WOW! i know this thread is old, but theres some pretty F***cking arrogant know-it-all's on here. I'm also a tenant, (sorry about being a pondlife non home-owning family in good full time jobs, but thats life), and had this system installed just 9 months ago by the council. Now, this panel is tucked away in our airing cupboard, and strangely enough, this warm weather means i dont have a reason to think i need to inspect the display every week, but i have also noticed this message on my system. I'm pretty well clued up on DIY and technical/mechanical subjects as my inferior above average wage job requires it, but even i didn't know about this service issue. You all claim that you highly privileged and intelligent homeowners with huge debts over your heads, have no need for this reminder as you're all obviously much more intelligent than the average person. But lets not forget that tenants, or should i say the oh so smart property owning landlords, have a duty to schedule annual services of heating, electrical and gas systems. Therefore, the tenant is going to be less likely to need the reminder as super intelligent responsible landlords should be maintaining their property anyway with checks carried out before the last one expires.
Secondly, as for not knowing what this message means, i was not told about it by the very clever engineer, and nor was it mentioned anywhere in the literature that i was given. Sadly, us clueless tenants didn't have the same luxury of being born with all the same information as you natural born engineering homeowners.
Unfortunately, when we don't know something, we have to come onto these demoralising forums to admit our shameful lack of engineering degrees and being a tenant, and be abused by clever people in the hope of learning our lesson.
So like Wemyssie, i have also learnt my valuable life lessons.... 1) homeowners are obviously very clever people, albeit arrogant, self absorbed ****s whose neck is being squeezed very tightly by their own arseholes
and 2) Distrust landlords when thinking they might actually conform to rules and regulations, by carrying out routine safety checks at the required intervals
and 3) this message means it needs a service
