The purpose of this test is to ensure that the central demand shed sequences have been properly programmed into the DDC system.
E 805.11.1 Test Procedure
The procedure for performing a functional test for automatic demand shed controls shall be in accordance with Section E 805.11.1.1 and Section E 805.11.1.2.
E 805.11.1.1 Construction Inspection
Prior to functional testing, verify and document that the EMCS interface enables activation of the central demand shed controls.
E 805.11.1.2 Functional Testing
The functional testing shall comply with the following steps:
Step 1: Engage the global demand shed system. Verify and document the following:
  1. That the cooling setpoint in noncritical spaces increases by the proper amount.
  2. That the cooling setpoint in critical spaces do not change.
Step 2: Disengage the global demand shed system. Verify and document the following:
  1. That the cooling setpoint in noncritical spaces return to their original values.
  2. That the cooling setpoint in critical spaces do not change.
E 805.11.2 Acceptance Criteria
The control system changes the setpoints of noncritical zones on activation of a single central hardware or software point then restores the initial setpoints where the point is released.
