Hello, did you or anyone else figure this out? I’ve added a heat pump and powered it from the controller. The the controller stops heating my heat pump keeps blinking on and off due to no powers. Considering powering the heat pump from a wall socket but then I’ll get a flow error. Gecko control plus relay option would work best if possible or considering adding a small central heating pump powered by the heat pump and controller it via the heat pump schedule. Any help would be greatly appreciated
