What do the electricity usage levels in the app tell me?

Created by Themo Support, Modified on Thu, 16 Feb 2023 at 05:31 PM by Themo Support


Underfloor heating and room thermostats are controlled through a relay (on/off) signal. The relay is being activated with a varying duration when heat is requested.


At a high heat request level or high intensity heating, the relay is closed for a longer time than for a low heat request level or low intensity heating



This is data is summarised as Consumption data in the Themo webapp and displayed as graph


Consumption is calculated from how long the relay has been activated and is then multiplied by how much electrical power has been applied to the heating system. 


Themo has built in capabilities to estimate the power level of your direct electrical heating. For hydronic based systems the calculation of power consumption may be inaccurate. If the underfloor heating is behind a separate relay, the automatically calculated power reading may be incorrect (usually 100W). In this case, please make a support request to our customer service.
