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.
