3.1.16Temperaturedifferencecontrol

The temperature difference control manages an output according to adjustable temperature differential criteria. The function is independent from all the other functions.

TDiff1 is the temperature of the heating source and TDiff2 of the heating target. Output A3 will be switched on regarding the conditions below, when a timeframe is active.

3.1.17Tubecollector

 

The function “tube collector” can be switched off/on in

 

the “Basic setting” menu – point 4.The timeframe 4 in the

 

“Program” menu makes it possible to activate this function

 

only for a certain period of time (sunshine period).When

 

activated, the solar pump will be switched on every 30

 

minutes for a period of 30 seconds.This is necessary, to

 

measure a temperature change in the collector if there

 

was no circulating for a long period of time.
