Target To identify the control program components that accomplishes a

particular sequence of operation.

Task 1. Find the microblocks in the Media Center control program that

satisfies your section of the sequence of operations.

2. Show the class how the two match.

Example Outside Air Conditions

The controller shall monitor the outside air temperature and humidity

and calculate the outside air enthalpy on a continual basis.

These values shall be made available to the system at all times.

Alarms shall be generated as follows:

Sensor Failure: Sensor reading indicates shorted or disconnected

sensor.

In the event of a sensor failure, an alternate outside air conditions sensor

shall be made available to the system without interruption in sensor

readings.

If an OA Temp Sensor cannot be read, a default value of 65F will be

used.

If an OA Humidity Sensor cannot be read, a default value of 50% will be

used.


Section 1 VAV Terminal Unit

sequence of operation

Run Conditions - Scheduled:

The unit will run according to a user definable time schedule in the

following modes:

Occupied Mode: The unit will maintain

o A 74F (adj.) cooling setpoint

o A 70F (adj.) heating setpoint.

Unoccupied Mode (night setback): The unit will maintain

o A 85F (adj.) cooling setpoint.

o A 55F (adj.) heating setpoint.

Alarms will be provided as follows:

High Zone Temp: If the zone temperature is greater than the

cooling setpoint by a user definable amount (adj.).

Low Zone Temp: If the zone temperature is less than the heating

setpoint by a user definable amount (adj.).

Demand Limiting - Zone Setpoint Optimization:

To lower power consumption, the zone setpoints will automatically relax

when the facility power consumption exceeds definable thresholds. The

amount of relaxation will be individually configurable for each zone. The

zone setpoints will automatically return to their previous settings when

the facility power consumption drops below the thresholds.

Zone Setpoint Adjust:

The occupant will be able to adjust the zone temperature heating and

cooling setpoints at the zone sensor.

Zone Optimal Start:

The unit will use an optimal start algorithm for morning start-up. This

algorithm will minimize the unoccupied warm-up or cool-down period

while still achieving comfort conditions by the start of scheduled occupied

period.

Zone Unoccupied Override:

A timed local override control will allow an occupant to override the

schedule and place the unit into an occupied mode for an adjustable

period of time. At the expiration of this time, control of the unit will

automatically return to the schedule.


Section 2 Reversing Variable Volume Terminal Unit - Flow Control:

The unit will maintain zone setpoints by controlling the airflow through

one of the following:

Occupied:

When zone temperature is greater than its cooling setpoint, the

zone damper will modulate between the minimum occupied

airflow (adj.) and the maximum cooling airflow (adj.) until the

zone is satisfied.

When the zone temperature is between the cooling setpoint and

the heating setpoint, the zone damper will maintain the minimum

required zone ventilation (adj.).

When zone temperature is less than its heating setpoint, the

controller will enable heating to maintain the zone temperature at

its heating setpoint. Additionally, if warm air is available from the

AHU, the zone damper will modulate between the minimum

occupied airflow (adj.) and the maximum heating airflow (adj.)

until the zone is satisfied.

Unoccupied:

When the zone is unoccupied the zone damper will control to its

minimum unoccupied airflow (adj.).

When the zone temperature is greater than its cooling setpoint,

the zone damper will modulate between the minimum unoccupied

airflow (adj.) and the maximum cooling airflow (adj.) until the

zone is satisfied.

When zone temperature is less than its unoccupied heating

setpoint, the controller will enable heating to maintain the zone

temperature at the setpoint. Additionally, if warm air is available

from the AHU, the zone damper will modulate between the

minimum unoccupied airflow (adj.) and the maximum heating

airflow (adj.) until the zone is satisfied.


Edit logic parameters

Target To edit the parameters of control programs to satisfy the demands of the

building.

Task 1. Go to the Media Center's Logic page.

8. Go to the Gym's Logic page.

9. Allow an occupant to change the cooling and heating setpoints by

3.

10. Configure the room sensor to provide 1 hour of override time if an

occupant presses the override button one time. Limit the occupant

to 2 hours of override time.

11. On the Media Center's Logic page, make the following changes:

Send an alarm if the zone temperature is 10 higher than the

cooling setpoint.

Send an alarm if the zone temperature is 6 lower than the

heating setpoint.
