TROUBLESHOOTING

9.3 OTHER COMMON PROBLEMS

Listed are some other common problems you may encounter.

9.3.1 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. Possible messages and their meaning:

Unit On: Unit is running

Off by Alarm: A serious alarm is present; usually a fan alarm or supply temp alarm.

Off by BMS: The BMS has set Enable BMS Control to yes and is not sending an On command.

Off by DI: The terminals 17 and 18 need to be closed or jumped.

Off by Keyboard: The menu screen

Unit On/Off

is set to off.

Off by CO2 Level: the CO@ level is too low for the unit to run (special feature).

Exhaust Fan Only Mode: The terminals 18 and 19 are closed indicating single fan mode. The

setting for which fan will run is in

I/O Configuration

Supply Fan Only Mode: The terminals 18 and 19 are closed indicating single fan mode. The

setting for which fan will run is in

I/O Configuration

BMS Cool Lockout: This means that

BMS Heat/Cool Mode?

Is set to Yes in

General Settings

and the current mode is heat.

BMS Heat Lockout: This means that

BMS Heat/Cool Mode?

Is set to Yes in

General Settings

and the current mode is cool.

In Device Test: Mode in

Test End Devices

is enabled. Cycle power to get it out of this mode.

Input Overwritten: There is a sensor that is overwritten in Sensor Overrides. This occurs after

24 hours as a reminder.

Unit Off by CO2 Level, Frost Control Active.

9.3.2 Sensor Reading #### or Has Extreme Value
This normally means that the sensor is not connected, or it has faulty wiring.

9.3.3 BMS Loss of Comm after Param Change or Restore
Most BMS setting changes require a power cycle. This applies to a parameter restore, which is
basically the same thing.

9.3.4 Can Not See Device via IP Connection
If you are connected locally with a PC:

Make sure your PC is on the same subnet but not the exact same IP address. The last octet

has to differ.

If you have just changed the IP address, make sure you said “update” on that screen and

cycle power.

Make sure the cable “snaps in” on both sides.

Microsoft Edge browser does not work as well. Use Chrome, if possible.

Make sure you don’t have anything in the USB connection in the front of the controller.

If you are connected remotely, check all of the above but also note that the connection has to be
on the same subnet. An IP tunnel may also work.
