Hi,
After quite some research I decided to upgrade from my ancient switchmaster 805 programmer after having a new Vaillant ecotech plus 415 boiler installed a couple of years ago. So I've gone down the Vaillant route with the following:
VR65 Control Center
VR392 Room Programmer
I've kept my switchmaster cylinder thermostat and connected up these items as per the 3 port valve installation guide that came with the VR65. I've used just the brown and blue cable of the old thermostat in the VR65 CYL electrical ports. Everything powers up fine the programmer works great and the central heating settings seem to work as they should, but the hot water isnt running right. So i want to check that i've not got something wrong?
The VR392 programmer instructions state to remove the red jumper link in ports 3&4 of the boiler if external 230v controls are to be fitted? I understood this to mean any additional third party programmer controls, but does this mean the old cylinder thermostat control? So by removing this jumper i'm assuming the VR65 would then supply power to the CYL electrical ports and the thermostat would start working correctly?
At first I thought I may have had the polarity on the cylinder thermostat around the wrong way as it seemed that when I turned the thermostat down to 20degrees celsius the boiler turned on, and when i turned it up to 70degrees celsius the boiler went off? Changing the polarity over made no difference.
The only way I can seem to get the water working is by turning up the water temperature on the boiler from 15 to the next value up 40. But then the cylinder thermostat clicks at near on 80 degrees and the water is squalding when it comes out of the taps.
What do other people have their water flow temperature set to on the programmers too? Although I'm pretty sure this is unmeasured unless I connected up the VR10 sensor that came with the VR65. If I was to connect this up along with the exisitng cylinder thermostat, how would I wire these two up in the VR65?
Any help ad advice is much appreciated
