-
The splitting of the zones for multi-temperature operation must be as stated in the qualification test: 2/3 and 1/3.
-
For the configuration trailer with S3A, Zone 2 maximum split must be 1/3. If a larger Zone 2 compartment is required, please consult with your Thermo King Dealer.
When operating in multi-temperatures mode:
-
For A-500 Spectrum with S3A remote evaporator software version must be equal to or higher than v.3.0.2.
-
CONTROLLING SENSOR for both FRESH and FROZEN range is set RETURN AIR for Zone 1.
-
Blower speed for DIESEL operation pull down and steady state is set HIGH.
-
Blower speed for ELECTRIC operation pull down and steady state is MAXIMUM.
-
Customers who will use the mentioned equipment as a single-temperature unit, the dividing door must be stowed in such a way that it does not interrupt the airflow from the main host unit evaporator and, Zone 2 must be switched off.
