Outdoor air sensors on trane roof top unit.
I had an all new system installed with a trane xl824 thermostat.
At the center of it all is the complete family of trane sensors featuring wired and wireless models dedicated to providing accurate reliable sensing that is critical to keeping hvac systems running at optimum levels.
Each zone has a vav terminal unit that is controlled by a temperature sensor in the zone.
This system consists of a packaged rooftop air conditioner that serves several individually controlled zones.
Remote sensor says 37 degrees.
With that size trane mounts all the sensors within the unit for quick install and run up check the resistances at the boards disconnect them for each one and follow along with the others units to see if there in range note the pins for the ra sa ma to see there in the right pin on the rumbling check all the fan squirrel cages for anything and give the fan a good spin without the belt and listen for bearing noise spin the motor too to see it is ok.

Trane horizon dedicated outdoor air systems are designed specifically to condition up to 100 of outdoor air year round reduce latent loads enhance the entire building system s comfort and energy efficiency and maintain your building s health.
Water source heat pumps.
Rooftop vav systems rooftop variable air volume vav systems are used to provide comfort in a wide range of building types and climates.
Over half of the buildings in north america rely on trane equipment for total occupant comfort and productivity.
It is designed to be installed directly on the actuator.
Packaged units and split systems.

Communicate with prodigy control system on lennox premium rooftop units non prodigy control lennox or aftermarket equipment with optional network thermostat controller and other building functions with the building controller.
It allows the unit to use outdoor air for cooling provided the ambient air is below a certain temperature and the humidity is below a certain percentage.
Economizer the device is built in or retrofitted to rooftop equipment.
The w7459 is used in conjunction with a honeywell actuator m7415 and sensors to control outdoor andactuator m7415 and sensors to control outdoor and return air dampers free cooling using outside air.
However the outdoor temperature sensor on the thermostat either by local nexia weather or the remote sensor is out of calibration by atleast 8 10 degrees.
