How to setup the Danfoss HC10 hydronic controller with Danfoss Link RS_Z
I'm trying to setup a Danfoss HC10 hydronic controller together with 6 Danfoss Link RS-Z and virtual thermostats, but the controller keeps getting into fault mode.
I get the following fault codes, ref. the Danfoss HC10 manual:
Main LED: Red flashing ... Error mode for one or more thermostats.
1-10 Output LEDs: Green flashing ... There is an error in the chain or an indication is required.
If I switch on/off the main power on the Danfoss HC10 it is all cleared and it is operating normally again, but after a while I get the same fault indications again.
Has anyone setup this controller together with virtual thermostats or knows how to do it based on similar systems?
