6.3 Consumption
The average consumption of the under oor heating can be read as
a percentage. The thermostat must be on for at least 1 month. To
calculate the average consumption per day, you can use the following
calculation: % x installed power x 24.
Example:
Installed power is 300 watts and consumption is 20%:
20% x 300 watts = 60 watts average consumption per hour.
60W x 24 hours = 1,440 Watts average consumption per day.
