USER MANUAL AWC APPLIED ENERGY

Xpelair AWC Fan Controller mu > instructions are for the Installation and Operatior AWC Fan Controller only. For Fan Installation-andOpet to literature provided with appropriai General Information De: riptio This appliance is designed to control the operation of Xpelair NWAN Whispair fan range. It is designed to minimise the temperature differential between high and low levels in large buïldings. The unit is supplied with two temperature sensors and can be used to operate up to ten NWAN celing sweep fans. The AWC can be operated in either automatic: or manual modes. IN AUTOMATIC MODE: + Ifthe control knob is set in the fully anti- clockwise position, minimum fan speed occurs when the difference in high and low level temperatures is 8°C or less: maximum speed occurs when the difference is 6°C or more. If the control knob is set in the fully clockwise position, minimum fan speed occurs when the difference in high and low level temperatures is 10°C or less: maximum speed occurs when the difference is 18°C or more. To reduce the temperature difference at which the fan speed wil vary, turn the control knob anticlockwise. Increase by tuning clockwise! IN MANUAL MODE: + To reduce the fan speed, turn the knob anticlockwise. To increase the fan speed, tum it clockwise. IN AUTOMATIC AND MANUAL MODES: +_The fan comes on automatically at full speed for the first 10 seconds before reverting to the speed selected. +_ The AWC can be either surface or recess mounted using the metal wall box supplied. These installation instructions are for the installation of the controller when used in combination with Xpelair supplied fans. The controller must be installed to fixed wiring. Ensure the Main Electrical Supply matches the rating shown on the controller casing. THIS APPLIANCE MUST BE EARTHED! All installation must be supervised by a qualified electrician. Installation and wiring must conform to current IEE wiring regulations (UK), or local appropriate regulations (other countries). If you have any queries either before, during or after the installation of the controller, please do not hesitate to contact the UK Xpelair hotline (number on back page). Customers outside UK: contact your local Xpelair distributor.

If wiring to an existing installation isolate mains supply and remove applicable tuses prior to any electrical procedure. If the fan is already installed.

1. Ensure the power supply is isolated.

2. Disconnect the mains connections from the

fan's terminal socket or from the terminal block.

3. Remove the existing wiring and make it safe.

If the fan is not already installed.

2. Mount the fans in accordance with the

instructions supplied.

8. Route the four core cable from the controller

position to each fan.

4. Route the three core cable from controller

position to the isolator position. Mounting the Controller Remove the Cover and Mounting Frame. . Detach the Fascia from the Mounting Frame by removing the screw covers and two screws (Refer to Fig. 2a & b)

2. Detach mounting Frame from the Wall Box by

removing the two screws (Refer to Fig. 20). Lift the Wall Box away from the Plastic Surround.

4. Check that the electrical rating shown inside

the controller matches the power suppl. Disconnect the earth wire from the Wall Box.

6. Make cable entry holes in the plastic and

metal boxes by removing suitable knockouts (Refer to Fig. 1). founting the Wall Bo: Eye protection must be worn during all drilling and chiselling operations. Check there are no buried Pipes or Cables in the wall or obstructions on the outside e.g. Electricity, Gas, Water. If surface mounting Insert suitable glands into the knockouts.

2. Feed both cables through the glands.

3. Fix the Wall Box and Plastic Surround to the

wall, using the mounting holes provided.

4. Re-connect the earth lead to the Wall Box.

1. Make a hole in the wall big enough to take

2. Insert suitable glands into the knockouts.

8. Feed both cables through these glands.

4. Fix the Wall Box to the wall. Ensure that the

flange of the mounting frame its flush to the finished surface of the wall (Refer diagram F3

5. Re-connect the earth lead to the Wall Box.

Mounting the Sensors Using the two clips supplied, mount the temperature sensors horizontally, without touching the walls or celing. + Mount the sensor with the 10m cable in the high level position. + Mount the sensor with the 1m cable in the low level position suitably protected Install the cables in closed conduits, leaving the other ends ready to wire into the controller. Wire the Controller electrical connections . Mount the Isolation Switch in accordance with the manufacturers instructions. Wire the Controller to the Isolation Switch and to the Fan as shown in the appropriate diagram F1. Connect the sensor cables to the high and low sensor terminals. Connect any remaining fans in parallel Refit Mounting Frame to Metal Wall Box. Refit the Fascia to the Mounting Frame. Refit the Screw Covers.
