   Confirmation key or navigation key in the menu (OK).
   N.B .: on the main screen it is possible to choose the sensor that must always be displayed; press the (OK) key to display the desired sensor.
   Installation menu.
   Press the (OK) key for 5 seconds to access the installation menu.
   When accessing the installation menu (the first parameter “Syst” is displayed), it is possible to choose another parameter by pressing the navigation key (OK). Once the desired parameter is displayed, it is possible to change the value with the (►+) or (-◄) keys.
   Lock function.
   To avoid errors after installation, all critical parameters (system and Extra function) are not accessible after more than 4 hours have passed from start up. If you want to change them, you will need to disconnect and reconnect the control unit. No settings are lost during disconnection or after an electrical blackout.
   Key:
   After 4 hours, all other settings can be changed to optimize the A Control unit; system.

System choice.
“SySt” parameter (Default value “1” cannot be modified). System 1. Base system, with 1 tank, 1 pump, series of manifolds, and 2 sensors. It can be enriched with extra functions with 1 or 2 sensors T3 (NTC) or T4 (PT1000) (Thermostat, Cooling, Anti-stagnation or diff Control function).

Tank 1 charging is possible if the temperature difference “dt” between the collector (T1) and tank 1 (T2) is sufficient. Choice of the manifold. “TubE” parameter (Default value “off “). Once the “TubE” parameter has been selected, press the navigation key to the right (+) to choose the type of manifold installed.

• At this point select “on” if your system uses a vacuum pipe manifold. (This function can also be used with a flat manifold if the sensor is mounted on the outer parts of the manifold). This function works as follows. Every 30 minutes the pump runs for 40 seconds to measure the correct value on the manifold and avoid a cycle with short charge.

• Select “off ” if the system works with a flat manifold under normal conditions of use.
  Manifold maximum temperature.
  “ColM” parameter (Default value “120”).

• Set the level to start the overheating protection for the manifold (Adjustable from 110 to 150°C, with factory setting at 120°C). Overheating protection. “OvrH” parameter (Default value “On”). This function will stop the circulations of all manifolds (P1 and P2) when the manifold temperature increases above “ColM” plus a compensation value (default value +10°C, modifiable). This function is used to protect the system elements (pipes, fittings, ring seals ..).

• To activate the function press (►+) selecting “on”.

• The compensation level can now be adjusted.
  “Ovrt” parameter (Default value “20°C”).
  This compensation is generally used to avoid a too fast reaction of the overheating protection function (especially useful with the vacuum pipe manifold). (Adjustable from +10°C to +30°C with factory value +10°C).
  N.B .: for safety reasons, the overheating protection must always be “on”.
  Cooling.
  “Cool” parameter (Default value “On”). This option is used to protect the manifold liquid and works as described below. It activates the solar pump P1 or P2 if the temperature on the series 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 water temperature in the tank reaches 90°C). “Rcoo” parameter (Default value “On”).
  When the water temperature in the tank exceeds the “Maxtemp tank1” setting level and the manifold temperature has dropped by 10°C, the pump is activated to cool the tank through manifolds. The pump will turn off when the water temperature drops to the “tkM1” setting level or when the difference between the temperature of the series of manifolds and the tank is less than 2°C.
  Anti-freeze protection. “FrEZ” parameter (Default value “off “). This option keeps the temperature of the solar panel T1 or T4 above the level set for frost with the “Frzt” parameter by activating pump P1 or P2. This option can be used to reduce the accumulation of snow on the panel and increase efficiency during the day or avoid damage to the solar liquid.
  N.B .: it is preferable not to use this function in areas that are too cold to avoid using too much energy stored in the tank.

• To activate the function, press (+) and select “on”.

• The Freeze setting level can now be adjusted.
  “FrZt” parameter (default value “10°C” (Adjustable from -20°C to + 7°C with recommended value 3°C).
  Display.
  “Disp” parameter (Default value “OFF”).
  Backlight function.

• To disable or disable the backlight function, press (+) or (-).

• If it is “Off” the backlight will turn off automatically 3 minutes after pressing the button.

• If it is “On” the backlight will always be active.
  Factory setting.
  “Fact” parameter.

• If you want to reload all the parameters with the factory values, hold down the (+) key for a few seconds.
  N.B.: for reasons of protection from errors and security reasons, the chosen system will not be reset.
  Setting menu (setting) In this menu you have all the adjustable parameters for your system. The various parameters are not available on all systems.
  To access the Setting menu, press the (-◄) and (►+) keys simultaneously. Once you have entered the Installation menu (the first parameter
  “TkM1” is displayed), it is possible to choose another parameter by pressing the navigation key (OK). Once the desired parameter is displayed, it is possible to change the value with the (►+) or (-◄) keys.

• The maximum temperature on tank 1.
  “TkM1” parameter (Default value “65°C”).

• The maximum value of the desired water temperature on tank 1 during normal operation (Adjustable from 15 to 95°C with factory value 65°C).

• Maximum delta temperature for tank 1
  “dtM1” parameter (Default value “15°C”).

• Difference between the temperature T1 of the manifold and the temperature T2 of the tank 1 to activate the main pump 1 (Adjustable from 3 to 40°C with a recommended value of 7°C).

• Minimum delta temperature for tank 1.
  “dtm1” parameter (Default value “7°C”).

• Difference between the temperature T1 of the manifold and the temperature T2 of the tank 1 to stop the main pump 1 (Adjustable from 2 to (dTMax tank1

• 2°C) with a recommended value of 3°C).

• Minimum temperature on the manifold.
  “mtCo” parameter (Default value “25°C”).

• This setting level is used to define a minimum temperature on the manifold to authorize solar charging (Adjustable between 0°C and 99°C with default value 25°C).

CIRCULATION PUMP (THERMAL SOLAR SYSTEM COMBINATION KIT).
The units are supplied with pumps equipped with a speed regulator. These settings are adequate for most plant solutions. The pump is equipped with electronic control that allows you to set advanced functions. For correct operation, it is necessary to choose the type of operation most suitable for the system and select the speed in the available range, favouring energy savings.

Operating status display (Fig. 12). When starting the circulating pump, the LED (2) lights up green for about 2 seconds, then it starts flashing for a short time at higher intensity and finally it switches off during normal operation. The LED (3) switches on only during PWM setting, not usable in the application. The three yellow LEDs (4) indicate the three constant curve speeds.
