4. General Information About

Configuration Parameters

4.1 Information in This Section

This section contains general information about the configuration parameters used by the

1ZC, 16C, 18C, and 25C controllers.

Sections 5 through 14 contain information about

functional groups of parameters. Each section describes the parameters in a single

configuration menu. If you have used Athena Series C controllers before, and plan to

use PID control (the default), then these sections probably contain more information than

you need. Go back to Section 3. It contains instructions for doing the minimum to get a

16C, 18C, or 25C controller up and running using PID control (and most of the other

configuration defaults).

However, if you are a new user of Athena Series C controllers, or plan to use an option

you have not used before, then refer to this section, as well as Sections 5 through 14, for

the information you need.

The parameters apply to 1ZC controllers, even though they have no display and no keypad. Model

1ZC controllers (as well as 16C, 18C, and 25C models) can be configured using a host computer and

serial communication, with configuration software such as the Athena Multi-Comm application (using

Athena Plus protocol) or MODBUS-compliant software. For a controller to use Athena Plus protocol to

communicate with a Multi-Comm host or to use MODBUS to respond to a MODBUS master, the

controller must support serial communications and contain the appropriate communication firmware. To

determine what option(s) a new controller supports, compare the model number on the controller label

with the model number information in the installation manual supplied with the controller.
