What evohome configuration to choose?

[alexandruvisan89]

Hi,

I would like to install an evohome system for 5 zone in my house.
My home has the following configuration:

- have 2 floors
First floor:

Zone 1: 3 radiators (dinning and kitchen)
Zone 2: 4/5 radiators (this is the leaving zone + stairs)

Second floor:

Zone 3: 3 radiators (bedroom)
Zone 4: 2 radiators (bedroom)
Zone 5: 1 radiator (office)

Other than above radiators a have 3 bathroom, each with 1 radiator. 1 for leaving room, and 2 for each bedroom.

My heating system is a ferroli gas central without boiler.
Also, my radiators are connected to 2 distribution center for each floor, which i can't physically connect them by wire.

From what i know:

I can choose to control the zones using hr91/hr92 radiators controllers, but will be a mess due the fact i must use 14/17 controllers.

Or I can choose to use 2 hcc80 controllers for each floor distributor.

My questions are:

1. Which system do you think suits me well?
2. I tend to buy the system with 2 hcc80 controllers, which a presume is engineered for heat floor system. Is any problem if I use it for radiators?
3. It is possible to connect 2 hcc80 to 1 ATP921?

Thank you,
Alex

So the HCC80 is now discontinued, its now the HCC100 (https://thesmartthermostatshop.co.uk/pr ... c100m2022/).

You can use more than one HCC100 with 1x ATP921R3100.

Either way will work, but HR91/92's will give you more accurate temp control over the HCC100 UFH controller with radiators in my opinion.
