Thermostat and active heater controller reports

When you use a Thermostat or Active Heater Controller modeling object in a solution, during the solve, the software creates a CSV file that contains the thermostat and active heater controller status at each time step. The file name is: -.ThermostatReport.csv.

The file is written in a simple CSV format:

Time, Thermostat ID/Name, On/Off, Temp Sensor, Power, Numbers ON, Total Time ON, Total Energy Used, P, I, D

Time

Indicates the time step for transient runs.

Thermostat ID/Name

Indicates the name of the Thermostat or Active Heater Controller modeling object.

On/Off

Indicates the status of the thermostat or active heater controller: 1 — it is active; 0 — it is inactive.

Temp Sensor

Indicates the temperature value of the sensor element set.

Power

Indicates the power of the sensor element set.

Numbers ON

Indicates how many times the modeling object was active from the beginning of the run to the current time step.

Total Time ON

Indicates the time in seconds that the thermostat or active heater controller was active from the beginning of the run to the current time step.

Total Energy Used

Indicates how much energy the thermostat or active heater controller used from the beginning of the run to the current time step.

P, I, and D

Indicate the separate power values for the proportional part, P, the integral part, I, and the derivative part, D of the PID controller power. These values are written only for the Active Heater Controller modeling object type of PID Controller.

Example:

Here is a sample thermostat report file.
