Displayed Alarm Message

Action Required

 

 

Condensate Pump Fail

• Verify that the condensate pump circuit breaker has not been tripped.

 

• Ensure that the wiring between the float switch for the condensate pump and

 

the controller is secure.

 

• Confirm that the condensate removal lines are free of debris and are

 

unobstructed.

 

• Confirm the line voltage at the condensate pump.

 

• Ensure that the condensate float switch is moving freely and does not bind.

 

• Confirm that the condensate pump reservoir is clean and free of debris.

 

• Replace the condensate pump.

 

 

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 start-up.

 

• Verify that the alarm threshold for the humidity of the environmental sensors

 

(return or remote) is set 7 - 10 % above the dehumidify setpoint.

 

• Ensure that the reheat mode is enabled and the Reheat setpoint is 2 degrees

 

less than the cool setpoint.

 

• Ensure that there is a proper vapor barrier within the conditioned space.

 

• Ensure that the dehumidify mode is enabled and working properly.

 

• 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 start-up.

 

• Verify that the alarm threshold for the humidity of the environmental sensors

 

(return or remote) is set 7 - 10 % lower than the humidify setpoint.

 

• 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 decrease the humidifier

 

sensitivity setpoint if required.

 

• Ensure that the humidify mode is not disabled because of an active

 

user-defined input mapped to nonessential lockout.

 

• Check the alarm status and event log for humidifer alarms and perform

 

required actions.

 

 

Env Temperature High

• Check whether the Module is cooling. Look for a temperature differential of

 

8–11°C (15–20°F) between the supply and return 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 start-up.

 

• Verify that the temperature alarm threshold for the environmental (return or

 

remote) sensors is 7 - 10°F above the cool setpoint.

 

• Ensure that the cooling mode is enabled and working properly.

 

• Ensure that the cooling mode is not disabled because of an active customer

 

input mapped to nonessential lockout.

 

• Check the alarm status and event log for cooling failure alarms and perform

 

required actions.
