I. Overview
This device consists of a temperature monitor and electronics created to control a
chiller and/or a heater, based on the temperature reading. Accordingly, the
temperature setpoints must be set before putting the controller into service. After
the controller is in service, it will be necessary to re-confirm proper probe
placement and temperature reading.
It is important that you understand these instructions and it is critical that you
follow the cautions in this manual. Users will be controlling EITHER a chiller OR a
heater; or BOTH a chiller AND a heater with this instrument. It is critical that one
pay special attention to the placement of the temperature probe in the system. You
must frequently check the condition and location of the temperature probe. Control
electronics are not human, they are not intelligent and they can not “know” when
something has happened to make their input or output invalid. If the probe is not
immersed in the system, it will no longer be reading the correct temperature.
Installing a temperature controller on your system does not mean that you no
longer have to pay attention to it. You must still monitor the system so that you
can note when a problem exists and correct it in a timely fashion.

Temperature Probe
UPPER LEFT (Temperature Display)
The 3 1/2 digit LCD (Fig. A) at the top left of the controller displays a
numeric value corresponding either to the temperature as measured through the
probe, or the high or low controller setpoints.
LOWER LEFT (temperature monitor power & instrument status)
Below the display are two red LED lights.
The red POWER LED (Fig. B) is illuminated when the power is turned on to
the controller.
The TEMP LED (Fig. C) is illuminated when the display is indicating the
temperature as measured by the probe. The TEMP LED is off when the display is
indicating either the high or low controller setpoints.
CENTER (Controller Setpoint Block)
There are two potentiometers that are used to adjust the controller
setpoints. They control the RANGE (Fig. D) and CENTER VALUE (Fig. E) of the
