Cooling - this option is only available for flat plate solar collectors. 

This option makes it possible to cool the tap water heater by switching the solar collector pumps on in a specific time interval starting from 0.00 to the time set in the “

Stop cooling at 

[h]” 

parameter. The cooling option will be active if cooling is on (

Night cooling – Yes

) and the T2 temperature in the heater is higher or equal to the set “

Start cooling”

 temperature. 

Cooling will remain active until the heater gets cooler to the 

“Stop cooling”

 temperature or until the set time interval ends.  

When the collectors are being cooled only the P collector pump operates. All the additional devices connected to the controller are switched off.  

In order to switch cooling on: Press the following key combination: starting point - MAIN SCREEN: enter the

Energy Statistics  

The controller has a built in module for gathering information about collectors` overheating and calculating energy generated by the collectors.  

The following data record is available in the statistics option: 

9.1.

 

Solar overheating

 – information about the occurrence of solar collector overheating (date and time) – the last 50 overheating events can be saved.

 

9.2.

 

Thermal energy

 – collecting and saving data on thermal energy of collectors as daily, weekly, monthly and yearly reports.

 

9.3.

 

Total energy yield

 – displaying total thermal energy computed by the controller.

 

9.4.

 

Reset total energy yield

 – resetting the total energy data (press the OK button twice to reset the counter)

 

9.5.

 

Reset energy statistics

 – resetting the statistics (thermal energy) counter (press the OK button twice to reset the counter)

 

9.6.

 

Anode operation time

 – counting the operating time of titanium anode connected to the controller. After 72 hours (time to stabilise the system) from having connected 

the controller to the mains, the controller will display the date on which it has started counting the anode operating time and saving the anode operating time in days.

 

The controller makes it possible to save and read energy statistics for the following time intervals:

 

- statistics for the last 31 days starting from the date currently set in the controller,  
- monthly statistics for the last 60 months, with possibility of reading the value for a chosen day of the month, 
- yearly statistics for the last 10 years. 

Moreover, for the daily, monthly and yearly statistics there is a possibility of graphical editing of time intervals with the use of bar diagrams.

 

 

When a graphical representation of bar diagrams is being prepared, the largest value presented in a given interval appears in the left upper corner of the screen and the height of 
each bar will be scaled according to this value. Moreover, the right upper corner features date of the recording.
