It does not matter about the make, its an excuse why its doing stuff that I want to run past folk. The controller device is wireless, and the folk looking after the boiler are suggesting that the office wifi is causing the problem of it not keeping in touch with the main boiler. Seems a bit of a lame excuse to me. OK its not new, but the landlord seems to me to be making excuses cos it will either cost him too much to fix it, or they really have no idea why its losing its communications and then theboiler reverts to a kind of safe default which is basically frost prevention.
