type of controls shall be confirmed with VA before proceeding with complete design of automatic
temperature control system.
The Lessor shall provide complete flow and control diagrams for air, water, glycol, and steam systems and
the sequence of operation for all HVAC systems and sub-systems. The diagrams shall show complete
operating description including starting, interlocks, part load operation, smoke control features, volumetric
controls, alarms, and emergency or power failure associated with operation of HVAC systems.
Temperature //and humidity// controls may be electronic //, electric (small jobs only),// or pneumatic //,
