There is nothing complicated about operating and maintaining your Thermo
King unit, but a few minutes studying this manual will be time well spent.

Performing pre-trip checks and enroute inspections on a regular basis will
minimize operating problems. A regular maintenance program will also help
to keep your unit in top operating condition. If factory recommended
procedures are followed, you will find that you have purchased the most
efficient and dependable temperature control system available.

All service requirements, major and minor, should be handled by a Thermo
King dealer for four very important reasons:

• They are equipped with the factory recommended tools to perform all
service functions

• They have factory trained and certified technicians

• They have genuine Thermo King replacement parts

• The warranty on your new unit is valid only when the repair and
replacement of component parts is performed by an authorized Thermo
King dealer

Unit Description

TriPac Envidia is an all-electric, battery based Auxiliary Heating and Cooling
Temperature Management System. TriPac Envidia allows drivers to reduce
unnecessary truck engine idling, conserve diesel fuel and save money.

TriPac Envidia’s air conditioning provides sleeper compartment cooling in
hot conditions. An optional fuel-fired air heater provides sleeper
compartment heating in cold conditions. The all-electric operation and
noise-dampening construction provides quiet operation for uninterrupted
rest.

Thermo King’s patented battery charging technology automatically
maintains and charges the TriPac Envidia batteries when the tractor is on the
road.

Optional Shore Power Converter provides the capability of running the
TriPac Envidia system or charging the batteries if 115 Vac 15 Amp electrical
power is available.

NNoottee:: The system is designed for overnight driver comfort. Several hours of

drive time are needed to charge the TriPac Envidia batteries before the
next TriPac Envidia operation. Layover of more than one night may
exhaust the TriPac Envidia battery reserve.

Unit Features

• Easy to operate HMI Controller.

• Superior truck cab sleeper compartment cooling.

• Quiet and efficient variable speed hermetic (sealed) air conditioning
compressor.

• Smart Charger Modules (SCM) ensures proper charging and discharging
of the TriPac Envidia and tractor batteries to promote maximum battery
life.

UUnniitt DDeessccrriippttiioonn

time the operator should take steps to conserve power reserve by reducing
power consumption, especially when outside temperature is high.
Suggested steps include:

• Keep window curtains closed to reduce radiant heat that will increase cab
temperature.

• Close curtain between cab and sleeper overnight to reduce air
conditioning load.

• Limit the on time and number of cab lights and accessories to reduce
battery power drain.

• Limit the on time and number of devices or appliances connected to the
optional AC Power Inverter to reduce battery power drain.

• Plug into shore power when available. An optional power converter
provides an additional source of power that will extend operation time.

System Components

The TriPac Envidia system includes several major components:

• Battery Box

• Condenser

• Evaporator/Control Box

• HMI Controller

• Heater (Optional)

• 1000 Watt Inverter (Optional)

• AC/DC Shore Power Converter (Optional)

Battery Box

The battery box is mounted to the truck frame rail. The battery box contains
four Thermo King NXT Absorbed Glass Mat (AGM) Deep Cycle batteries.
These batteries have been specifically designed for the TriPac Envidia
system to maximize battery life and support deep discharge cycles. They
provide increased power storage capacity for the system. The batteries are
automatically charged by the tractor’s alternator when the tractor is on the
road.

Thermo King recommends that the tractor’s batteries also be of the same
type as the TriPac Envidia batteries for optimum performance and battery
life.

Do not use the TriPac Envidia batteries to jump start a vehicle. Severe
damage to the TriPac Envidia batteries and electrical system will result.

Figure 2. TriPac Envidia Battery Box

Evaporator/Control Box

The air conditioning evaporator/control box is typically installed under the
bunk in the truck cab sleeper compartment. Air ducts from the evaporator/
control box distribute cool air throughout the sleeper compartment.

The base controller and the electrical connections for the individual
component are located on the side of the evaporator.

Condenser and Receiver Drier

The air conditioning condenser is mounted on the back of the truck cab. It
contains a variable speed fan. The receiver/drier and the ambient
temperature sensor are integrated on the housing.

Figure 4. Condenser and Receiver Drier

HMI Controller

The HMI controller is typically mounted in the bunk area. The HMI allows the
driver to select the desired function of the system. It also provides alarm,
battery level and system status feedback to the driver. The HMI has three
selector knobs and a battery monitor display. The HMI also contains an
integral Cab Temperature Sensor that helps control cab temperature when
the TriPac Envidia air conditioning system is operating.

UUnniitt DDeessccrriippttiioonn

Optional Heater

The optional fuel-fired air heaterTriPac Envidia Heater is typically installed in
the cargo compartment under the truck cab sleeper compartment. It draws
fuel from the truck’s diesel fuel tank and electric power from the TriPac
Envidia batteries.

Figure 6. Heater

Control Circuits

The primary control circuits operate on 12 Vdc supplied by the system
batteries. The compressor control circuits operate on 230 Vac supplied by
the Compressor Drive Module.

Power Sources

All of the onboard batteries of a truck with the TriPac Envidia system can be
thought of as a reservoir of electrical power. When the truck is parked, the
TriPac Envidia system, and any other electrical devices in use, will consume
the power in this reservoir. The faster the power is consumed the sooner the
reservoir will be empty.

