TROUBLESHOOTING
If you leave a sensor overwritten, an alarm will occur after 24 hours. All overwritten values are
lost on power cycle and the statuses go back to disabled.
When testing in general, the Sensor Overrides is a handy tool. These allow you to temporarily
override a sensor to see if a function is working correctly. For example, if you want to test you
cooling but it is cool outside, you can override your outdoor sensor to exceed the cool lockout
temperature. This is handier than having to change all of your settings and then set them back.
To override a sensor, first set the value of the sensor and then enable. If you enable before
setting the value, the value shown will be set right away. In this case, it will most likely turn on
your heat.
9.4 TESTING FUNCTIONS IN GENERAL
There are several levels of settings in the controller. Some are set by the factory, and some
are set be users. These parameters include all configuration settings, fan settings, heat/cool
settings, and BMS settings.
9.5.1 User Commissioning Settings (Service)
At the end of the I/O Configuration, the user is prompted to save their settings. It is probably
best to save these values after setting all of the values in the Control Variables as well. This is
password protected as every time you save the settings, the file will overwrite. The file name
is “SERVICE.txt,” and it will be save to either the internal memory location, or the external USB
drive that is attached in front.
To perform this operation, the unit must be OFF.

9.5 RESTORE PARAMETERS (SETTING)
NOTE: RenewAire
highly recommends
that a USB thumb
drive be installed in
the USB port and a system
backup (external) be made
immediately after start up
or commissioning.
If you choose USB and you get “Cannot access disk,” there is something wrong with the
connection or disk.
