Instructions are difficult to interpret and therefore to programme the thermostat, in comparison with previous Danfoss products I have used.
One unit was installed and programmed but there were 2 defects:
1. There was no voltage at channel 2 NO contacts when heat was called for.
2. The Back light on aspect of the program did not work.
Pile of junk I'm afraid. The item was easy to fit and I had high hopes for it but when I put the batteries into the display unit, it took 3 or 4 presses of buttons before the display would react (I checked the batteries were ok, I'm an electrician). Sometimes pressing the touch buttons worked but more often than not it took 3 or 4 presses to get the unit to change temperature or go into the menus which is untenable. Needless to say I'll be returning it ASAP.
Works well, Easy to use, makes it easier to save on heating!
