-====== Data for HVAC analytics ======
-==== General information ====
-Building operation is (or at least shall be) determined by a schedule. Therefore we need some information about regimes in the building (at least non-stop operation vs. office hours determined operation). This applies to all analytical topics listed below.
-We do not require outdoor temperature, we use independent data source.
-Bellow is a list of recommend variables for each analytical topic.
-==== Heating circuit ====
-^ Signal ^ Type ^ Note ^
-| Supply water temperature | measurement and setpoint |  |
-| Return water temperature | measurement |  |
-| Pump | measurement or setpoint | |
-| Valve | setpoint | |
-==== Energy meter ====
-^ Signal ^ Type ^ Note ^
-| Cumulative meter value | measurement | "Energy" measurement is more valuable than "power" for the analysis |
-==== Indoor air quality ====
-^ Signal ^ Type ^ Note ^
-| Indoor temperature | measurement and setpoint | |
-==== Air handling unit ====
-AHU is more complex appliance and there is no unified data set for analysis. Usually, AHU is described by 15 - 30 relevant variables.
-^ Signal ^ Type ^ Note ^
-| fans | measurement or setpoint |fan state, frequency converter data |
-| heating | measurement or setpoint | supply and return temperatures, pump and valve |
-| cooling | measurement or setpoint | supply and return temperatures, pump and valve |
-| humidifier | measurement or setpoint | |
-| heat recovery | measurement or setpoint | bypass position, wheel speed |
-| air temperatures | measurement and setpoint | supply, zone, outlet |
-| dampers | measurement or setpoint |  |
