Hive HAH2PMZ Active Heating Multi zone, Thermostat Only, No Installation, Black, 10.0 cm*10.0 cm*10.0 cm

my old controller worked on a 2 degree difference ie you set for 21 it wouldn't kick in till it was 19 degrees and switch off at 23. This you had a min of 4 degrees difference . this is approx. !/2 to 1 degree difference and keeps the temperature stable. With the hive app you can control this away from home . A friend uses this for his parents that have dementia . He can ensure that the house stays warm even if they turn the system down. You can get notifications if the temp drops or rises above a set temp. excellent piece of equipment. My only complaint is it needs a stand unless lying flat.

Delighted with our Hive setup, we bought it without installation (as we are in Ireland) and also bought a Multi Zone kit as we were doing a full heating system upgrade. Once installed and setup to work with the remote valves in the house we now have our 3 zones of Downstairs / Upstairs & Hot Water, paired with a new condensing oil boiler and new hot water tank our efficency has increased dramaticly. Its fantastic being able to turn on the hot water for a shower before coming home from a jog or making sure the heating is warming the house up on the way home from work. Even the freeze protection should there ever be a big freeze is great. The app is simple but effective but could do with some tweaks to the interface like being able to swipe across to the zones instead of having to go back every time, maybe a widget on iOS would be great too. Its a shame the thermo's screens are off all the time, I would like to be able to at least see current temperature on the stats at all times but this is a minor gripe. All in all we're quite happy with the setup and it came is cheaper then the competing nest option while still looking pretty slick.

I purchased the 'Multizone Additional Smart Thermostat' as a replacement for my original thermostat. I was therefore a little surprised to see this supplied with a new single channel (heating only) receiver. You do not need this if you are buying this as a replacement for an existing thermostat. The new thermostat was relatively easy to reset and pair with my existing dual channel (heating and water) receiver, but the Hive App showed the thermostat and water as being offline, despite everything working correctly internally - everything had green lights, I could manually adjust the temperature and turn the heating on etc. After several resets this problem persisted so I called Hive. They were extremely helpful, and were able to delete the old thermostat from my account, which immediately made everything work as expected. Pity you can't delete the old thermostat yourself, but full credit to Hive customer service for sorting this in a phone call lasting less than 1 minute! Recommended.

Product was as described, no problems. Installed hundreds of these next to no problems. Would buy again!

Do not buy !!! I had done my research....looked at other systems...and felt I'd made a good choice in selecting hive. Ordered it in the Nov sales but only fitted on 9th Jan when we got our new boiler. ...and then the problems began. When it's working, it's exactly what I wanted. Easy to schedule (takes seconds), easy to link to alexa, easy to boost & update. Great !! But 1. The whole system goes offline - every day. Requiring factory reset of everything and an hour on the phone to hive customer service (who are lovely btw). The signal booster I was sent goes offline...then everything else follows it. I have 3 heating zones & 3 light bulbs- quite an investment. 2. The multizone system that was meant for my wet underfloor system isn't compatible. In fact a few other wet systems I've looked into aren't compatible either. Which are hive?? 3. As I bought it for my plumber to fit when he fitted my boiler...and it wasn't connected by British gas...there's no hive warranty or engineer support...even though we've had issues with it since getting it out of the box. Fuming ?... Yes. Disappointed...yes. A 2nd signal booster should arrive this week - if it doesn't work to make the system more reliable, the whole thing will have to be taken out and sent back. So further time, expense and hassle on top of the 10 days I've had it so far.

Had connectivity issues at the beginning. Customer support were going around in circles and tried to blame me as I did self install. Worked in the end and work well now! 4 star because of the day and a half of the stress.

Easy to install if you are comfortable with mains multizone boiler wiring. If the phrases "motorised valve" and "boiler interlock" are foreign to you, you might need to get a qualified installer, or at least google the terms and see if it all makes sense to you. Adding the new zone to my existing account was straightforward using the mobile app. Have been using 2 zones plus hot water for a few weeks now without any issues. It all just works. Packaging and instructions are very good. Overall no complaints, though would have liked if it were a little less expensive :-)

It includes the wall mounted part where all the wiring is done and the control interface. Both are working fine for more than 2 months after installation. The sad piece is that backplate for the control unit is not included and must be purchased separately. Neither this can be seen on the pictures nor it is provided in the description. Moreover, the 3rd piece the hub to connect thermostat to the internet is another piece you need to buy separately.
