As title really. If you had to recommend one, which is it?

I use Honeywell but find the connections a wee bit small.

I probably use them through habit and I only use them when I'm not installing a Vaillant.

What are you lot using ?
 
Honeywell or centre brand. They seems to lose a few minutes each month though

I find Honeywell (CM927) to be the best of fairly a weak field. Their time keeping spec is pretty poor to start with (10 mins/year IIRC) and they seem to be significantly worse than this in practice. I think this is a design flaw as pairs seem to stay in sync nicely they just both tell the same wrong time. They have a long history of LCD displays failng prematurely. I keep hoping the ones currently being sold won't suffer from but I'm probably deluding myself.

I like the fact that, with some jumping through hoops, one can synchronise multizone duty-cycles with them but they have a minimum ZV call that is too short (30s) and can't be increased.

Why do I use with them? Inertia/laziness probably. They're the devil I know, they are fairly easy to programme and the TP control works well and keeps the temperature rock steady.
 
I also use the cm927 fitted dozens of them with very few faults but they are now being phased out with a new range from honeywell the T4 i believe cheers kop.

We recently installed delta dore tybox which seemed to me not bad product to be honest.
