UponorA heat-only thermostat built for hot-water radiant floors. Two wires at 24 V, a touchscreen, and three control modes: air, floor or both, with an optional slab sensor.
Uponor’s wiring diagram shows what happens when a room cools down. Pick your setup and how far the room is below setpoint, then step through it.
Per Uponor: CDAM design manual, 8th edition (CDAM_1023), wiring schematics 1 and 2 (p. 145 and 146), and the A3100101 manual (0221) for the call and modulation. These are Uponor’s diagrams with Uponor parts; another module, relay or boiler is checked case by case on quotation.
Uponor’s manual offers three modes. The floor covering sets the surface temperature not to exceed. Answer three questions.
Uponor: a surface of 80 °F (26.7 °C) at most for hardwood, and generally 87.5 °F (30.8 °C) at most for other finished floors. Also check your flooring manufacturer’s limit.
AirGreen × Uponor
Uponor designs the thermostat, the control chain and the rules that go with them. AirGreen starts from your module and your floor to tell you whether the A3100101 fits, on quotation.
The result: a thermostat picked for your module and your floor covering, price on quotation.
We sell the thermostat. The manual also names the Uponor parts that go with it in a zone; they are not in our shop.
Heat-only touchscreen thermostat for hydronic radiant floors.
Parts named in the A3100101 manual; A9010599, A3031003 and A3031004 shown as “Active” on Uponor’s Canadian site on Oct. 20, 2026.
Taken from Uponor’s manual and submittal. They help you avoid ordering a thermostat that does not fit the system in place.
The A3100101 is a 24 V thermostat for hydronic radiant heating. Uponor’s documents mention no electric floor.
With an Uponor A3031003 or A3031004 module, Rh and W go to terminals 2 and 3. With another relay, the 10 kΩ resistor may be needed.
Output of 1.3 A at 24 VAC, which is about six actuators per thermostat according to the manual.
Interior wall, about 5 ft (1.5 m) above the floor, away from heat sources and drafts.
We sell the thermostat and advise you on the mode, the sensor and the parts, based on Uponor’s documents.
A partner holding RBQ subclass 15.4 does the hydronic work. The manual reserves installation for professionals familiar with low-voltage wiring.
What Uponor Ltd.’s limited warranty and the programs themselves say.
For installations made after May 12, 2026 (document 051226).
No Uponor on the list of certified smart thermostats.
The grant targets a Wi-Fi thermostat on its ENERGY STAR list: the A3100101 is not on it.
LogisVert has no thermostat measure.
Its floor thermostat is for electric floors, not water-based systems.
No. The A3100101 is a 24 V thermostat for hydronic radiant floors, wired to a zone module, a relay or a valve. Uponor’s documents mention no electric floor. For an electric floor, see our other thermostats.
No. It runs on two wires with power sharing, on terminals Rh (R) and W, with no polarity. It has no batteries. The floor sensor wires separately, to SEN1 and COM.
No. Uponor’s submittal calls it non-programmable: you set the temperature and it holds it. The manual has no schedule.
No. No wireless connection and no app.
No. The A9010599 slab sensor (10k) is sold separately. Its 10 ft lead extends up to 250 ft in 18 AWG. Without it, only the air mode is possible.
Uponor’s design manual sets 80 °F (26.7 °C) at most at the surface for hardwood, and generally 87.5 °F (30.8 °C) for other finished floors. With the slab sensor, the A3100101 applies a maximum floor limit adjustable up to 35 °C (95 °F).
The manual allows other makers’ relays, valves or boilers, sometimes with the included 10 kΩ resistor. Each setup is checked on quotation.
The output is 1.3 A at 24 VAC, which is about six actuators according to Uponor’s manual.
In Uponor’s diagram, the module waits until the actuator or valve is open: the end switch closes, then the ES-ES contact powers the pump relay.
Per the manual, the thermostat falls back to an 18 °C (65 °F) air setpoint. In Off mode, freeze protection holds 3 °C (37 °F).
Uponor Ltd.’s, for installations made after May 12, 2026. Thermostats are not named in it, so we show no term. It requires a contractor recognized by Uponor and excludes labour.
None among the programs checked as of October 20, 2026. It is not ENERGY STAR listed, it is not on Énergir’s list, LogisVert does not cover thermostats and Hilo is for electric floors.
