 ## Overview
 
-Refer to the [Commissioning Scripts](https://github.com/automatic-controls/commissioning-scripts) add-on for WebCTRL. This script is intended to evaluate performance of control programs which optionally include a supply fan, damper, and heating element. Evaluating more than one of each component in a single control program is not yet supported. For example, this script should not be used to evaluate a program which controls two heat pumps at once.

 Supply fan evaluation requires a binary output to command the fan and a binary input to monitor status. Damper evaluation requires an airflow microblock in the control program (works with controllers [ZN141A](https://www.automatedlogic.com/en/products/webctrl-building-automation-system/building-controllers/zn141a/), [ZN341A](https://www.automatedlogic.com/en/products/webctrl-building-automation-system/building-controllers/zn341a/), [OF141-E2](https://www.automatedlogic.com/en/products/webctrl-building-automation-system/building-controllers/OF141-E2/), and [OF342-E2](https://www.automatedlogic.com/en/products/webctrl-building-automation-system/building-controllers/OF342-E2/)). There are two heating configurations which can be evaluated. The first configuration requires a single analog output to vary heating output between 0 and 100 (e.g, hot water valves and SCR electric heat). The second configuration is intended for heat pumps (requires a binary output to command the compressor, a binary input to monitor compressor status, and another binary output to command the reversing valve). Note that cooling performance is also evaluated for heat pumps.
