Discuss with the City to provide raid document detailed information regarding thermostat <br />locations, connections, wiring, conduit runs, Ethernet switches, power sources, and all <br />other related parameters before beginning the work, <br />Ensure that proposed thermostat "integrated packages" shall have technical specifications <br />including, but not limited to: <br />o Compatible electrical parameters in terms of voltage, amperage etc, for <br />connection to existing HVAC systems/power sources, <br />o Thermostats/Controllers must be able to communicate through current <br />ADR/OpenADR .messaging protocol for receiving Automated Demand Response <br />(ADR) signal from the utility provider, <br />a During the Anto-DR event, the controller shall be capable of resetting the <br />thermostat coaling set point to S degrees F higher than the occupied cooling set <br />point. <br />o Thermostats sball be preferably baud wired finless approved by the City, <br />o Refer to the below list of preferred manufacturers for "Smart" Thermostat <br />packages .far Auto -DR Implementation: <br />• RCS Technology <br />• Honeywell <br />■ Siemens (preferred) <br />• Or Approved Equal <br />• Make sure that all the thermostats ane connected to the internet and communicating for <br />receiving denand response signals, perform test to ensure functionality, <br />yariable Air Volume (_VAV)Control — Pricing to be provided by Contractor as Option B <br />Contractor is to provide this pricing as incremental cost. In other words, the cost beyond Base <br />Option, <br />The new fan coil units should be `!Trane model, IIFCE or HCFD, with BCM fan motors <br />and multi -fan speed controls, <br />The contractor shall programa the EMS and new fan coil units to reduce fan speed to low <br />when zone space set point is satisfied. <br />Vagi le Chilled water Pumping Control — Pricing to be provided by Contractor as Option C <br />Contractor is to provide this pricing as incremental cost. In other words, the cost beyond Base <br />Option. <br />• Install a new variable speed drive to control the existing chilled water pump motor, <br />• The VSD will be controlled by a new differential pressure sensor installed on the existing <br />chilled water loop and modulate the motor to maintain the desired differential pressure <br />set point. <br />• The VSD shall be wall mounted in an easily accessible and safe area, <br />• The new equipment shrill be commissioned to ensure no reduction in service level, <br />City of Santa Ana RFP 17-056 <br />Paye AW <br />25L-52 <br />
