drayton rf1 thermostat temp reading slow to keep up?

Hi,

How fast should the drayton rf1 thermostat room temp reading keep up?

My new one takes minutes to pick up changes in temp.

for example when i put it in the fridge it takes 5 mins to even start changeing temp.

It's brand new and i've not used it yet, but i'm concerned that it won't work very well come cold weather.

ie it will get very hot or cold before it realises and tells the boiler to shutdown.

is this normal?

No. It should send a signal to the receiver whenever the set-point is crossed, plus every couple of minutes.
Unless they've changed. Call Invensys.

i called them and they said it only updates by 1C every 8 minutes

this seems slow to me, but i guess i'll find out when it gets cold...

that is if it gets cold

They have changed then. Sounds bonkers, will have to think some more.

It might be because of problems with them in halls. Eg someone opens the front door and the heating comes on.

Still sounds too slow though - everyone would think they're faulty!

yep thats what i thought...

the guy on the phone quoted the problem with draughts causing problems, but the time limit of 1c per 8 mins seems excessive to me...

any recommendations on another type?

this is to go with a bosch 30cdi...

Honeywell CM67RF. Miles better. Check the instructions on the H site, which iirc is hard to find.
