We have a new Vaillant ecoTEC 624 boiler (installed in November), operating as a system boiler. It wasn't getting on well with our Honeywell thermostat, so we decided to get the vSmart thermostat and VR66 wiring control centre, which should work better with it.
One thing that seems to be missing from the installation instructions is the settings we need on the boiler once the VR66 and vSmart are up and running.
Should we set the boiler to the default settings or something specific? Or are the boiler's internal settings simply overridden by the VR66? It would be really useful to know.
Thanks!
