Hunderliggur said:I drilled a 1/8" hole in the Danfoss plate (per the suggestion of Mark at AHONA) to allow cold return water to always flow in the loop, even just a little bit. Makes the balancing valve work more reliably at the price of a degree or two in the balance. I have not had any problems with the arrangement.
