Automatic Data Acquisition:
Connect serial cable to PC serial port. To enable data acquisition logging mode use
command El. The command E0 will disable logging mode. Enable and disable
commands are stored in permanent non-volatile memory.
When running in logger mode, the unit will send set and actual fluid temperature
readings to the RS232 port in an ASCII format. Use download feature in
communications software and specify ASCII file format. Once saved, data file can be
imported to any software that accepts an ASCII file.

Selects the temperature below which refrigeration is activated.
For most applications, we recommend setting Auto Refrig at 15°C above room
temperature. For energy savings you may select a lower value. This may effect the rate
of cooling down from a higher temperature. For fast cool downs from high temperature,
select the highest allowable value. (Models vary in allowable temperatures.)
Some programmable models are not equipped with a refrigeration system. For
operation of these non-refrigerated models, the included cooling coil may be used to
achieve bath temperatures within 15°C above the ambient room temperature. The
cooling coil also permits the bath temperature to be lowered more rapidly, after
operation at an elevated temperature. The cooling coil connections are located
between the circulating pump’s inlet and outlet connections at the rear of the bath’s
controller. To use the cooling coil, slide the

in. ID latex tubing from the water source
over one of the coil’s connections and route another length of tubing from the other coil
connection to the drain.
3.4 Setting the Safety Thermostat
The Over Temperature Protection (OTP) thermostat safety
feature prevents your unit from over heating, in case of
primary controller failure or a low liquid condition, by
switching off power to the heater. This feature is independent
of the high limit setting and has a range of 60°C to 220°C
The high limit must still be set (refer to FCN 2, Setting The
High Limit.)
For Temperatures Less Than 60°C:
1. Turn the OTP thermostat (at the rear of the controller) fully
counterclockwise ( - ) 240 volt models have a recessed slot
that is to be set with a standard screwdriver.
For Temperatures Over 60°C:
1. Turn the OTP thermostat (at the rear of the controller) fully clockwise ( + ) until it stops.
240 volt models use a screwdriver.
2. Stabilize the bath at your applications highest set temperature.
3. Turn the OTP slowly counterclockwise ( - ) until you hear a click.
The unit will STOP and the display reads . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
4. Turn the OTP clockwise ( + ) slightly above the position where the unit tripped then
reset the OTP thermostat breaker by pressing the OTP reset. OTP is now set to
trip a few degrees over the stabilized fluid temperature.
5. Press to restart.
