2APQIIT-AF-SMTSmart Attic Fan Control

IT-AF-SMT Smart Attic Fan Control Installation Guide Overview: This document summarizes introductions for operating hub IT-AF-SMT. The IT-AF-SMT can remotely control the QuietCool Attic Fans of QC Manufacturing Inc at up to three different speeds. Key Specifications: IT-AF-SMT (Hub): Voltage: 120V Frequency: 60Hz Motor load: 1HP, 735W (Max) Warning: - Disconnect power at the circuit breaker before installing or servicing - Use wires rated at least 105 o C – copper only - Installation/wiring must be in accordance with national and local code regulations - Keep the enclosure cover closed at all times when not servicing. - Cover all unused wires with a wire connector FCC Regulations: Supplier’s Declaration of Conformity Unique Identifier: Smart Attic Fan Control/IT-AF-SMT Responsible Party: QC Manufacturing Inc. 26040 Ynez Rd. Temecula CA 92591 Tel:951-325-6340 FCC Compliance Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:(1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Caution: The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. FCC RF Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and any part of your body. Rev 2.0 Page 1 of 2 Fig. 1 Dip Switch for Fan Speed Configuration 1 speed fan: Dial 1 to "ON”; and 2 speed fan: Dial 2 to "ON”; and 3 speed fan: Dial 3 to "ON” White wire ACN Black wire ACL Red wire Low speed wire Yellow wire Medium speed wire Blue wire High speed wire Fig. 2 Connection Wires of IT-AF-SMT Input wires: Black: Line voltage, ACL White: Neutral, ACN Output wires: Red: Low speed Yellow: Medium speed Blue: High speed Once wiring is completed, close the hub cover and tighten the screw. Operation: Power on the Hub: Switch on power to the hub, the Power indicator on the hub will be on, and other three indicators will stay off. Press the “Test” button to change fan speed, the fan will run in the following cycles: 1 speed fan: on -> off -> on -> off, 2 speed fan: high speed -> low speed -> off -> high speed -> low speed -> off, 3 speed fan: high speed -> medium speed -> low speed -> off -> high speed -> medium speed -> low speed -> off. And, the Test indicator will blink as follows: Low speed on: the speed LED will blink once every 2 seconds, Medium speed on: the speed LED will blink twice every 2 seconds, and High speed on: the speed LED will blink three times every 2 seconds. Notes: If the corresponding DIP switch of the fan is configured incorrectly, all the indicators on the hub will keep blinking when the hub is powered on. Please switch off power and re-configure the DIP switch correctly. Then try again. Rev 2.0 Page 2 of 2 Installation: IT-AF-SMT (Hub): (Please switch off main power before wiring. The installation should be done by qualified personnel only) The hub (with a curved bottom) should be attached to the cylindrical fan housing and is wired to the fan motor. Remove the screw that holds down the hub cover and flip it up. Once the cover is open, a three digit dip switch is available for fan speed configuration, as shown in Fig. 1.
