The Horstman HRT4-Z works fine.
Just wished I could adjust the control parameters of the HRT as I have a water based floor heating under a thick tile floor that takes hours to heat up.
With the I (integrating) element of the HRT4 TPI controller, it means per definition quite some overshoot in the temp response so usually it gets 1 to 2 degrees to warm before the temperature stabilises.
Of course I can accomodate this to by generally increasing the set-point, which is what I do for the time being.
I will probably also calculate the time needed to start the heating based on outside temperature and build a set-point curve on that basis.
But it would be easier to be able to adjust the control parameters in the HRT…
Just wondering if anyone has experience with changing control parameters in a Zwave-stat.
(I can’t find anything on this in the manual and will ask the manufacturer)
