Mercury is considered to be a hazardous material. If this product is replacing a thermostat that contains
mercury in a sealed tube, contact your local waste management authority for instructions regarding recycling
and proper disposal. It may be unlawful in your state to place it in the trash.
Screwdrivers, wire strippers, wire cutters, and possibly a drill with assorted bits (typically for new
installations only).
This thermostat kit contains a floor/slab temperature sensor that gets wired to the thermostat baseplate. The
floor/slab sensor is an important component in the system, to properly control the heating output commands.
The thermostat uses information from both the on-board internal room/air sensor, and also the wired remote
floor/slab sensor during temperature control. The thermostat controls the room/air temperature to your
desired setpoint value using the heat provided by the floor, but also maintains the floor/slab temperature to
within the MIN/MAX thresholds that you would like it to remain within.
The recommended location in the slab for this sensor is inside of an extra piece of radiant floor tubing at least
3-4 ft. (90-120 cm) in from the perimeter of the slab, with this tube at a depth of approximately 1 in. (25 mm)
below the finished surface of the slab. Please ensure that the sensor is positioned at least 8 in. (20 cm) from
any heated water tubing within the floor/slab, so that the true temperature of the slab is being measured.
1.Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on until all
work is completed.
2.Remove the front portion of your old thermostat to expose the wiring connections.
3.Write down the letters printed near each wire terminal that is used, and also the color
of each wire that is connected to it.
4.Carefully remove the wires one at a time, and bend them in a manner so that they do
not fall back inside the wall. Do not allow bare wire ends to touch each other.
5.Loosen the mounting screws for the old thermostat and carefully remove it from the
wall.
