System controller options
Units are available with factory engineered controls as a "plug and play" package. Therefore, the units are provided
with all components including control components (sensors and actuators), controller, and power wiring. In this
case, the unit commissioning is performed by a Trane qualified engineer.
Trane multipurpose controller
Please refer to the Installation Guide for information regarding the controller.
Central connection module
If Factory Engineered Controls are required but a non-compatible BMS is to be used, a Central Connection Module
can be selected. All the Low Voltage end devices are factory installed on the unit and wired back to a central terminal
strip where connections to the BMS controller can be easily made on site.
Central connection module plus *
If Factory Engineered Controls are required but a non-compatible BMS (Building Management System) is to be used,
a Central Connection Module Plus can be selected. This includes all the standard CCM features with the addition
of Power Wiring, A Starter Panel and the installation of a Free-Issued Controller compatible with the BMS is to be
installed. If a different control is installed, please refer to its user guide or manual.
Shipping
The controls enclosure will normally be factory fitted on the fan section of the air handling unit. Please check the
condition of the enclosure on unloading on site. Also check that all factory-mounted controls fitted inside the unit in
the locations indicated in the control sales order are intact and that all loose control items to be supplied with the
unit are present.
Installation
The unit will need to be sited so that there is adequate access to the control panel for commissioning and
maintenance purposes. The minimum clearance is 1 meter wide and 2 meters high. The following site wiring will be
required:
• Mains incoming supply.
• Outgoing supply to other power devices installed.
• External loose items of control.
• Reconnection of wiring inside the unit if the system was delivered in sections. If internal wiring to motors, electric
heaters, etc. was not factory wired, during installation ensure power wiring is not run too close to the existing
control wiring so as not to impair the electromagnetic immunity of the controller.
* Available in selected countries only.
Loose control items
The following components are supplied with the unit but must be mounted and wired on site:
Heating and cooling valves
Each actuator is supplied with a flying lead which needs to be connected on site to a connection box fitted on
the unit.
For outdoor installations, please provide proper protective cover for the valves. If possible, the control valves
should be mounted indoors to maximize the service life. Refer to the data sheet for specific Valve/Actuator project
information.
Room temperature sensor
The room temperature sensor should be wall mounted at a height of approximately 1.5 m inside the occupied space
of average zone temperature. Do not mount the sensor near a heat source, door, direct sunlight or in the supply air
stream. It requires a single pair of screened cables.
Return air temperature sensor
The return air temperature sensor should be mounted in the common return air duct, ahead of the fan, so as to sense
average return air temperature. It requires a single pair of screened cables. When possible, the return air temperature
sensor should be fitted onto the return air inlet.
