SECTION 033000 - CAST-IN-PLACE CONCRETE

Sludge Treatment Project Engineered Container Retrieval and Transfer System December 2011
1. The controller shall measure the zone temperature and open the heating coil valve to
maintain its heating setpoint.
2. The heating shall be enabled whenever:
a. Outside air temperature is less than 50°F (adj.).
b. AND the zone temperature is below heating setpoint.
c. AND the fan is on.
E. 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.
