7 Operation
7-1 Introduction
Standard FSS Series circulators use a microprocessor-based PID
controller. The controller is a modular, self-contained unit that can
slide from its mounting housing. It is factory set and adjusted; no
field adjustment to the internal controls is necessary.
Control Operation Range
Standard models 50°F to 70°F (10ºC to 21ºC)
7-2 Setting Process Water Temperature
To change the process water temperature set point:
• Press the Up Arrow button to raise the set point.
• Press the Down Arrow button to lower the set point.
7-3 LED Indicators
PV or Process Value Numeric LED
During normal operation, the large red PV LED on the controller
displays the actual process temperature at the To Process
thermocouple. It also lists parameter symbols during setup and
error messages if an error occurs.
SV or Set Value Numeric LED
During normal operation, the green SV LED on the controller
displays the process set point you want the circulator to maintain.
It also displays parameter and pre-set function values during setup.
C LED
The orange C LED lights when the control output energizes the
hot-gas bypass solenoid valve.
