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 evaporator fan
continuously runs to acheive desired product temperature.
Any accumulated frost on the evaporator coils melts during the electric defrost 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 cabinet temperature of –28C (–18toF). If
desired, the set-point temperature can be raised as high as –17C (0F) by following the instructions in Controller
Operation on page 6 for changing the temperature set point. The 2.2 C (4F) differential will be maintained
regardless of the controller set point.
Defrosting
The Performance Plus freezer is equipped with an electric defrost to keep the evaporator frost free. Defrost cycle
terminates after 30 minutes or when the evaporator reaches 5 C (41 F) as read via the P2 (defrost) probe.

Controller Operation - Performance Plus
In normal operation, the controller displays cabinet temperatures in degrees C or user-selected degrees F.
F temperatures are displayed to the nearest degree and C temperatures are displayed to one decimal point.
The controller is pre-programmed with a –28C (–18to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.
Controller Display
The controller display will show the 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).

Start-up alarm delay
The Performance Plus unit has a 120 minute time delay between when the unit is energized to when the
temperature alarms become active. This delay can be change in parameters in the controller under Alarm
Startup Delay (ASd).

The mute button is used to temporarily mute the audible alarm for 10 minutes. If the alarm condition of the unit
has not changed in 10 minutes, then the alarm will sound again.
Alarm acknowledgement and alarm Reset
The alarm will need to be acknowledged after the alarm condition has been resolved, before the alarm will reset.
To acknowledge the alarm press and hold set until the RST is displayed.
Alarming Contacts
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
