Introduction

WARNING: The TAP controller is not a safety device. The controller provides 12VDC outputs to operate relays, which in turn enable/disable heating elements. It is possible for relays to fail in the on position. This controller cannot protect against relay failure. Use this controller at your own risk.

NEVER LEAVE THE KILN UNATTENDED! 

The Temperature Automation by Proportional Integral-Derivative (TAP) controller provides a temperature control solution, which incorporates a Graphical User Interface (GUI). This controller is designed to take the guess work out of firing schedule creation, modification, execution, and monitoring.

The intuitive touchscreen interface utilizes a smart-phone like UI to enable immediate out of the box use. This unique design approach alleviates the need to continually refer to this User Manual for performing the most basic tasks.
