Single-stage SetPoint Controller Installation & Operation Manual
Choose the placement of the thermostats early in the construction process to enable proper
wiring during rough-in.
Consider the following:
• Install on an interior wall.
• Keep dry. Avoid potential leakage onto the control.
• Ensure relative humidity is less than 90% (non-condensing environment).
• Do not expose to extreme temperatures beyond 32-122°F (0-50°C).
• Do not expose to draft, direct sun, or other cause for inaccurate
temperature readings.
• Install away from equipment, appliances, or other sources of electrical interference.
• Ensure easy access for wiring, viewing, and adjusting the display screen.
• Install approximately 5 feet (1.5m) off the finished floor.
• The maximum length of wire is 500 feet (150m).
• Strip wire to 3⁄8" (10mm) for all terminal connections.
• Use standard, 4-conductor, 18-AWG wire.

Thick Floor Coverings [greater than 3⁄8" (10mm)]
If installing a thick floor covering directly to the subfloor, a groove 1⁄8" (4mm) wide by 1⁄16"
(2mm) deep can be cut into the back of the flooring material to accommodate the wire for
the sensor. Ensure the sensor is located in such a position that the attached wire is able to
reach to a suitable junction location.
Avoid splices under the floor covering to ensure
trouble-free operation. Cut a groove 3⁄16" (5mm)
wide by 3⁄16" (5mm) deep by 13⁄4" (45mm) long to
accommodate the sensor. Locate the sensor midway
between the heating elements to ensure a proper
temperature reading.
Note: If it is not practical to cut a groove in the
surface covering, follow the installation method used
for thin floor coverings.
Floor Sensor Installation
Thin-set or Thin-pour Applications
If installing the floor covering over either a thin-set or thin-pour material of sufficient depth,
the floor sensor can be placed directly into either the thin-set material or the thin-pour
material and covered over. Ensure the sensor is
located in such a position that the attached wire is
able to reach to a suitable junction location. Avoid
splices within the thin set or thin pour to ensure
trouble-free operation. Locate the sensor midway
between the heating elements to ensure a proper
temperature reading.

Tile Floor Coverings
If installing a Floor Sensor (A3040079) into an existing tile floor with sufficiently large grout
lines, the sensor and wire can be installed in one of the grout lines between the tiles. Select
a low-traffic area of the floor that is midway between the heating elements for the sensor
location. Ensure the sensor is located in such a
position that the attached wire is able to
reach to a suitable junction location.
Avoid splices within the grout to ensure trouble-free
operation. Remove the
appropriate grout line and place the sensor and wire
in the floor. Re-grout the area.
Installing the Sensor to the Bottom of a
Subfloor
If installing the sensor to the bottom of a subfloor,
cut a piece of 1" (25mm) thick, rigid insulation into a
6" (150mm) by 6" (150mm) square.
Cut a groove 3⁄16" (5mm) wide by 3⁄16" (5mm)
deep by 13⁄4" (45mm) long into the insulation
to accommodate the sensor. Place the sensor
in the groove and sandwich the sensor
between the insulation and the subfloor.
Use a suitable fastening method to affix the insulation
to the subfloor.

Caution: Do not run sensor wires parallel to telephone or power cables. If the sensor wires
are located in an area with strong sources of electromagnetic interference, use shielded cable
or twisted pair or run the wires in a grounded metal conduit.
The Floor Sensor is supplied with 10' (3m) of cable. If a longer length is required, 24 AWG or
larger wire can be spliced onto the two wires from the sensor. The splices should be properly
soldered and protected in an accessible junction box. Follow the sensor testing instructions
given in this manual and then connect the wires to the control.

Floor Sensor Testing
A good-quality test meter capable of measuring up to 5,000 kΩ (1 kΩ = 1000Ω)
is required to measure the sensor resistance. In addition, measure the actual temperature with
either a good-quality digital thermometer, or if a thermometer
is not available, place a second sensor alongside the one to be tested and compare the
readings.
First, measure the room temperature using the thermometer. Disconnect the Sen and Com
wires from the thermostat. Using an electrical meter, measure the resistance of the Sen and
Com wires at the thermostat location. Using the Temperature vs. Resistance Table below,
estimate the temperature measured by the sensor. The sensor measurement and thermometer
readings should be close. If the test meter reads a very high resistance, there may be a broken
wire, a poor wiring connection or a defective sensor. If the resistance is very low, the wiring
may be shorted, there may be moisture in the sensor or the sensor may be defective. To test
for a defective sensor, measure the resistance directly at the sensor location. Once the test
has been completed, reconnect the Sen and Com wires to the thermostat.
Do not apply voltage to the temperature sensor terminals at any time as damage to the
sensor may result.

Testing the Thermostat Wiring
Testing the Power
------------------------------------------
If the thermostat display turns on, this indicates that the thermostat is operating correctly and
there are no electrical issues. In the event that the display is permanently off:
1. Remove the thermostat front.
2. Use an electrical meter to measure voltage between the R and C wiring terminals. For AC
power supplies, the voltage should measure between 10 to 30 V (ac).
For DC power supplies, the voltage should measure between 10 to 30 V (dc).
3. If the voltage on the R and C wire terminations is continuous and the thermostat display
is not on, the thermostat may have a fault. Contact your Uponor sales representative for
assistance.
If the thermostat display intially powers on but later shuts off intermittently, there may be a
short circuit from the W wire to ground, or the power supply is too small to power the load.
Testing the Heat Zone Output Wiring
----------------------------
1. Touch the
button and set the heating temperature above the current room temperature.
Make sure the display does not flash “Max” if using a floor sensor.
2. When the “Heat On” symbol appears on the display, use an electrical meter
to check for voltage on the W and C wires connected to the zone valve,
wiring center, relay or switching relay. The electrical meter should read
10 to 30 V (ac) or (dc).
3. If the W and C wires have voltage, check the zone valve, wiring center, relay or pump to
determine if the heat device is operating correctly.
