How do I calculate my Sinopé thermostat’s power needs?

To choose a Sinopé thermostat, add up the wattage of every heating device it will control (baseboards, convectors, etc.), then pick a model whose maximum load is equal to or greater than that total. The wattage is shown on each device’s label; for a 240 V baseboard, you can also estimate it at 250 W per foot. Sinopé line-voltage triac thermostats have a built-in safety margin: a 3,000 W thermostat can safely control a total load of 3,000 W.

Can I connect several heating devices to one Sinopé thermostat?Peut-on brancher plusieurs appareils de chauffage sur un seul thermostat Sinopé?

Yes. A Sinopé thermostat can control several baseboard heaters or convectors, as long as their combined wattage does not exceed its maximum load. This is common in open areas, such as a kitchen, living room or dining room on the same thermostat. Start by identifying every heating device connected to that thermostat.

How do I calculate the total power of my heating devices?Comment calculer la puissance totale de mes appareils de chauffage?

The wattage of a baseboard heater or convector is usually printed on the manufacturer’s label attached to the device.

If the label is unreadable, estimate it with this rule, valid only for a 240 V installation: wattage (W) = 250 W × baseboard length (in feet). For example, a 6-foot baseboard draws 6 × 250 W = 1,500 W.

⚠️ This rule does not apply to 120 V installations.Cette règle ne s’applique pas aux installations à 120 V.

Electric baseboard heater wattage by length (240 V)
Baseboard length Wattage at 240 V
2 ft 500 W
3 ft 750 W
4 ft 1000 W
5 ft 1250 W
6 ft 1500 W
8 ft 2000 W
10 ft 2500 W

How do I choose the right wattage of Sinopé thermostat?

Add up the wattage of every heating device on the thermostat, then choose a Sinopé thermostat whose maximum load is equal to or greater than that total. For example, two 6-foot baseboards (2 × 1,500 W = 3,000 W) need a thermostat rated for at least 3,000 W.

Can a Sinopé thermostat run at 100% of its maximum load?

Yes. Sinopé line-voltage triac thermostats are designed with a built-in safety margin and can safely handle their rated maximum load. A 3,000 W thermostat is therefore suitable for a total load of 3,000 W, and a 4,000 W thermostat for a 4,000 W load.
