1.1 About this Manual

1.1.1 What It Contains

This manual contains all the information needed to configure and operate the 1ZC, 16C,

18C, and 25C controllers. (The 19C is functionally identical to the 18C.)

This manual contains:

• in this section, an overview of the controllers’ capabilities

• a description of the user interface and instructions for using the display and

keypad on the 16C, 18C, and 25C controllers; see Section 2

• quick-start instructions for setting up the 16C, 18C, and 25C controllers for PID

control, using many of the factory defaults; see Section 3

• general information about configuration parameters; see Section 4

• detailed information about every configuration parameter used by the controllers;

see Sections 5 through 14

• numbers used to identify the parameters in Multi-Comm messages; see Section

• tuning instructions (for automatic and manual tuning); see Section 16

• instructions for changing the security access level; see Section 17

• calibration instructions; see Section 18; the controller is calibrated at the factory

for the sensor type specified when you ordered the controller. However, if you

later change the type of sensor, you may need to re-calibrate. The circumstance

that dictates re-calibration is explained in 5.2.

• error messages and codes displayed on the front panel of 16C, 18C, and 25C

controllers; see Section 19

• frequently asked questions; see Section 20

Instructions for wiring and mounting the controllers are in the installation manual supplied

with each controller.

Guidelines for using a MODBUS host to communicate with the Series C controllers are in

Using the MODBUS Protocol with Athena Series C (1ZC, 16C, 18C, and 25C)

Controllers. That manual also contains the MODBUS register mapping for all values

stored in the controllers’ databases.

Instructions for configuring and monitoring the 1ZC, 16C, 18C, and 25C controllers using

an RS-232 or RS-485 interface, and Athena Multi-Comm software are in the Multi-Comm

User’s Guide.
