Innovair Duotec Initial Setup Guide
A: Auxiliary Heat Kw/CFM (Violet Wire) Select the capacity size of the electric heat strip is you are going to be installing one following the model of your air handler. Use: (Table 1) B: Outdoor Unit Size (Blue Wire) Select the outdoor unit size that the indoor air handler will be working with following the model of your air handler. Use: (Table 2) C: System Type AC/HP (Orange Wire) Select one from the three types of systems. Use: (Table 3) D: AC/HP CFM Adjust (Black Wire) This selection basically selects: Medium, Low, or High Airflow. E: ON/OFF Delay (White Wire) This selection basically selects the desired time delay. Note: Delay selections are active in cooling and heat pump heating modes only. Auxiliary heating modes have a one (1) minute off delay and zero (0) on delay programmed into the ECM motor that cannot be overridden. F: Continuous Fan (Yellow Wire) Select the desired continuous fan speed when thermostat is set on continuous fan operation by using the yellow jumper wire. Note: If installed with a two-stage outdoor unit, do not select HI speed continuous fan. If HI is selected, low stage compression (low-speed cooling) will also run HI fan speed possibly resulting in insufficient dehumidification.
