Replacing Drayton LP522 with Hive - straight swap?

[BintyandtheBeast]

Hi everyone,

I’ve removed a Hive system from my house and would like to install in my daughter’s house. Some posts I read tell me it’s a straight swap, others tell me it’s a bit more involved. Can anyone point me in correct direction please?

Our house:
Underfloor heating with Heatmiser wiring unit which would turn on our heating when calling for demand irrespective of what Hive was doing. No way to control via Hive
Upstairs & hot water (stored in Megaflo cylinder) were controlled by Hive

My daughter’s house:
Single zone heating throughout
Megaflo cylinder for hot water
No separate room stat anywhere - radiators have TRVs (except in 2 bathrooms which left the loop open) and system would be simple on or off from Drayton programmer.

Can I just take off the Drayton programmer and attach the Hive unit on same backplate?

Many thanks for your help

Yes, that should be fine to swap out without issue.

Thanks CountryFan. Can confirm it was a straight swap!

You want heating? I am trying to find better way to cool my house.

Interests me nevertheless, I know my Drayton Wiser does not need a wall thermostat, it can use the TRV head to control if the boiler runs, but did not realise the older system could use the TRV heads to control boiler.

What am I missing?

They don't, the OP didn't say they did.

With no thermostat the boiler is either on or off, nothing else.
