Parameters - Conair Thermolator TW-1 User Manual

You can establish a normal operating range around the process
temperature setpoint using the high and low deviation parame-
ters. If the process temperature exceeds the high deviation
limit, or falls below the low deviation limit for longer than the
set delay time, the Thermolator alerts you to the unacceptable
temperature variation with an alarm light, and optional audible
or strobe.
These temperature deviation limits will adjust automatically
relative to the process temperature setpoint.
The factory default setting for both the high and low deviation
parameters is 25°F. These parameters are adjustable to estab-
lish a narrower or wider acceptable temperature band for nor-
mal operation.
To change the temperature deviation settings:
1
Press the Setpoint Select
button to select the deviation para-
meter you want to change.
Use the s and t setpoint
2
buttons to enter the deviation tem-
perature. The setting is stored in
memory even when the power is
turned off. The recommended set-
ting is ± 2-10°F.
NOTE:
If you enabled passcode protection, you must enter
the passcode to change this parameter. To enter the pass-
code:
Hold down the Setpoint Select button for 5 seconds. When
the control displays " 1 PaS", use the setpoint adjustment but-
tons to enter the passcode. Press the Setpoint Select button
again. If the correct passcode was entered the controller will
display ACC PAS for 3 seconds. If the passcode was incor-
rect, the controller will display rEJ PAS (rejected passcode).
Access to system parameters remain until power is cycled or
the RUN or STOP button is pressed.
