Installing The Thermostat

If you are using a thermostat with a oor 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 identied 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.
