Hello, I have a question, how to control the heat pump from the control panel, i.e. I have already connected the control panel to the relay 12V to 230V and it works well, e.g. every 2 hours it starts the pump for 20 minutes, and now I would like to make an emergency switch of the pump e.g. when the control panel is damaged? I understand that I have to use another relay, but I do not know how to draw it, should this emergency switch control 220 current separately, bypassing the relay from the control panel? Regards.
