Discuss with the City to provide and 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 />C 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 />o During the Auto -DR event, the controller shall be capable of resetting the <br />thermostat cooling set point to 5 degrees F higher than the occupied cooling set <br />point. <br />o Thermostats shall be preferably hard wired unless approved by the City. <br />o Refer to the below list of preferred manufacturers for "Smart' Thermostat <br />packages for Auto -DR implementation: <br />■ RCS Technology <br />Honeywell <br />■ Siemens (preferred) <br />■ Or Approved Equal <br />Make sure that all the thermostats are connected to the internet and communicating for <br />receiving demand response signals, perform test to ensure functionality. <br />Variable Air Volume (VAV) Control — Pricing to o 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, HFCE or HCFD, with ECM fan motors <br />and multi -fan speed controls. <br />• The contractor shall program the EMS and new fan coil units to reduce fan speed to low <br />when zone space set point is satisfied. <br />Variable Chilled Water Pmnping 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 shall be commissioned to ensure no reduction in service level. <br />City of Santa Ana RFP 17-056 <br />2� a 46 <br />
