HEALTHCARETM
Operation
The temperature control board and probe indicate when the refrigeration system is required to turn on and off.
The refrigeration system removes heat from the cabinet interior and rejects it to the surrounding room air.
When the cabinet interior temperature rises above the controller cut-in temperature, the controller turns the
refrigeration system on. The controller energizes the evaporator fan and solid-state control relay which energizes
the condensing unit. The compressor uses a current-style starting relay and a starting capacitor to start the
compressor motor.
When the cabinet interior falls below the predetermined cut-out temperature, read by the P1 (control probe), the
controller de-energizes the solid state compressor relay and condenser fan motor. The additional evaporator fan
run-time is dependent upon the delay setting programmed within the controller menu.
Any accumulated frost on the evaporator coils melts during the off cycle. The condensate drains out of the unit
to the condensate tray to the left of the condensing unit. The heat from the condensing unit evaporates any
condensate in the drain pan.
Temperature Control
The temperature control system is preset by the factory to maintain a product temperature of 4.4C (40F). If
desired, the set-point temperature can be raised as high as 10 C (50F) by following the instructions in Controller
Operation on page 8 for changing the temperature set point.
Defrosting
Performance Plus undercounter refrigerators do not require manual defrosting. The unit cooler defrosts
automatically when the condensing unit is in the OFF cycle and during an off time defrost every 8 hours. The
defrost will terminate when the cabinet temperature read via the P1 control probe reaches 3.3 C (38 F) or after
60minutes.

Controller Operation - Performance Plus
In normal operation, the controller displays product temperature in degrees C (default) or user-selected degreesF.
The controller is pre-programmed with a 4.4 C (40F) set point. COMP displays when the compressor is running.
If this set point does not meet your specic application needs, instructions for changing the set point are found
below.
Note: Follett presets its refrigeration system to hold product temperature at approximately 4.4 C (40F). If you are
using this in a food service application, and installing in accordance with NSF, you must set the control set-
point to 3.3 C (38F). This will deliver a product temperature below the 4.4 C (40F) NSF requirement.
Controller Display
The controller display will show the product/bottle temperature in degrees C or degrees F as selected by the user
except when the unit is in an alarm.
The controller has system indicators above the temperature display to let you know when: the compressor is
energized (COMP), the evaporator fan is energized (FAN) or the unit is in defrost (DEF).

To acknowledge the alarm press and hold set until the RST is displayed.
Alarming Contacts (Touchscreen units only)
This unit is equipped with dry contacts that may be connected to a 3rd party monitoring system. The contacts are
located on the back of the unit. Standard Performance Plus units utilize the Alarm 1 set (top 3). Each set of dry
contacts has a Common, a Normally Open and a Normally Closed connection point. By default, Alarm Relay 1
is set to activate with any of the following alarms: Alarm 1 High temp, Alarm 1 Low temp, System errors or probe
error.
Probe calibration
The temperature probes can be calibrated from –9.9 to +9.9. The calibration is in the second level menu under
