Heating capacities from 23kW to 69kW
Micro-control
Heat pump smart recovery
Optimization of mechanical heating
Auxiliary heating devices only used when necessary
Economizer preferred cooling
To minimize compressor(s) operation in cooling mode
Trane is a rooftop expert.
In order to decrease operational costs, we have designed efficient units
1) gas burner efficiency is around 90%
2) the micro-control optimizes the rooftop operation
a) heat pump smart recovery :
- most of the systems will use all the heating capabilities of the unit when there is a call for heat in order to reach the room setpoint asap.
- our controller will first start the heat pump mode, and use the auxiliary heating devices (electric heater, hot water coil) only if the room temperature recovery is not satisfactory
b) economizer preferred cooling :
- when there is a call for cooling and outside air conditions are suitable for free-cooling, the micro-controller will first try to cool down the building with the outside air, it will turn on compressors only if the room temperature recovery is not satisfactory
- under extreme conditions, the controller may allow free-cooling and mechanical cooling to operate together, thus optimizing the use of free-cooling

Gas burners
Voyager II
Designed and built by Trane
Used for more than 15 years in Trane units
New Voyager I
Made of aluminized steel
People are sometimes afraid of using gas burners on top of their building. Here are the sfety features that Trane units propose.
In addition to the slide we can say that:
- our burners are approved by a notified entity AFNOR, safety and performances
- as part of the whole unit, they are CE approved and can also comply with the European local code (Switzerland, Hungary etc…)
- the pressure inside the drum is smaller than the pressure of the airstream. Therefore, if a hole appears on the drum, there will be no smoke or gas intrusion in the airstream, but on the contrary, the air will be aspired inside the drum and shut it off immediately
Critical components in stainless steel

12. Reliability Micro-control standard features
New Voyager I
Voyager II
Reliability
Micro-control standard features
True anti-short cycle timer on the compressors : 3 min minimum ON & 3 min minimum OFF, ensures proper oil return
Low ambient start timer : bypasses low pressure switch when a compressor starts, eliminates nuisance compressor lockouts
Low ambient operation down to -18°C
Thanks to its intelligent operation, the Micro-controller brings a lot of standard features to improve the reliability of the system.
True anti-short cycle timer : we say TRUE because some competitive units provide a standard anti-short cycle timer which only controls the minimum OFF time of the compressor and not the minimum ON time, which does not insure proper oil circulation.

13. Reliability Micro-control standard features
New Voyager I

Reliability
Micro-control standard features
Easy unit diagnostic on Trane Integrated Comfort System : alarms can be reported to Trane control devices
On board diagnostic & built-in test mode : allows the technician to easily test the unit and find the trouble
Intelligent fallback : control built-in setpoints, allows temporary operation of the units without thermostat
Looking at the service & maintenance side.
On board diagnostic : the LED of the mother board indicates proper operation of the unit.
Built-in test mode : by establishing the contact between 2 identified contacts on the LTB (Low voltage Terminal Board : customer connection board), the technician is able to cycle the operation of each major component of the unit. This helps to quickly identify which one fails.
Intelligent Fallback : if the communication fails between the unit and the thermostat, the technician can take the OA sensor of the unit, place is into the return section and wire it up to the control (on the thermostat connections : LTB 1&2). The unit will then run between predefined setpoint - cooling 23,3°C - heating 20°C. The client does not have to wait to receive a new thermostat to have some airconditioning.

No job site conversion
Big time saving !
Wide range of factory-mounted options
Tested in the factory with the unit
Big time saving !
Factory dedicated airflow : some competitors offer deliver units in downflow configuration, and if the application is horizontal, the installer must convert the unit (ex : Lennox, Linea up to size 55). We do the conversion in the factory for the client (even on the New Voyager I range)
Factory-mounted options : each time an option can be mounted in the unit, we do it in the factory. Only items like room thermostats, roofcurbs, fire thermostat (which must be mounted in the ductwork) etc… have to be mounted on site.

22. Easy and Quick ... To install
New Voyager I
Voyager II
Easy and Quick ...
To install
Duct connection - horizontal configuration
Duct flanges as standard for easier duct connection
Return & supply on the same side to facilitate rooftop positioning against the building
Return & supply direct to the duct : no additional roofcurb needed
Return and supply on the same side : some competitors offer horizontal discharge units with return and supply on different sides of the unit
- this complicates ductwork as you want to hit the buliding on the same side
- there is not always the space on job site to make such a duct network around the unit, especially if the unit has to be installed on the roof in a technical corridor
Return and supply direct to the duct : some competitors do not have true horizontal discharge unit (ex: Lennox, Linéa range, above size 55), and the installer must use a specific roofcurb with lateral discharge to connect the duct
- this is additional component to purchase and additional work
- the supply & return sections are relatively flat
- this increases unit height which may cause visual issues - when unit is mounted on the roof - as the rooftop has to be discrete

23. Easy and Quick ... To install Duct connection - vertical configuration

- Easy connections of the rooftop on the roofcurb as the rooftop overlaps it.
- Easy connection of the ductwork : the ductwork has to be connected on the roofcurb
- the installer can build up the duct-connections according the the roofcurb drawings while the roofcurb is in delivery, thus saving time
- he can then start to work immediately on the building while the rooftop is in delivery to save time

- from a single friendly controller, the user can program all units (scheduling, setpoints).
- the time override as well as the local setpoint adjustment functions give extra-flexibility to the system. When the user wants to get out of the regular scheduling or setpoint, a local sensor can be used to give extra occupied time or adjust the setpoint. Flexibility!
- when an alarm is detected by the Tracker, first a red LED is blinking, second a message is displayed on the screen.
- Smart start: the Tracker will integrate the previous start-up and define the best time to start the system up so that the setpoint is reached at the begining of the occupied period. The right temperature at the right time.
- security! There is a reading mode available for everyone and a writing mode available with a password only.
- the Tracker can be connected to a computer with the regular Windows package for advanced setup and control (temp curves etc..). It can also be controlled remotely via modem or send alarm message on a remote computer or printer.
