Unit Description
35
Refrigeration Cycles
All Zones Cooling
When all zones are cooling the unit condenser is
used to eliminate the heat from all zones. This is a
Conventional Cooling cycle.
One or Two Zones Cooling and
Other Zones Heating
When at least one zone is cooling and another zone
is heating, the evaporator in the heating zone is used
as a condenser to remove the heat from the zone that
is cooling. The unit condenser is not used. This is
Reverse Cycle.
• Invertible System - If a zone is capable of
reverse cycle operation it is said to be invertable.
Reverse cycle means that the evaporator coil in
that zone is used as the condenser coil during
heat operation as long as at least one other zone
is operating in cool mode. All invertable
systems are capable maintaining any
temperature in any zone and can also heat or
cool in any zone at any time
All Zones Heating
When all zones are heating the unit condenser is not
used. This is Hot Gas Heat operation.
Any Zone Defrosting
When any zone enters defrost, zones that are cooling
or heating are placed in Delayed Cool/Heat mode.
The unit condenser is not used. Defrost is
accomplished by means of Hot Gas Heat.
Technician Features
The Thermo King SPECTRUM
™
TS control system
features many special technician functions. These
functions are available from the Maintenance
Menus. A brief explanation of each menu is
included here. For additional details refer to the
SPECTRUM
™
TS Microprocessor Diagnostic
Manual.
Hours Display Menu: The Hours Menu allows the
operator to check the readings of all unit
hour-meters that have been enabled. In addition, a
reset button is provided for each user programmable
hour-meter.
Gauges Display Menu: The Gauges Display allows
the operator to display the unit operating gauges
such as coolant level and temperature, engine RPM
and suction and discharge pressure.
Sensors Display Menu: The Sensors Display allows
the operator to display the temperature of all unit
temperature sensors and the temperature differential
for each zone.
Service Test Mode Menu: Since it is impossible to
predict exact operating conditions, a
trouble-shooting feature called Service Test Mode
has been incorporated. This feature allows the unit
to be “forced” to a known set of operating
conditions in Diesel mode, regardless of setpoint or
temperature sensor inputs. Service personnel can
now troubleshoot the system under defined
conditions. Service Test Mode can be used with the
unit running or shut down.
When a Service Test Mode function is selected, the
unit will operate in that mode for 15 minutes. If no
other Service Test Mode function is selected during
this time the unit will shut down and generate Alarm
Code 54. All protection circuits operate normally in
Service Test Mode. The Service Test Mode display
also shows return air temperature, discharge air
temperature, evaporator coil temperature and the
calculated value for temperature differential. The
Gauge Menu is also available.
Interface Board Test Mode Menu: Interface Board
Test Mode allows individual relays or outputs to
be energized. This permits service personnel to
troubleshoot the system under defined conditions.
Interface Board Test mode is use with the unit
shut down.
Relays and outputs can all be energized
momentarily. In addition, all functions except the
Preheat relay and starter can be locked on. If a
function is locked on that function will remain
energized for 15 minutes if no other Interface
Board Test Mode function is selected.
At the end of 15 minutes, if no other function is
selected the unit will shut down and record Alarm
Code 54. All protection circuits operate normally in
Service Test Mode.
The Interface Board Test Mode display also shows
suction pressure, discharge pressure, amps and
battery volts.
