2. Premium Ventilation2 Review Recommendations for Premium Western Economizer Primary sensor control location Two-stage thermostat & coordination Differential dry-bulb outside air changeover Adequate air flow and exhaust relief Ventilation control Quality Assurance

3. Premium Ventilation3 Desired Sequence Min OSA ventilation during heating Use ventilation before cooling Use full OSA vent with cooling coil Lock out or Change over from ventilation to minimum when OSA too warm

4. Premium Ventilation4 Start with a Western Premium Economizer Upgrade the Economizer module with –DCV capable economizer control module –CO 2 Sensor; Min air set to 0% = leakage Add variable speed fan motor –Full (or near full) speed in heating or cooling –Low (30%) speed in idle mode

5. Premium Ventilation5 Triple the Savings Premium Economizer Savings, plus Fan savings when not heating or cooling Savings during warm-up by reducing ventilation when not occupied Ventilation heating and cooling savings when building not fully occupied No need to set and measure outside air minimum

6. Premium Ventilation6 Regional Savings

7. Premium Ventilation7 New Units or Retrofit Retrofit VSD Options –ICM CC750 –Fan Handler Both use temperature control strategy

8. Premium Ventilation8 Currently Custom Incentives Move towards rebate approach Two contractors have proposals for work New Construction and Replacement market
