Microprocessor Control
5-1 Introduction
Standard SMC Series chillers use a microprocessor based 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.
5-2 Setting the Process Water Temperature
•  Press 
 until the 
SP
 indicator lights.
•  Press 
 or 
 to raise or lower the setpoint to the desired leaving water
temperature.
Note: SMC leaving water temperature range of operation is 30ºF (-1
°C) to 65ºF (18°C).
•  Press 
 to display the current process temperature (
SP
 and 
AL
 are off).
5-3 Setting the Alarm Value
•  Press 
 until 
AL
 lights.
•  Press 
 or 
 to raise or lower the alarm value. The factory setting is 
10

should be correct for most processes. Setting the alarm value to 
10
 creates an alarm if the
process temperature rises or falls 10ºF/ºC or more from the chiller process setpoint.
•  Press 
 to display the current process temperature (
SP
 and 
AL
 are off).
