I've picked up about half a dozen of these to control my radiator valves.
I'm modulating these with Crestron 0-10V controllers (DIN-4DIM-FLV4). Measuring the controller output these do indeed measure 0-10V exactly when modulating the valves but the valves do not operate.
I'm using the supplied Siemens cable which is wired:
Red - 24V
Grey - 0-10V control
Black - 0V
I've tried running these on 24Vac & DC to no avail. Am I wasting my time with these?
If so can anyone recommend a suitable replacement?
The DIN-4DIM-FLV4 is actually a 4 channel 0-10V lighting controller but totally suitable for this purpose.
Cheers
