S2.1 Protection - cooling of
solar system
When the temperature in the storage tank is higher than
the set point temperature, heating with the collectors stops.
If then the collector temperature exceeds maximum tempe-
rature Tmax, the solar pump switches on again until collec-
tors are cooled down to the value of hysteresis P1.18.
In case the storage tank exceeds the maximum temperatu-
re, the solar pump stops unconditionally.
0 - OFF
1 - ON

S2.2 Impulsive pump mode -
tube collectors
Special algorithm activates the solar pump to switch -on for
short intervals. This way you get realistic temperature of
collectors. This function is used especially with vacuum
(tube) collectors. This function is also possible with classic
collectors if the sensor is fitted outside of the collector
body.
0 - no
1 - yes
0
S2.3 Collector’s frost
protection
If the temperature drops bellow the set point value (P2.18),
the solar pump switches -on to prevent freezing in the
collectors and pipelines.
NOTE: This setting is suitable only for climates areas
where the temperature only occasionally drops bellow the
freezing point.
0 - OFF
1 - ON

S2.4 Order of storage tank
priorities
In a system with two or more storage tanks, you set the
order of loading priority.
1 - seq. 1, 2.
2 - seq. ..2,1
1
S2.5 Storage tank priority -
operation interval
If the system is loading (for a setted time) the non priority
storage tank, the operation is temporarily stopped. This
way controller (after setted pause interval S2.6) again
loads the priority storage tank.
5 ÷ 60 min
20
S2.6
Storage tank priority -
pause interval
This is the time in which controller waits for rise of collector
temperature, which needs to be 2 K or higher. If the rise is
sufficient, controller waits for the differential condition for
loading the priority storage tank to be fulfilled. If temperatu-
re rise isn't sufficient, the controller starts to load first non-
priority storage tank with fulfilled differential condition.

S2.7 Reverse cooling
of storage tank 1
Means that storage tank 1, if heated above the set-point
temperature, can be forcibly cooled down to the set-point
temperature. Cooling is achieved by means of collectors
and pipe installation.
0 - no
1 - yes
0
S2.8 Reverse cooling
of storage tank 2
Means that storage tank 2, if heated above the set-point
temperature, can be forcibly cooled down to the set-point
temperature. Cooling is achieved by means of collectors
and pipe installation.
0 - no
1 - yes
0
S2.9 Reverse cooling
of storage tank 3
Means that storage tank 3, if heated above the set-point
temperature, can be forcibly cooled down to the set-point
temperature. Cooling is achieved by means of collectors
and pipe installation.
