue gas condensation on
the boiler walls is avoided. If the minimum temperature is
underrun, the operating control lamp flashes red.
The factory setting for the minimum temperature limitation
is deactivated (micro-switch in OFF-position).When activa-
ted, a temperature limitation of 60°C is preadjusted.
The LED shows the actual operating status of the cont-
roller.
