So far I found Uponor C-55 to be the only zone controller that works with wireless thermostats. Is anyone aware of any other products? I'm retrofitting radiant floor heat (staple-up) but need a controller for the actuators that works with wireless thermostats for the different zones. Thanks, Tim

I can't find any controller on that side. Are you sure they have anything for radiant floor application? So a controller where the actuators and pump are connected?

Many wireless thermostats interface to whatever you are controlling the same as any other thermostat. So you can connect them to whatever system you would have used otherwise same as a wired thermostat.

Are you using zone valves or multiple circulator pumps? Do you have a particular thermostat in mind?

I'll be using 8x zone valves and 2 pumps

Here's a basic wiring diagram for zone valves. You can do it just as shown, except that each "thermostat" gets replaced by the receiver half of whatever wireless thermostat you choose, and the wires that say "to aquastat" actually go to a circulator control relay, like a taco SR502

I recommend taco "sentry" zone valves, by the way, because they consume much less power than any alternative I've found. And an ECM pump like grundfos Alpha or Taco Viridian VT2218

thanks!
