Floor Heating Thermostat STELPRO CONCERTO STF362P | Montreal, Laval, Longueuil, South Shore and North Shore

Programming a heated floor shouldn't take an app, a Wi-Fi password or a touchscreen. The Stelpro CONCERTO STF362P sticks to the essentials: a programmable floor heating thermostat running at line voltage, a large backlit screen that's easy to read even in a dark bathroom first thing in the morning, and buttons that respond without fuss. For a lot of households, it's the best balance of comfort, savings and simplicity in the CONCERTO lineup.

Programming without the hassle

Who it's for

The STF362P suits homeowners with fairly regular schedules: up at the same time every day, a day at work, home in the late afternoon. It's also a good fit for rental buildings and finished basements, where you want a thermostat that's sturdy and easy for occupants to understand. We often install it in family bathrooms, tiled entrances and kitchens where electric floor heating adds to electric baseboard heaters or a wall-mounted heat pump.

Compatible systems

This thermostat is designed for electric floor heating with cables or mats, on a 120, 208 or 240 V supply. It directly controls up to 1800 W at 120 V, 3120 W at 208 V or 3600 W at 240 V (15 A). It doesn't replace the thermostat for a furnace, a central heat pump or a hydronic system. If your floor goes over that load, CONCERTO EXPANSION STF362XU expansion units pick up the extra, and the STF362P stays the only thermostat in the room.

A week programmed in a few minutes

Programming handles up to 4 periods on weekdays and 2 periods on weekends. You set a comfort temperature for when you get up, a setback during the day, comfort again for the evening and a night temperature. On weekends, two periods are usually enough: comfort during the day, setback at night. The adaptive Early Start feature works out when to start so the floor is at the right temperature at the beginning of the programmed period. You don't have to figure out yourself how long the slab takes to warm up.

Saving through the winter

In Quebec, a heated floor can stay on from November to April. With a manual thermostat, people often leave the same setpoint on all the time because they don't think to turn it down. With the STF362P, the setbacks happen on their own when the room is empty. That automatic discipline is the simplest way to cut a heated floor's electricity use without giving up the pleasure of a warm floor when you're actually enjoying it.

Four modes to suit every room

Floor (F) mode works from the floor sensor. Room (R) mode controls the air temperature with the built-in sensor. Room with floor limit (RF) mode heats the air while limiting the floor temperature, which protects engineered wood and vinyl flooring. Controller mode lets it run without a floor sensor. Setting ranges are 5 to 40 °C (41 to 104 °F) for the floor and 0 to 40 °C (32 to 104 °F) for the air, in °C or °F.

Safety and wiring

The STF362P includes a Class A GFCI with a test light, a terminal block and a double-pole (DPST) switch that cuts both poles. The 15 ft (4.5 m) floor sensor is included, and the unit also accepts other manufacturers' sensors: when you're replacing a thermostat, the existing sensor under the floor can often be kept once it's been checked.

Where it fits in the CONCERTO family

The CONCERTO STF362P sits in the middle of the lineup. Compared with the CONCERTO BASIC STF362NP, it adds programming and early start. The CONCERTO TOUCH STF362PTS has those same features plus a colour touchscreen, an installation wizard and an energy use log. The CONCERTO WI-FI STF362WF can be controlled remotely from your phone. If you want reliable programming without a touchscreen or a connection, the STF362P is the most straightforward option.

Professional installation and follow-up

What we do on site

Our technicians start by confirming the floor's load and the voltage at your electrical panel. They measure the resistance of the cables and the sensor, then wire the thermostat in a suitable box on a dedicated circuit. The GFCI is tested, the control mode is chosen based on your flooring, and a floor limit is set if needed. We finish by programming the week with you, around your actual hours.

Getting the most out of it

After installation, give the thermostat a few days to fine-tune its early start. If your work schedule changes, take five minutes to update the periods: that's what keeps the savings coming. If you'll be away for a long time, lower the setpoint instead of shutting off the circuit, so the room doesn't get too cold.

Routine maintenance

Once a month, press the GFCI test button and reset it. Wipe the housing and the screen with a dry cloth. Avoid placing a lamp or a heating appliance right under the thermostat. If the floor stays cold while the screen shows a call for heat, contact us and we'll check the connections and the sensor.

The AirGreen approach

AirGreen Inc. is a family-owned HVAC company that has been based in Montreal for more than 15 years, with an RBQ licence and a showroom in Boucherville. We work on wall-mounted and central heat pumps as much as on electric heating, and we choose the thermostat based on how each room is really used. Our technicians leave a clean job site and a thermostat that's set up and ready.
