Chapter 4 – Temperature Controller

Profile Programming
The Series F4 Temperature Controller can be programmed to store up to 256 steps into as many
as 10 profiles. You do not need a computer to enter a profile – it can be easily done through the
controller’s front panel keys. A Profile is a set of instructions programmed as a sequence of
steps. The controller handles the profile steps automatically, in sequence. As many as 40
different profiles and a total of 256 steps can be stored in non-volatile memory. The 256 steps are
grouped by profile. So, one profile could have 256 steps; or 39 profiles could have 6 steps and
one could have 22; or 32 profiles could have eight steps each. The maximum number of steps is
256, and the maximum number of profiles is 40.
Step Types
Use the six available step types – Autostart, Ramp Time, Ramp Rate, Soak, Jump and End – to
create simple or complex profiles involving all inputs and outputs. The Series F4 prompts you to
define each step’s properties.
Autostart Step
The use of an Autostart step in a profile is optional. Autostart pauses a profile until the specified
date or day, and time (of a 24-hour-clock). Define the Autostart by choosing:
• Day (of the week) or Date,
• Time
To invoke an Autostart step in a profile, you must activate the profile via the Profile Key and
select the Autostart step.
Ramp Time Step
Ramp Time changes the set point to a new value in a chosen period of time. Define the Ramp
Time step by choosing:
• *Wait for an event or process value
• Event outputs 1 through 7 to turn ON or OFF (For controlling the power to remote devices.)
• Time (in hours, minutes and seconds)
• Temperature Set Point
• PID set (One of five sets of PID tuning parameters. Normally, just leave at PID Set 1.)
• **Guaranteed Soak
Ramp Rate Step
Ramp Rate changes the set point to a new value in a chosen rate of time. Define the Ramp Rate
step by choosing:
• *Wait for an event or process value
• Event outputs 1 through 7 to turn ON or OFF (For controlling the power to remote devices.)
• Rate (in degrees per minute)
• Temperature Set Point
• PID set (One of five sets of PID tuning parameters. Normally, just leave at PID Set 1.)
• **Guaranteed Soak
