Vector Lab Products Refrigerators and Freezers 7
Controller Operation
In normal operation, the controller will display temperature in degrees Celsius. To change from Celsius to
Fahrenheit requires a programming key. Contact Vector Products Parts Department at 1-855-686-5592 for
part numbers and pricing.
CAUTION! Vector Lab Products does not authorize changing any critical operating parameters
as it can cause improper system operation and/or severe mechanical damage.Changing
operating parameters may result in Vector Lab Products voiding equipment warranty.
Refrigerators come pre-programmed with a 4 C (39.2 F) set point. Standard operating temperature at default is
4C to 6 C (39.2 F to 42.8 F)
If desired, the refrigerator’s set point can be adjusted within a 1 C to 12 C (33.8 F to 53.6F) range.
Freezers are pre-programmed with a –25 C (–13 F) set point. If desired, the freezer’s set point can be adjusted
within a –23 C to –10 C (-13 F to 14 F) range
All set points have a +2 C (+3.6 F) differential (r0 setting on the controller). The 2.2 C (3.6 F) differential means that
with a 4 C (39.2 F) set point, the compressor will turn off at 4 C (39.2 F) and turn on when it reaches 6C (42.8 F).
It is important to understand that the set point equals the compressor cut out.
