re (T0 or T1) was always at constant
optimal level (eg 80ºC)
2. Based on optimal temperature dif-
ference between supply and return.
Speed of the pump is calculated that
dierence of temperature at collector
(T0 or T1) and destination tank (T2
or T5) Was always at constant optimal
level (optimal growth of temperature
for example 20ºC)
To properly determine how speed should
be calculated please ask manufacturer of
collectors. At time of writing this manual,
InsBud vacuum tube collector (classic and
SHCMV) have optimal performance with
method 2 and value of dierence with
20ºC. These values are default settings of
controller.
IController controls of pump speed,
which only has an impact on ow spe-
ed. Therefore rst of all please set opti-
mal ow speed for 80% speed of pump
by suitable balance valve placed just
before pump.
IController has been designed to con-
trol classic pumps currently available
on market. Due to variety of available
pumps we recommend using original
IB-Pump xx-60. By using this pump we
guarantee valid proportional control
of speed. Using other pumps (eg with
dierent strength, dierent type of en-
gine), you must reckon with possibility
that pump will be regulated in steps (not
proportional) or not extent as provided
for in controller algorithm.
Controller allows to adjust minimal speed
of P0 i P1 pump. This means that a suitable
pump will never work with lower speed than
set value. Setting minimal value for 100%
means that pump is only turned on and o
(no speed control).
Minimal speed value of pump is default set
to 10%. This value should be changed only in
two cases:
ePump with minimal speed makes vi-
bration and loud voice in system (very
specic situation for hydraulic installa-
tion). Then gradually increase the mini-
mum speed of the pump until vibration
stops.
eControlled pump is an advanced elec-
tronic pump, dynamically changing its
own speed by its own built-in controller.
In this case, set minimum speed value
to 100% and for safety of pump and its
controller we recommend to connect to
it by separated external relay.

Solar system for whole day heat both tanks
completely (1 and 2). First tank is fresh water
tank. At evening residents of building cool
rst tank (hey used hot water). Normally, at
this point extra heating buster should be
turned on to heat fresh water tank (such as
electric heater – extra heating buster feature
has been previously described in this manu-
al). However, when second tank is still collec-
ted by solar energy, this energy is re-loaded
from second tank to rst fresh water tank (for
example by upper coil exchanger in fresh wa-
ter tank or by external exchanger). This featu-
re allows maximum solar energy use in who-
le system. When re-loading process is active
H1 extra heating buster is turned o.
Control of P3 re-loading pump is in same
way like P0 and P1 pumps, but for calcula-
tion controller using temperatures in the up-
per parts of both tanks (dierence between
T6 and T3).

As you know the speed of uid ow through
the collector is not neutral. If ow speed is too
high, the collector will not be operated with
maximum eciency. If too low, the collector
may fall within the zone of steam.Set of ow
speed at a constant level is only simple so-
lution because this ow speed is optimal for
conditions that were at the time of ow spe-
ed adjustment. If intensity of solar radiation
will change, collector return temperature will
changes automatically also other parameter
will change, after that optimal ow speed (at
which collector has highest eciency and
produces the most energy for current situ-
ation) is very dierent than one previously
set.
Only solution to this problem is automatic
control and ability to change ow speed of
liquid through collector. IB-Tron 4000SOL
controller it is equipped with such a possibi-
lity. Controller controls loading pumps speed
in proportional way so solar collectors are al-
ways working with its highest eciency.
In addition, due to fact that on market there
are many types of solar controllers (and other
equipment working on a similar principle)
calculation of optimal speed can be in two
methods:
1. Based on optimal operating tempe-
rature of collector. Speed of pump
is calculatet that supply temperatu-
