Can more than one Loose Wire System be controlled by the same thermostat?
Loose Wire Underfloor Heating
Yes, but all heaters being controlled by thermostat must be installed within the same room/ zone. Each thermostat can control up to 16 amps of heating. A maximum of two heaters can be wired directly into the back of the thermostat, if installing more than two heaters connections should be made via a junction box.
