Chapter 4 - Temperature Controller
Introduction
The Series F4 Temperature Controller can function as either a single set point controller (static
mode) or as a programmable profile controller. A four-line LCD display facilitates setup and
programming, and presents informative messages about status, error, and alarm conditions.
Digital outputs, profiles, and alarms can be named for easy reference. An Information Key gives
you quick information about the pages, menus, parameters and values, as well as error and alarm
conditions if they occur. The user-interface is organized into five “pages” of menus.
NOTE: If your chamber was ordered with the F4T Touch Screen Controller, see the
separate manual for that controller.
! CAUTION: The Series F4 “Alarm” functions are NOT used in the chamber’s safety
system and are NOT connected. TestEquity does NOT recommend using the
Series F4 alarm function as the main protection device. The independent
EZ-Zone Limit Controller functions as the main protection device.
! CAUTION: The Series F4 Temperature Controller has been properly configured by
TestEquity to match the chamber’s system requirements and to perform
optimally over a wide range of operating conditions. Improper modifications
to these setup values can result in erratic performance and unreliable
operation. Do not attempt to modify the setup values, unless you thoroughly
understand what you are doing. Setup examples in the “Series F4 User’s
Manual” are NOT applicable to this chamber. If there is any doubt, please call
TestEquity before proceeding. The correct values are documented in the
“Series F4 Temperature Controller Setup Parameters” section of this manual.
! CAUTION: NEVER select “Full Defaults” in the Series F4 Factory/Test Menu. This will
erase all the correct values which are documented in the “Series F4
Temperature Controller Setup Parameters” section of this manual.
Security Features
The Series F4 Controller has several levels of security to prevent unauthorized users from
changing critical configuration parameters. Only the Set Point and Profile menus have “Full
Access”. TestEquity has configured all other menus to “Password”, and have protected them
with a password.
TestEquity does not recommend that these security levels be changed for most applications.
However, there will be times when entry into these menus is necessary. For example, you may
need to gain access to Setup Page in order to change from °C to °F display, or to change the time
or date. You must call TestEquity at 877-512-3457 or 805-480-0638 to obtain the password.
