OVERVIEW Enhanced Commercial Controls RenewAire energy recovery ventilators use static-plate, enthalpy-core heat exchangers that have no moving parts. During summer months, the hot and humid OA passes by the cooler, drier RA, lowing its temperature and humidity. During winter months, the cold and dry OA passes by the warmer, moister RA, raising its temperature and humidity.
OVERVIEW Enhanced Commercial Controls 1.4 COMBINATION TEMPERATURE AND HUMIDITY SENSORS Humidity transducers are mounted in the OA and RA compartments and provide an output from 0–10VDC that is proportional to 0–100% Relative Humidity.

UNIT CONFIGURATION Enhanced Commercial Controls 4.0 UNIT CONFIGURATION 4.1 CONFIGURE GENERAL SETTING There are several general settings that are need for correct operation of the controller. 4.1.1 Setting the Time and Date It is important to have the correct time and date for alarm time stamps and logging. Set Refresh to YES, It will turn back to NO after changing the display to the current controller time and date.
UNIT CONFIGURATION Enhanced Commercial Controls 4.1.4 Scheduler Enable the scheduler, if desired. If you enable the scheduler, it will have to be set for “ON” for the unit to run along with all other “ON” conditions. Enable the scheduler by setting to YES. Set the schedule for each day.
UNIT OPERATION Enhanced Commercial Controls NOTE: If you choose EV450 you will only see information for the supply fan as both fans are run from one motor. 5.0 UNIT OPERATION AND FAN CONTROL The primary purpose of the ERV unit is to provide 100% OA. The amount of air that it provides is based on the configuration of the supply and exhaust fans and whether the unit is running or not.
UNIT OPERATION Enhanced Commercial Controls The Unit status is shown on the bottom of this screen. More than one of these statuses may be valid at one time UNIT STATUS CONDITIONS STATUS SHOWN MEANING Unit on The unit is on and running.

TROUBLESHOOTING Enhanced Commercial Controls 8.0 ALARMS AND TROUBLESHOOTING If the problem is caused by an alarm, the first step in troubleshooting is to view the Alarm screens. Press the Alarm button on the face of the controller to see all current alarms and what function or component is causing the alarm.
TROUBLESHOOTING Enhanced Commercial Controls An alarm log screen looks like this. If the event is Stop, it shows the time that the alarm went away. If the event is Start, it shows the time that the alarm first occurred. There may be up to 50 entries.
TROUBLESHOOTING Enhanced Commercial Controls The physical connection is made at the controller, it is terminated at J12, located in the upper right corner. There is both a normally open (NO6 to C6) and normally closed (NC6 to C6) option. 8.1.5 Specific Alarms and Their Meaning C.pCO n°...

TROUBLESHOOTING Enhanced Commercial Controls Open both dampers. Enable both fans. For the fan that has the alarm (supply or exhaust), command the fan to run at 35% or so. If you see the flow increase but don’t see the feedback (current switch) to yes, then the problem is with the current switch.
TROUBLESHOOTING Enhanced Commercial Controls 8.3 OTHER COMMON PROBLEMS Listed are some other common problems you may encounter. 8.3.1 Unit Not On If the unit will not run, go to this screen in Unit Status and the bottom line will tell you why. Multiple items may be true.
These parameters include all configuration settings, fan settings, heat/cool settings, and BMS settings. 8.5.1 User Commissioning Settings (Service) NOTE: RenewAire At the end of the I/O Configuration, the user is prompted to save their settings. It is probably highly recommends best to save these values after setting all of the values in the Control Variables as well.
TROUBLESHOOTING Enhanced Commercial Controls If you do the operation correctly, it will say “Operation Done.” To restore user settings, the screen is in Backup and Restore. The steps are: Choose the location: internal or USB Set Confirm to Yes You should see “Operation done.” If the unit does not confirm that the operation was done, the controller may have been older and upgraded in the field.
The process is called “Wipe Retain” for anyone familiar with the Carel controller. Most likely unless directed to you will not use this operation unless you are directed to do so by RenewAire Technical Sales do so by TSS. Support (TSS).
CONTROLLER UPDATES Enhanced Commercial Controls To perform this operation, choose YES on the top line Wipe retain mem. 9.0 ACCESSING FILES FROM AND PERFORMING UPDATES TO THE CONTROLLER The controller has a total of about 92 MB of internal memory. There are several types of files that use the internal 92 MB of mass storage that are available on the controller.
CONTROLLER UPDATES Enhanced Commercial Controls 9.2 ALARMS AND DATA LOGS Two types of files that are exported on demand are logs and alarm lists. They can be exported to the internal memory or the USB drive. The export of the logs will show “In Progress” while exporting. It may take a while depending upon the size.
