Block function.
To prevent errors after installation, all the critical parameters
(system and Extra function) cannot be accessed when over 4 hours
have elapsed after start-up. If you wish to edit them, disconnect
and reconnect the control unit. No settings are lost during dis-
connection or after a blackout.
After 4 hours it is possible to change all the other settings to
optimise the system.
System selection.
"SySt" parameter (Default value "1" not editable).
System 1.
Base system with 1 tank, 1 pump / circulator, 1 series of manifolds
and 2 sensors. It can be enriched by extra functions with 1 or 2 T3
(NTC) or T4 (PT1000) sensors (Thermostat, Cooling, Anti-stag-
nation or Diff control function).
T1
P1
Tank 1 can be loaded if the temperature difference "dt" between
manifold (T1) and tank 1 (T2) is sufficient.
Manifold selection.
"TubE" parameter (Default value "off ").
After selecting the "TubE" parameter, press the navigation key to
the right (▶+) to select the type of manifold installed.
- Now select "on" if your system uses a manifold with vacuum
pipes. (This function can also be used with a flat manifold if the
sensor is mounted on the outside of the manifold). This function
works as follows. Every 30 minutes the pump is activated for
40 seconds to measure the correct value on the manifold and
prevent a short charging cycle.
- Select "off " if the system works with a flat manifold in normal
operating conditions.
Maximum manifold temperature.
"ColM" parameter (default value "120").
- Set the level to start the overheating protection for the manifold.
(Adjustable between 110 and 150°C, with default value 120°C)
Overheating protection.
"OvrH" parameter (default value "on").
This function will stop the circulation of all the manifolds (P1 and
P2) when the temperature of the manifold increases above "ColM"
plus a compensation value (default value +10°C, modifiable). This
function is used to protect the system elements (pipes, fittings,
ring-shaped rubber gaskets).
- To activate the function, press (▶+) selecting "on".
- Now you can adjust the compensation level.
"Ovrt" parameter (default value "20°C").
T2
This compensation is normally used to prevent an excessively
fast reaction of the overheating protection function (particularly
useful with vacuum pipe manifolds).
(Adjustable between +10°C and +30°C with default value +10°C).
N.B.: For safety reasons, the overheating protection function must
always be set at ("on").
Cooling.
"Cool" parameter (default value "On").
This option is used to protect the manifold liquid and operates as
described below. Activate solar pump P1 or P2 if the temperature
of the set of manifolds T1 or T4 exceeds the "Max temp" value,
even if the maximum temperature set in the tank is exceeded.
Circulation stops when the temperature has dropped by 10°C.
(The pumps stop if the temperature of the water in the tank
reaches 90°C).
"Rcoo" parameter (default value "On").
When the temperature of the water in the tank exceeds the level
set in "Maxtemp tank1" and the temperature of the manifold has
gone down by 10°C, the pump starts-up to cool down the tank
via the manifolds. The pump will switch off when the tempera-
ture of the water drops below the level set in "tkM1" or when the
difference between the temperature of the set of manifolds and
of the tank is below 2°C.
Antifreeze protection.
"FrEZ" parameter (default value "off ")
27
This option maintains the temperature of solar panel T1 or T4
above the level set for freezing with the "Frzt" parameter, acti-
vating pump P1 or P2.
This option can be used to reduce the build-up of snow on the
panel and to increase the efficiency during the day or prevent
damage to the solar liquid.
N.B.: it is preferable not to use this function in very cold places to
prevent using too much energy accumulated in the tank.
- To activate the function, press (▶+) and select "on".
- Now you can adjust the Freezing setting.
"FrZt" parameter (default value "10°C" (Adjustable between -20°C
and + 7°C with recommended value 3°C).
Display.
"DiSP" parameter (default value "OFF").
Back-lighting function.
- To enable or disable the back-lighting function press (▶+) or
(-◀).
- If it is "Off" the back-lighting will switch off automatically 3
minutes after having pressed the key.
- If it is "On" the back-lighting will always be active.
Factory setting.
"Fact" parameter.
- If you want to reload all the parameters with factory settings,
press and hold the (▶+) key for a few seconds.
N.B.: For safety and error prevention purposes, the system selected
will not be reset.
