| Operation: Respond to Alarms |
Displayed Alarm Message | Action Required |
|
|
Cooling Coil Coolant Temp | • Check the chilled water supply temperature. |
High | • Verify that the coil fluid coolant temperature high threshold is not set below |
| the normal temperature of your chilled water supply. |
|
|
Cooling Coil Coolant Temp | • Check the chilled water supply temperature. |
Low | • Verify that the coil fluid coolant temperature low threshold is not set above |
| the normal temperature of your chilled water supply. |
|
|
Cooling Coil No Coolant Flow | • Verify the flow from the chilled water supply. |
| • Verify that the chilled water supply isolation valve is open. |
| • Check the operation of the flow switch. |
| • Check the electrical connections to the flow switch. |
|
|
Env Humidity High | • Verify that no supply air is fed directly into the return air stream. |
| • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the humidity in the room to stabilize after |
| • Verify that the alarm threshold for the humidity of the environmental sensors |
| (return or remote) is set above the humidify and dehumidify setpoints. |
| • Check the capacity output of the humidifier, and reduce it if required. |
| • Ensure that there is a proper vapor barrier within the conditioned space. |
| • Ensure that the dehumidify mode is enabled. |
| • Verify that the Module is configured and equipped for the dehumidify mode. |
| • Ensure that the dehumidify mode is not disabled because of an active |
| customer input mapped to nonessential lockout. |
|
|
Env Humidity Low | • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the humidity in the room to stabilize after |
| • Verify that the alarm threshold for the humidity of the environmental sensors |
| (return or remote) is not above the humidify and dehumidify setpoints. |
| • Ensure that there is a proper vapor barrier within the conditioned space. |
| • Verify that the Module is configured and equipped for the humidify mode. |
| • Ensure that the humidify mode is enabled. |
| • Check the capacity output of the humidifier, and increase it if required. |
| • Ensure that the humidify mode is not disabled because of an active user- |
| defined input mapped to nonessential lockout. |
|
|
Env Temperature High | • Check whether the Module is cooling. Look for a temperature differential of |
| |
| temperatures. |
| • Ensure that there is no concentrated heat source in the return air stream of the |
| Module. |
| • Ensure that the alarm delay is not set too low. The delay should be long |
| enough to allow the room temperature to stabilize after |
| • Verify that the temperature alarm threshold for the environmental (return or |
| remote) sensors is above the cool and reheat setpoints. |
| • Ensure that the cooling mode is enabled. |
| • Ensure that the cooling mode is not disabled because of an active customer |
| input mapped to nonessential lockout. |
