That's waterfall vs. agile development. A small incremental feature addition could make a big change to the product, but it needs to wait till the next major release.

I've just received the Nu-heat design, which shows manifold ports 1-6 for zone 1 and ports 7-8 for zone 2. Each zone is going to be controlled with a T87RF2033 single zone thermostat. Just noticed in the HCC80R spec that it is limited to 3 thermal actuators per zone. Any suggestions how I can get around the limitation and still end up with only 2 zones for WUFH?

i would suggest halving this into 2 zones with a wireless room sensor at either end of the areaI work for Resideo, posts are personal and my own views.

It's an open plan kitchen area (9m x 9m) plus a loop into the utility room. I'd rather avoid multiple zones as I'm nearly maxed on on zones for the evohome controller due to HR92's. Could the 6 actuators be wired into some kind of junction box then into the HCC80R? Seems an odd limitation as other wiring centres must support more than 3 actuators per zone.

There is nothing stopping you from wiring up the actuators to all 5 zones (or all 8 using the HCS80 expansion card) and then register each to the same Evo Touch zone andnroom sensor. So you could use all connectors from Zones 1-3 on your HCC80R for your 6-loop zone, then Zones 4&5 for you other 2 loops. That way you don't need to cram more than one actuator flex into each connector (although getting two cables into each terminal is not too difficult either).Sensible Heat

using an external junction box is fine, but if you've got enough spare/unused outputs on the HCC80R then you have the option to use them too and save the need for the junction box.
In most cases it is also possible with care to feed two thermal actuator cables into one cable entry and connect them into the same terminal on the HCC80R zone output. If the thermal actuator cables get shortens then you also need to replace the ferrules to avoid any stray strands from the cables poking out, but it would be good practice to do his anyway when terminating stranded cables.Sensible Heat
