underfloor heating room thermostat

[One_of_them]

Hey

I've an issue with a rehau thermostat that is used for an underfloor heating system. This goes to a distribution controller and then to actuators x8 (however it seems to only actually run 2 of them) to allow the flow for the heated water
anyways my question is are underfloor thermo's any different form normal ones? Its mains 3-wired and i keep seeing ones that are "suplied with batteries" and "2-wired"

just feeling a bit muddled

cheers

is there a stat for each actuator mate?normally 1 actuator for each room/zone controlled by its own stat.cant really see how 1 stat will work properly if controlling 8 zones .everytime i`ve done them its 1 stat for 1 zone for 1 actuator.simples.....

Hey.

It's 1 thermostat controlling 2 actuators which is how its wired at the distribution control unit. The other 6 actuators are not been used by the look of it even though it is the only room with the UFH so all seems a waste.
