Installing the thermostat
If you are using a thermostat with a floor sensor, place the sensor under the Environ™ Flex Rolls, centered between two heat wires, at least 6” (150 mm) into the
heated area.
Make a small divot in the underlayment in this spot and secure the sensor head in the divot with tape. Run the sensor cable in a channel cut into the underlayment
from the heater and back to the thermostat. The “heater wires” within the roll are identified as raised parallel lines. The sensor wire should not cross over the foil heater
wires, and is better placed in a channel cut into the underlayment, under the roll.
