Umwälzpumpe

[Vantive]

Hello!

I have an Vitocal 333-g with Vitotronic 200 control. The system is configured with two heat circuits, one for the basement (under ground =HC1) and one for the rest of the house (=HC2) where we live.

As of now both external circulation pumps stops when outside temperature is "indoor setpoint temperature minus 4 degrees" (21-4=17). This is ok for HC2 but how may I by configuration force the circulation pump for HC1 (basement) to run all year around? I need some heat there to keep the moist away.

I don't want to connect the circulation pump (HC1) with external/separate power since I want to be able to shut down the whole system by unpowering the Vitocal with its power button.

Happy if you could guide me how to configure continuous circulation in one of two heat circuits! Thanks!

Hi Vantive,

the heatpump of circuit one is in a mode called antifreeze. At lower outside
temperatures, it is quite normal that this heatpump is turnig all the time.

Best regards, °ch

Thanks, I'll try to clarify because wasn't an answer to my question 🙂

This is how it is today:
When the spring/summer comes (outside temperature over 17 degrees) my system shuts down both the circulation pumps (Umwälzpumpen) for my two heating circuits HC1 and HC2.

This is how I want it to be:
I want the circulation pump for HC2 to run during the heating season (of course) and during the summer I want the heat circulation in HC2 to stop. My system work like this today. BUT I want the circulation pump for HC1 to run continuously all year around, and not stop during warm season. I don't want the two heat circuits to behave the same.

How may I configure that?
