4.2.4OCCUPIED / UNOCCUPIED MODE SEQUENCE

In heating mode, activation of the Occupancy Override Button will change the Active Heating Setpoint from Unoccupied Heating Setpoint to Occupied Heating Setpoint for a period of two hours. In cooling mode, activation of the Occupancy Override Button will change the Active Cooling Setpoint from Unoccupied Cooling Setpoint to Occupied Cooling Setpoint for two hours.

4.2.5ALARM SEQUENCE

The controller will alarm on the following failures. Modem dial-out is initiated when any of the following alarms occur.

High Space Temperature

When Space Temperature is above High Temperature Alarm Setpoint a critical alarm is logged in the Event List and Output 12, Shelter Alarm, is energized. This is a self clearing alarm.

Low Space Temperature

When Space Temperature is below Low Temperature Alarm Setpoint a critical alarm is logged in the Event List and Output 12, Shelter Alarm, is energized. This is a self clearing alarm.

High Space Humidity

When Space Humidity is above High Humidity Alarm Setpoint a critical alarm is logged in the Event List and Output 12, Shelter Alarm, is energized. This is a self clearing alarm.

Low Space Humidity

When Space Humidity is below Low Humidity Alarm Setpoint a critical alarm is logged in the Event List and Output 12, Shelter Alarm, is energized. This is a self clearing alarm.

Blower Failure Unit #1

If Blower operation is called for the blower airflow sensor is checked. If the airflow sensor does not confirm that there is airflow, Output 7, Unit #1 Blower, is de-energized. After 30 seconds the blower is energized again. If airflow is not sensed, Output 7, Unit #1 Blower, is de-energized.

After another 30 seconds the blower is energized again. If airflow is not sensed, Output 7, Unit #1 Blower, is de-energized and locked out. A critical alarm is logged in the Event List and Output 12, Shelter Alarm, is energized. Lead unit switches to lag unit. The Output Alarm must be cleared to resume operation.
