In this menu, you can set 3 time intervals (3 start and 3 stop) for each day
of the week in which the pump will operate according to the set pulse
start. Factory setting: Pulse start pump is active from 08:00 to 17:00
every day of the week. From 17.00 h the first day
until
08.00 h next day
p
ulse start is not operational.

Collector cooling
In this menu, the collector cooling function (over the tank) can be
switched on or off
(tanks must have upper sensor)
.
With this function we
want to delay boiling of the solar fluid in collectors, by raising
the
temperature in the tanks to the maximum temperature [T MAX tank=
90°C].
The collector
cooling function starts
if the temperature in the collectors
reaches [T MAX collector - d
T
Cooling_c
ollecto
r] and if all tanks are full,
to [T MAX tank(set)].
[T

Collector cooling stops if the
coil collector crosses [T MAX collector] or when the temperature drops in
the collectors below

- 2°C]
or when all tanks are filled up to the maximum of [T MAX Tank = 90°C]. If
[T MAX Tank = 90°C] is selected
,
then the maximum
temperature
in the
tank automatically rises to 95°C.
The cooling differential [dTh

collector
.]
can be adjusted
under
PIN
code.
NOTE
:
[T MAX collector] must be adjusted to the point of boiling of solar
fluid in the solar system and must always be lower than the boiling point.

I
n this menu, you can switch the collector freezing function on or off.
Use this function when in the solar water system
is water (instead of
solar fluid)
and if the outer temperatures do not drop below zero. In the
solar system it is always recommended to use a mixture of glycol and
water (solar antifreeze
with
water).

in the collectors rises

Frost protection
starts
from the least priority tank to a tank of higher
priority.
NOTE
:
Only use this function when only water is in the collectors. It is
never recommended to fill the solar system with water only (without
glycol)! By switching on the frost protection function, it is possible to coll
the tanks.
Possible significant energy consumption of conventional
sources in heating tank due to "heating" the collector!
