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

In many families, the weekend looks nothing like the week: sleeping in on Saturday, a shower in the middle of the afternoon, the kids' bath earlier on Sunday. The Stelpro STCP is a programmable floor heating thermostat built for that reality, with 4 periods on weekdays and 4 periods on weekends. Your floor follows your real routine, seven days a week, and does not heat an empty bathroom.

Full programming for your electric floor heating

Who it's for

The STCP is for homeowners who want a warm floor at the right times while keeping an eye on their energy use. It suits bathrooms, kitchens, basements and entryways where electric floor heating has been laid under ceramic tile, stone or another floor covering. It also makes sense in homes where the heated floor works alongside electric baseboard heaters or a wall-mounted heat pump: the floor brings the feeling of comfort, and the rest of the system keeps the house at temperature.

Compatibility and power supply

This thermostat runs on line voltage at 120, 208 or 240 V. It controls a maximum load of 1920 W at 120 V, 3330 W at 208 V or 3840 W at 240 V. It is for electric floor heating only and cannot control a furnace, a central heat pump or a hydronic system. It connects with four wires and has a double-pole (DPST) switch that cuts both poles of the power supply.

Early start

A heated floor takes time to warm up, especially under a concrete slab or thick ceramic tile. The STCP's early start feature begins heating ahead of time so the temperature you want is reached at the time you set. If you program comfort for 6:30 a.m., the floor is warm at 6:30, not half an hour later.

Floor or room air, your choice

The STCP offers advanced control of floor or room air temperature. In floor mode, it relies on the supplied 13 ft (4 m) floor sensor and can be set from 3 to 28 °C (37 to 82 °F). In room mode, it uses its built-in sensor and can be set from 3 to 35 °C (37 to 95 °F). Thermistor sensing gives an accuracy of ±0.5 °C (1 °F), which means steady heat without noticeable swings.

Built-in protection

The thermostat includes a built-in GFCI with a test indicator light, a must-have in a damp room. Safety mode lets you lock in a maximum set point. That is useful to protect a sensitive floor covering or to prevent excessive settings in a rental unit. Power outage protection keeps your settings for 2 hours, so a short outage does not mean reprogramming the unit.

Saving energy in winter

From November to April, an electric heated floor can be in use every day. Programming is the best way to keep its cost under control: comfort when the room is in use, an automatic setback the rest of the time. With four periods available even on weekends, you avoid the usual compromise where the Saturday and Sunday schedule stays too generous for lack of flexibility.

STCP or STCNP

The STCP has a sibling, the STCNP. Both share the same base: line voltage, 13 ft sensor, GFCI, ±0.5 °C accuracy, safety mode and outage protection. The difference is programming. The STCNP only offers a single automatic setback per 24 hours, handy for a night-time reduction. The STCP gives you true multiple programming, with early start, on weekdays and weekends alike. If the room gets used at several points in your day, the STCP is the logical choice.

Installation and setup by our technicians

An installation that gets checked

Our technicians check the floor load and the available voltage, then measure the resistance of the heating elements and the sensor before anything is connected. The thermostat is wired with four wires on a suitable circuit, and the GFCI is tested with you. When we replace a thermostat, we also check the condition of the existing sensor. We then choose the control mode and, if needed, set the maximum set point to suit your floor covering.

A schedule built around you

Setup ends with programming. Together, we set the four weekday periods and the four weekend periods around the times your household gets up, leaves, comes home and goes to bed. You end up with a thermostat that runs on its own.

Maintenance and good habits

Test the GFCI once a month and reset it. Clean the housing with a dry cloth, no liquid cleaners. Keep the space under the thermostat clear so it reads the room air accurately. Review the schedule whenever the season or your family routine changes. That is often where the savings are hiding.