TK 56460-19-OP-EN

17

UUnniitt DDeessccrriippttiioonn

NNoottee:: Use of truck accessories such as lights, refrigerators, TVs, etc., draws

power from the batteries and will compete with the climate control
electrical demand of the TriPac Envidia system. Heavy use of these
devices and/or use of the optional 12 Vdc to 115 Vac Power Inverter
will reduce the potential run time of the TriPac Envidia system. In
addition, high ambient temperature will cause near continuous
operation of TriPac Envidia air conditioning system and is aggravated
by lowering the setpoint. This increased electrical demand will reduce
the number of hours the system can control cab temperature. In high
ambient conditions the driver should reduce the use of electrical
accessories to a minimum to extend air conditioning time.

The TriPac Envidia power management technology will make the most
efficient use of the available power. The system will draw from the truck
batteries and TriPac Envidia battery pack together. There is a Current Sensor
around the interconnect cable between the TriPac Envidia batteries and truck
batteries. It provides the Base Controller with information to help manage
power flow. A pair of Smart Charger Modules (SCM) monitor and control
power flow to and from the TriPac Envidia batteries. The SCMs provide the
Base Controller with battery status information. The TriPac Envidia system
may draw in excess of 80 amps during full air conditioning demand.

Power for the TriPac Envidia system comes from the following three
sources. All system power is sent to a main fuse block in the TriPac Envidia
battery box.

TTrriiPPaacc EEnnvviiddiiaa BBaatttteerryy BBooxx:: The TriPac Envidia Battery Box is the primary
power source for the TriPac Envidia system.

TTrruucckk BBaatttteerriieess:: The OEM truck battery bank is the secondary power source
for the TriPac Envidia system.

SShhoorree PPoowweerr ((OOppttiioonn)):: The optional Shore Power Converter is a 115 Vac to
12 Vdc power converter that provides low voltage power to the system. The
Converter will help extend operation of the system before the batteries are
depleted when the truck is parked and plugged into 115 Vac external or
“Shore Power.” During moderate ambient temperature conditions with
moderate air conditioning demand the converter may support the system
without draining the batteries. During high ambient temperature conditions
with high air conditioning demand the converter will extend the operating
time before the batteries are depleted. The Converter may also act as a
secondary battery charging method during periods of low air conditioning or
heating demand. The Converter is mounted in the cab, usually under the
bunk. If the Shore Power Converter is plugged in while TriPac Envidia and all
truck systems are off the converter will charge the Envidia and truck
batteries.

TK 56460-19-OP-EN

UUnniitt DDeessccrriippttiioonn

If shore power is available, it should be connected when the batteries are
near full charge to receive the full extended run time benefit of the Shore
Power Converter.

Truck Integration

The TriPac Envidia APU system is integrated with the following OEM Truck
systems.

OEM Battery Pack

The OEM truck batteries provide part of the power for the TriPac Envidia
system. For base level system performance, there must be four 12 Vdc
Group 31 batteries connected to provide 12 Vdc output. For optimum system
performance the truck battery pack should be upgraded to four AGM type
deep cycle batteries. These batteries have been specifically designed to
support deep discharge cycles. Shorter system runtime will be experienced
without the battery upgrade.

Alternator

The OEM truck alternator provides primary battery charging for the system
while the truck is driving. It should be upgraded to a minimum of 270 amps.
With some applications or truck operation profiles, such as short drive times
or high system demand, increased battery charging capacity may be
required. To provide the additional charging capacity the alternator and
charging cables may need to be upgraded to 300 amps or above. Alternator
and harness upgrades must be approved by the truck OEM.

Ignition Switch

When the truck ignition switch is turned to the On or Run position a signal is
sent to the TriPac Envidia Base Controller. A three minute “Pull ahead” timer
is activated and the system will continue to operate. If the switch is still on
after three minutes the TriPac Envidia system will be turned off (disabled)
and the system will begin a shutdown sequence. Once the sequence is
complete, the system does not draw power from the batteries. The time
delay prevents short cycling the system during short duration engine
operation. If the truck engine continues to run, the battery charging process
will begin. When the truck ignition is turned off, the TriPac Envidia system is
defaulted off (disabled) and must be turned on (enabled) by the driver.

HMI Control Panel Operation

The TriPac Envidia is operated using an HMI (Human Machine Interface)
Control Panel which is typically mounted on a wall in the truck cab sleeper
compartment.

Figure 7. HMI Control Panel

HMI Control Panel Display

The HMI is an easy to use control that allows the driver to select the desired
function of the system. It also provides feedback to the driver of alarms,
battery level and system status. The HMI has three selector knobs and a
battery monitor display. The HMI also contains an integral Cab Temperature
Sensor.

The driver can select these functions from the HMI:

• System On/Off

• Mode (Cool, Fan, Heat)

• Desired Cab Temperature (Cooler or Warmer)

• Fan Speed (OFF, Auto, Variable)

• Driver Selectable Settings

When any setting change occurs, there will be a two second delay before the
controller recognizes the new setting. The Mode Icon will flash until mode is
confirmed by the Base Controller.

