Hi all,

I've purchased the Ideal Logic Air 8 outdoor unit heat pump, along with the Ideal control box and the Elite standard 200l. This is an air to water heat pump for reference.

We have underfloor heating throughout the whole property, and the property has 3 floors so we wanted 3 zones so we can control the temperature on each floor.

Reading the documentation, the recommended thermostat is the Halo Air. However, the maximum zones it can support seems to be 2 from reading the documentation here on Page 40:

ASSETS.CTFASSETS.NET "https://assets.ctfassets.net/sj902orc9wh4/302lPtSPRuwj4lEoGouY6y/abb11291cdddfed6c60389e43fc626b9/IHD_230620_Heat_Pump_Brochure_RevC_Web.pd"

I assume this is down to a limitation on the Halo air smart interface?

If I wanted a 3 zone setup can I buy any thermostat off the shelf like the Heatmiser Neo Air V3. If I purchase this do I need the Heatmiser UH8 to connect to the Ideal control box?

Or can I buy the Halo Air and just select 2 random thermostats like the Neo air V3 and have it all work together.

Sorry if this is a basic question, but I can't seem to get any answers out of the team who are supplying the kit to us, and reading the documentation, it's not massively clear.

Firstly thank you for posting and please be assured no question is 'basic'. People here just want to help.

Please don't buy a third party controller not designed for a heat pump, else you will be back here complaining about poor efficiency.

Heat pumps are generally best run 24*7 with no external controls (unless specifically designed specifically for heat pumps which very few are), in most cases on a single zone. Of course there are exceptions, but they are relatively rare.

The first question I would ask is why do you need 3 zones?

I would strongly suggest you also read this introduction to heat pumps as they have characteristics which are diffent to boilers, and as a result you need to forget almost everything you have been told about how to run heating systems.

If you would like to say a bit more about the house and the heating system I (or someone else) may be able to provide a bit more tailored advice.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
