Just installed a new boiler system:
Vaillant 637:
Ariston Primo ITI 300:
2x 2 port valves(grey & orange wires isolated):
VR 65:
VRT360.
The CH seems to be working fine but im getting no joy with the DHW. I've swaped the 2 port valves over and still getting the same problem. the d.70 is set to 0. i get the DHW symbol on the boiler so i assume the VRT 360 is working. i've checked the voltage on the vr 65 and only get 240v on the DHW 3 port valve terminal and no voltage on the DHW 2 port valve terminal on the vr 65.
can anyone help?
Thanks