Battery Charging

Truck Running

Charging amperage is provided by the truck alternator. A 270 amp alternator
is the minimum required to support the TriPac Envidia system. For many
applications or truck operation profiles, such as high tractor duty load, high
driver “Hotel Load”, extended layover duration, high ambient temperature
or short drive times between layovers, increased battery charging capacity
may be required. Undersized alternators will increase TriPac Envidia charge
time. The truck alternator will spend a higher percentage of operating time at
maximum output. This may shorten the life of the truck alternator. To
provide the additional charging capacity, the alternator and charging cables

TK 56460-19-OP-EN

29

OOppeerraattiinngg IInnssttrruuccttiioonnss

will need to be upgraded to 270 amps or more. Verify that alternator and
charging cable upgrades are accepted by the truck OEM.

Battery charging will take place in progressive stages that prevents an
extremely high alternator charge rate. The process begins when the truck
engine is started. The SCMs will be put in Null mode. All TriPac Envidia
batteries will be isolated. The truck batteries will begin charging first.

NNoottee:: While the truck is idling there may not be enough amperage produced

by the alternator to effectively charge the batteries. Many alternators
may require a minimum of 1,200 RPM before effective battery
charging is available.

If the TriPac Envidia system is on when the truck is started, the three minute
Pull Ahead timer must expire followed by a four minute system check before
the charging process will begin. If the TriPac Envidia system is off when the
truck is started, the Base Controller wakes up to check IGN circuit status
periodically (every five minutes during first three days, every 15 minutes
days 4-6, once per hour after day 6). If it is on, the charging process will
begin.

The TriPac Envidia Base Controller will monitor System Voltage. When it
rises above 13 Vdc, the Base Controller will begin adding one SCM at a time
to the charging process if there is excess charging capacity available from
the alternator. Each SCM is capable of charging one battery at 40 amps. First
the Base Controller will check each battery. It will put one of the SCMs in
Charge mode. It will then choose to charge the battery with the lowest state
of charge. As a result, SCM1 battery A may not be the first to begin charging.

NNoottee:: A battery must be above 9.5 volts for the SCM to recognize it for

charging. A battery below this voltage should be tested then
externally charged before adding it back into the system. A red
flashing LED on the SCM will indicate a battery that is under voltage
and isolated.

If System Voltage does not drop significantly when a battery is added, the
SCM will remain in Charge mode. If System Voltage does drop there is
insufficient reserve charging capacity, the truck batteries are not sufficiently
charged. The SCM will return to Null mode for 15 minutes then retry. The
SCM will continue trying to engage Charge mode until it is successful.

Once the first SCM is in Charge mode for a time the Base Controller will
attempt to add the second SCM to the charging process. It will perform the
same steps until it has both SCMs charging one battery each. The truck
alternator is now charging six batteries; four in the truck and two in the
TriPac Envidia battery box. The SCMs will bring their first batteries to 80%
state of charge then switch to their second batteries until all batteries are at

30

TK 56460-19-OP-EN

OOppeerraattiinngg IInnssttrruuccttiioonnss

80% state of charge. The SCMs will switch back to the first battery to finish
charging to 100% followed by the second battery. Once charging has started,
if System Voltage falls below 11.5 Vdc, the TriPac Envidia battery charging
will stop.

Total battery charging time is expected to be 4 to 8 hours depending on
depth of discharge, traffic, driving profile and alternator size. The six Battery
Monitor bars will scroll up in green while the truck engine is running and
alternator is charging. Battery charge state can be read at the HMI while the
HVAC system is off by bumping the On/Off selector for less than one second.

Shore Power

Connect the optional 115 Vac to 12 Vdc Shore Power Converter to external
Shore Power. Requires a 115 Vac, 15 amp power source. If the optional AC to
DC Shore Power Converter is installed and Shore Power is available it should
be connected to external power as soon as possible after the truck is parked.
The converter will provide 13.6 Vdc at up to 85 amps to the truck batteries.
This additional amperage helps to keep the truck batteries at a high state of
charge while supporting driver “Hotel Load” and power sharing with the
TriPac Envidia system. The primary function of the AC to DC Shore Power
Converter is to extend HVAC operating time.

NNoottee:: The Shore Power Converter should not be connected if the truck is

running.

HVAC System On

If the combined amp draw from the truck batteries of the TriPac Envidia
HVAC system, truck systems and DC to AC Power Inverter is less than the
available 85 amp output of the AC to DC Shore Power Converter, the truck
battery pack may begin charging. The TriPac Envidia batteries will not
charge with the HVAC system on.

HVAC System Off

The Base Controller monitors System Voltage. While the system is off, the
Real Time Clock momentarily wakes up the Base Controller periodically
(every five minutes during first three days, every 15 minutes days 4-6, once
per hour after day 6). It will check System Voltage. If it rises above 13.5 Vdc
the system will automatically recognize Shore Power Charging and enter
charge mode. This will allow the SCMs to charge the Envidia batteries. If
System Voltage falls below 13 the charging of the Envidia batteries will stop.
The truck batteries will continue to charge.
