Function saving electricity by stopping the pump of the regulated
heating circuit when the measured temperature of the circulating
water is maintained for 15 minutes above the preset temperature
water. Recommended setting: 15 min.

Delta T pump
activation
1,5…20
7°C
When difference between solar collector temperature and the
lower DHW temperature exceeds
Delta T pump activation
parameter value, solar pump will be activated.
Delta T pump
deactivation
1…19
3°C
When difference between solar collector temperature and lower
DHW temperature drops below
Delta T pump deactivation
parameter value, solar pump will be deactivated.
Minimum collector
temperature
4…110
10°C
Solar pump will not be enabled below this temperature. If
Minimum collector temperature =
OFF
, function is disabled.
Maximum collector
temperature
110…150
120°C
Above this temperature, solar pump will be enabled in order to
cool the solar panel provided that HUW tank temperature is lower
than the maximum value. If
Maximum collector temperature =
OFF
, function is disabled.
Collector
deactivation
temperature
115…200
150°C
Above this temperature, solar pump will be disabled in order to
prevent it against overheating. Pump will be enabled again after
the solar panel is cooled down. If
Collector deactivation
temperature = OFF
, function is disabled.
Minimal pump

If
Minimum pump rotations
= OFF
, solar pump revolutions
modulation function is disabled (pump always activates with 100%
revolutions).
If
Minimum pump rotations
> 0, solar pump revolutions modulation
function is enabled. Function enables to increase reception of
heat energy from the solar panel at low insolation. Solar pump
decreases its revolutions when difference between temperatures
between a solar collector sensor and DHW tank lower
temperature drops.
Frost protection
mode - solar
-
15…
-35
0°C
Solar panel temperature at which frost protection mode is
activated. This value should be higher than freezing temperature
of the agent inside a solar circuit, e.g. glycol. Solar pump is
activated when solar panel temperature drops below Frost
protection mode - solar parameter value. It causes heat reception
from DHW tank and heating the solar panel. Caution: enabling this
function can cause considerable heat energy losses. When
Frost
protection mode
–
solar = OFF
, frost protection mode of the solar
is disabled.
DHW maximum
temperature
25…90
55°C
Maximum preset temperature of water in the tank. This parameter
defines what temperature the DHW tank will be heated up to
during the solar collector is loaded. It is a very important
parameter because if it is too high, there could be a risk of burning
with utility water. In case of installations with solar system, too low
value will limit heat gains because solar pump loads the DHW tank
to
DHW maximum temperature.
During designing a DHW system,
a possibility of regulator fault should be taken into consideration.
As a result of such failure, water inside the DHW tank can be
heated up to a temperature which is dangerous for users.
Therefore, additional protection should be used in a form of
thermostatic valves.
Night cooling
The controller activates night cooling from 0:00 a.m. to 5:00 a.m.
During this time the regulator will start the collector pump in order
to discharge the DHW tank to the set temperature. Regardless of
the conditions, the controller will exit the cooling mode at 5:00 a.m.
and will go to normal control. Setting
Night cooling
= OFF
disables
the function.
