CONTROL SOLUTIONS FOR BUS HVAC

Total control, at your finger-tips

Different applications need different control solutions, and Thermo King’s CANAIRE®, ClimaAIRE™ and FrontAIRE™ controllers have been developed to meet those needs. Thousands of hours of real-life testing ensure that the controllers are not only high-performing but also durable under the toughest of conditions.

Thermo King’s range of bus HVAC controllers allows the operator to easily and accurately control the climate in his vehicle and ensure the comfort of his passengers, independent of outside conditions.

Easy to read displays present just enough information to monitor temperature set-point and system parameters. Touch buttons and analogue dials offer an intuitive interface for fine tuning of cooling, heating and ventilation.

Diagnostic features are built-in to reduce maintenance and repair costs.

Each bus is different in terms of structure, ambient conditions, operator and passenger needs. Thermo King not only has a wide portfolio of different driver panels but also the expertise to customize the software for most streamlined HVAC functionality in a bus fleet.

CANAIRE®

Rely on the most sophisticated controller in the industry

The CANAIRE® is flexible, modular and expandable HVAC control system. It can be used with the unit only, or expanded to include floor heating, driver’s area and auxiliary pre-heater. All these are controlled from one easy-to-use, intuitive HMI (human machine interface) panel. There are three HMI options to choose from in the CANAIRE® range to suit the specific needs of an installation. The controller uses CAN (Controller Area Network) to communicate with the I/O modules for the expanded functions as well as with the vehicle if required.

• • Driver panel available also in IP54 version
  
• • One integrated driver’s panel for management of driver and saloon areas
  
• • Expandable with up to three main modules to control different zones (e.g. articulated bus, double-decker)
  
• • Easy to read, easy to understand graphic LCD display
  
• • Ambient and two set-point temperature displays for driver and saloon
  
• • Fuel saving features including screw compressor unloader
  
• • Choice of automatic or manual control of temperatures, blower speeds and fresh/recycled air
  
• • Two independently configurable CAN ports => CAN gateway function of the Main control module for safe interfacing between Thermo King HVAC and the on-board bus system ( ISO11898 and/or SAE J1939)
  
• • Real time clock built-into driver’s panel
  
• • Diagnostic tool directly connected via CAN
  

FrontAIRE II™

FrontAIRE II™ is an innovative system offering either automatic or manual climate control of the driver’s cab and of floor heating in the passenger area. Bus drivers can choose to cool, heat, ventilate or pre-heat their compartment and enjoy the ultimate in comfort.

• • Four digit display
  
• • Auto/manual operation: cooling, heating, ventilation, pre-heating
  
• • Easy to read, easy to understand display with automatic brightness
  
• • Stepless control of blower speed, 2 flaps and 2 water valves
  
• • Defrost and smog functions
  
• • Easy installation with standard ISO car radio bracket
  
• • Universal controller for Thermo King Front Box
  
• • Operation modes:
  
• • Stand-alone HVAC front box with condenser
  
• • Dependent on compressor of main HVAC unit
  
• • Real time clock and pre-heater timer
  
• • Compressor and freeze protection
  
• • Alarm mode display and hour meter
  
• • Diagnostics and communication through PC (RS 232 port)

ClimaAIRE I D™

The ClimAIRE I D eliminates the driver interaction and interference with the HVAC system, allowing uniform fleet operation conditions. The controller allows the set point to be predetermined and fixed throughout the operation.

100% fresh air can be selected where appropriate and there is a choice of four operating modes: ventilation, cool, heat and auto. The ClimaAIRE™ is also a sophisticated diagnostic tool, displaying alarms. It can be linked to a PC monitor to display output.

• • Two-digit display with automatic brightness control
  
• • Monitors return air, coil and ambient temperatures via analogue sensors
  
• • Four operating modes: ventilation, cool, heat, auto or reheat
  
• • Fully automatic system with blower and fresh air damper control
  
• • Full diagnostic functions and PC monitor output
  
• • Directly interchangeable with previous model:
  same functions, same mounting slot
