Overview

The following document is used to troubleshoot controller alarms. When an i-Controller alarm exists, you can refer to this

document to understand the condition.

Clogged Filter Notice

The clogged filter notice is generated when the filters in the unit become blocked and possibly need to be replaced. When

a clogged filter notice is generated, “NOTICE” will be displayed next to “Clogged Filt Status” on the Alarms screen.

This notice is generated by a switch that senses a pressure drop across the filter bank and cooling coil. The sensor’s range

of adjustment is 0.17 to 5.0 in. W.C. with contact closure on rise. The switch is mounted in the fan compartment with

terminal connections in the low voltage control section. Normally open dry contacts are provided for clogged filter

indication. This advisory will only be generated during OCCUPIED hours to prevent nuisance alarms during UNOCCUPIED.

CO2Notice (if equipped)

The CO2notice is generated when the CO2level in the space is too high. When a high CO2level is detected, “Hi LvL” will be

displayed next to “CO2 Level Status” on the Alarms screen.

This notice is generated when the CO2sensor, located in the space or return air stream, exceeds the specified ppm limit,

typically 1,000 ppm. The notice will cause the outside air damper (OAD) to open an additional maximum specified

percentage, set to 15% by default. Once the CO2level in the space is lowered, the unit will resume regular operation.

CO2 level

higher than

set point?

Verify unit operation

(seedescription above)

Yes

• Compare the sensor reading with that of the

hand-held meter to ensure its accuracy

• Verify that the sensor dip switches and/or

jumpers are set up correctly

• Verify that the correct sensor was installed (4

wire vs. 3 wire)

• Verify the notice input points on the board or

controller

• Verify that program is set for the correct scale

and type of sensor

Compressor High Discharge Trip Alarm

The high discharge trip is generated when a high discharge pressure condition is present and compressor proof fails. When

a high discharge trip alarm is generated, “ALARM” will be displayed next to “COMP High Dis Trip” on the Alarms screen.

When the discharge pressure decreases, and the compressor proof is made, the compressor high discharge trip will

automatically reset.

Compressor Proof Alarm

The compressor proof alarm is generated when a specific compressor is not running when enabled by the controller. If a

digital compressor is at 50% capacity and the discharge pressure minus suction pressure is less than 20psi, a compressor

proof alarm will be generated. If a fixed compressor is on and the discharge pressure minus suction pressure is less than

40psi a compressor proof alarm will be generated. When a compressor proof failure is detected, “No Comp Proof” will be

displayed next to “COMP” on the Alarms screen.

When a successful proof signal is received by the controller, the compressor proof alarm will automatically reset.

Drain Pan Overflow Alarm

The drain pan overflow alarm is generated when the drain pan float switch detects an elevated level of water in the

condensate drain pan. When an overflow alarm is generated, “ALARM” will be displayed next to “Overflow Status” on the

Alarms screen.

The normally closed float switch, located in the condensate drain pan and will open if the water level if too high. After a 30

second delay, the Flōunit will shut down to prevent the water from overflowing out of the drain pan.

When the water level in the drain pan decreases and the float switch input closes, the drain pan overflow alarm will

automatically reset.

Fan Fail Alarm

The fan fail alarm is generated when a fan fails to start for more than 10-minutes when enabled by the controller. When a

fan fail alarm is generated, “ALARM” will be displayed next to “Fan Status” on the Alarms screen.

This alarm is generated when the digital airflow switch, located in the fan cabinet, detects a loss of airflow and switches

from normally open to closed. The Fan Fail alarm may also be generated during a Phase Loss alarm.

When a fan fail alarm occurs, the Flōunit will be shut down. The fan fail alarm must be manually reset using the i-Controller

Visograph display.

Wait 10 minutes

If the airflow switch does not close

within 10 minutes, the unit will re-alarm

High Discharge Pressure Alarm

The high discharge pressure alarm is generated when the discharge pressure increases above 500psi for 5-minutes while a

compressor is enabled throughout dehumidification or cooling mode. In the event of controller failure, a mechanical cut-

out will occur at 600 psi. When a high discharge pressure alarm is generated, “High Dis Press”will be displayed next to
