Hi all.
I'm studying the basic works by MHES now. Many thanks and respect for fundamental.
have questions.
What's the logic of using Sommerstop and Sommer Stop difference values? Just ban on ON/OFF?
What's the relationship between SommerStop and VVB?

Hi Shun,

Sommer Stop is the outside temperature where the burner stops if it is above the set.
Sommer Stop Difference is the drop below Sommer Stop which the outside temperature must do before the burner starts again.

Ex.
Sommer Stop = 18
Sommer Stop Difference = 2
Burner will stop when outside temperature is above 18^oC
...and will start again when outside temperature is below 16^oC (18-2 -Sommer Stop - Sommer Stop Difference).

There is no relation between Sommer Stop and VVB  ;)
...they can exist both without influencing each other.

Sommer Stop controls when the burner runs for heating up the house.
VVB is the function to control when the VVB (Warm Water Tank) is heated up, and if the VVB needs to be heated up while the burner is stopped because of Sommer Stop, the burner will start anyway to heat the VVB.

Best regards
Michael

that is to say VVB  has an edge over Sommer Stop, is that correct?

Wel, you could say so, but in reality it is two independent functions  ;)

Summer Stop can start and stop the burner related to the outdoor temperature, VVB can start and stop the burner related to the temperature in the VVB (Warm Water Tank), and the two functions are parallel.
This means that the burner will run if at least one of the two functions demands it and only stop when both functions allow that.

And one more question.
What's the difference between timing settings on Kedel and Program opsætning pages?

[MHES]

Hi Shun,

Please inform me what you are refering to  ;)
...is it StokerKontrol software on the PC ?

exactly.
this picture is from your "handbook".

Hi Shun,

Ok, I understand  ;)

What is written under "Kedel" is done in the control box, and what is written under "Program opsætning" is done in the PC.

This means the timing under "Kedel" works on its own, without a PC connected.
Timing under "Program opsætning" only works when a PC is connected and StokerKontrol is running on the PC.

The timing under "Program opsætning" is realised with serial communication instructions from the PC to the control box, instructions as "Turn ON burner" and "Turn OFF burner", just like if you did it from the keypad on the controlbox.

Michael
