UNIT DESCRIPTION
THERMO KING SMART REEFER 2
(SR-2) CONTROLLER
Your SLX unit uses the SR-2 control system to
operate cooling, heating, and defrost functions.
SR-2 - SLX Single-Temperature
SR-2 - SLX Spectrum
See Controller Description on page 9 for more
information about SR-2 controller.
CYCLE-SENTRY START/STOP
CONTROLS
The CYCLE-SENTRY system automatically
starts up the unit when heating or cooling is
required and shuts it off when the cargo box
temperature reaches the controller setpoint.
The CYCLE-SENTRY system also maintains
engine temperature by restarting the unit if the
engine block temperature drops below -1°C. It
runs until the controller demand is satisfied and
the engine block temperature reaches 32°C.
CYCLE-SENTRY is designed for use only
with products which do not require tight
temperature control or continuous airflow, such
as all deep frozen products and non-perishable
non-frozen products.
The start/stop nature of CYCLE-SENTRY does
not satisfy the temperature control or airflow
requirements for perishable or temperature
sensitive products. Thermo King therefore does
NOT recommend the use of CYCLE-SENTRY
control for these products.
DEFROST
As the unit is operated to cool the trailer, frost
will gradually build up on the evaporator coils.
Periodically this frost must be melted to
prevent loss of cooling and airflow.
MODULATION
Systems equipped with modulation can provide
precise temperature control of fresh products.
This can reduce product dehydration, increase
product shelf life and protect fresh products
from freeze damage.
