K. Outside Air Bypass Damper
1. The Outside Air Bypass Damper is normally closed. Upon failure of the Supply fan or
loss of normal power, loss of supply duct pressure or supply duct flow, the Outside Air
Bypass Damper shall open, and the mixed air dampers close.
L. Prefilter Differential Pressure Monitor:
1. The controller shall monitor the differential pressure across the prefilter.
2. Alarms shall be provided as follows:
a. Prefilter Change Required: Prefilter differential pressure exceeds a user definable
limit (adj.).
M. Final Filter Differential Pressure Monitor:
1. The controller shall monitor the differential pressure across the final filter.
2. Alarms shall be provided as follows:
a. Final Filter failure: Final filter differential pressure falls below a user definable
limit (adj.).
b. Final Filter Change Required: Final filter differential pressure exceeds a user
definable limit (adj.).
N. Return Air Temperature:
1. The controller shall monitor the return air temperature.
2. Alarms shall be provided as follows:
a. High Return Air Temp: If the return air temperature is greater than 90°F (adj.).
b. Low Return Air Temp: If the return air temperature is less than 45°F (adj.).
O. Supply Air Temperature:
1. The controller shall monitor the supply air temperature.
2. Alarms shall be provided as follows:
a. High Supply Air Temp: If the supply air temperature is greater than 120°F (adj.).
b. Low Supply Air Temp: If the supply air temperature is less than 45°F (adj.).
P. Environmental Index:
1. When the zone is occupied, the controller will monitor the deviation of the zone
temperature from the heating or cooling setpoint and calculate a 0 - 100% Environmental
Index which gives an indication of how well the zone is maintaining comfort. The
controller will also calculate the percentage of time since occupancy began that the
Environmental Index is 70% or higher. Optionally, a weighting factor can be configured
to adjust the contribution of the zone to the rollup average index based upon the floor
area of the zone, importance of the zone, or other static criteria.
