Slide 1: Welcome to the fourth AdaptAire webinar
Welcome to the fourth AdaptAire webinar webinar. 1
Slide 2: This webinar is the fourth in The AdaptAire Basics series
This webinar is the fourth in The AdaptAire Basics series. series The AdaptAire Basics webinars are designed as a series of short presentations lasting 20 – 30 minutes. Each webinar will cover a different topic so you should schedule time to attend the remaining four. 2
Slide 3: Format of each webinar
The format for each webinar will be a short review of the previous webinar webinar, followed by the scheduled presentation, followed by a recap. We will end with time for questions. 3
Slide 4: Recap of the 3rd webinar
Let’s take a moment to recap what we learned in the 3rd webinar. We learned the MRT system is the most basic room temperature control system and the remote user interface has 1 or 2 pots that control the unit and damper operation. We discussed the wiring for the remote and saw the plugs on the back
Slide 5: MRT control system limitations recap
I mentioned the MRT control system cannot do scheduling, change factory setpoint, or reset faults. You also heard that there is limited BAS control. Finally you learned that the unit can pretty much be configured to do most anything with a few minor modifications. 5
Slide 6: Introduction to the MRT-Pro
The MRT user interface is the basic modulating room temperature control, the next Applied Air offering for modulating room temperature interface is the MRT-Pro. In the next few slides you’ll see how the MRT-Pro looks. You’ll see how the MRT-Pro work. You’ll get a taste for what the MRT-Pro can do. A
Slide 7: MRT-Pro remote user interface
Pictured is the basic MRT-Pro remote user interface. It mounts on a 1 gang electrical box and can be mounted up to 500’ away from the unit. This remote is used for all of the different Applied Air products. Each MRT-Pro remote user interface will have an LCD display and 4 buttons.; they are Manual O
Slide 8: Manual On button and runtime operation
Unlike the MRT the MRT-Pro has no potentiometer used to start the unit or set the desired room temperature setpoint. To start the fan the user need only push the Manual On button. The Manual On button is similar to a twist timer or the override button found on many timeclocks. Each time the Manual O
Slide 9: Info button and setpoints
When the Info button is pressed, the first thing that is displayed is the Outside Air temperature. A second press displays the remaining runtime. Another push and the Heating Setpoint is displayed. The occupied setpoint is 65°F and the unoccupied setpoint is 55°F. 55°F One more push shows the coolin
Slide 10: Back of the MRT-Pro remote user interface
The back of the MRT-Pro remote user interface has one 4 wire connector. The interface can be mounted up to 500’ from the unit. The remote interface is more than just a plain sensor. Under the cover is a thermistor sensing element. Located in the bottom of the sensor is a communication port for conne
Slide 11: MRT-Pro AdaptAire system basics
As you’ve seen so far, the MRT-Pro AdaptAire system is fairly basic. It is similar yet simpler than a programmable home thermostat. It was designed to provide the user with a bit more flexibility than the MRT user interface. The MRT-Pro user interface starts and stops the unit via the Manual On butt
Slide 12: What else does the MRT-Pro do?
What else does the MRT–Pro do? The MRT–Pro control also provides freeze protection by shutting off the unit if the discharge temperature drops below 45°F for three continuous minutes. The MRT–Pro has 2 energy savings functions that can save the customer money when heating and cooling are not require
Slide 13: What the MRT-Pro controls cannot do
We’ve just seen what the AdaptAire MRT-Pro controls can do. Now let’s look at what they cannot do. The MRT-Pro controls do not and cannot have a time clock function because the unit must be started with the Manual On button. Except for the room temperature setpoints the MRT-Pro controls do not allow
Slide 14: Adding items to overcome the limitations
You’ve just heard about the limitations of the AdaptAire MRT–Pro controls, but by adding a few other items to the controls it is possible to do some of those previously mentioned CAN’T DO items. Because run time must be entered using the MANUAL button or by scheduling through a BAS, a BAS is the bes
Slide 15: Adding functions not part of MRT-Pro controls
As you see, most any function that is not part of the AdaptAire MRT-Pro controls can be added. If you have an application that doesn’t quite fit the control system, contact your Applied Air application engineer or technical service advisor for assistance. 15
Slide 16: Recap of this webinar
Let’s take a moment to digest everything we’ve discussed so far. We learned the MRT-Pro remote user interface has 4 buttons that allow the user to adjust the room temperature setpoints, start and stop the unit and provide some limited system information. We discussed the wiring for the remote and sa
Slide 17: MRT-Pro limitations and BAS control
I mentioned the MRT-Pro control system cannot do scheduling, change factory setpoints, or reset faults. Finally, you also heard that there is unlimited BAS control. 17
Slide 18: This concludes the fourth AdaptAire webinar
This concludes the fourth AdaptAire webinar webinar. I’ll I ll open the line for some questions questions. 18
