FAST-STAT Model 5000 HVAC Wiring Extender - Adds x3 Wires + Common 'C' Connection

FAST-STAT Model 5000 HVAC Wiring Extender - Adds x3 Wires + Common 'C' Connection.

Product Overview:

  • The Model 5000 provides 3 additional control wires and a common connection ‘C’ between a thermostat and indoor unit.
  • Works with all Wifi Thermostats, including EcoBee, Nest, and Lyric.
  • Can not be used to extend the wiring between an indoor and outdoor unit.
  • Compatible with most 24VAC heating and cooling systems.
  • Requires a minimum of a 2-wire thermostat cable.

    Electrical Safety:

    • This product should only be installed by a qualified technician.
    • Requires a Class 2 transformer providing 23-28VAC.
    • The total connected load must not exceed 2 amps.
    • The connected load cannot operate at more than 30VAC (not designed for direct connection to 120VAC equipment).
    • To avoid risk of electrical shock or equipment damage, disconnect power before beginning installation.

    Sender Installation:

    The Sender is the smaller component and is installed inside the wall behind the thermostat.

    • Remove the thermostat from the wall.
    • If the hole where the thermostat cable wires come through is not big enough to fit the Sender, enlarge it.
    • Place the Sender in the wall and connect the wires to the sub-base according to the wiring diagram (pages 3-4). The Sender will hang by its wires and does not require any mounting.
    • Install the thermostat on the wall.

    Note: The Sender will produce a small amount of heat while operating. Install the Sender at least 8” (20cm) away from the thermostat. Do not install the Sender in insulated walls.

    Receiver Installation:

    The Receiver is the larger component and is installed inside the cabinet of the indoor unit. If there is no space inside the cabinet, the Receiver may be placed in any location without exposure to high temperatures or water.

    Connect the Receiver according to the wiring diagram for the system (pages 3-4).

    If the installation only has single stage heat, only the Sender and Receiver’s white wire will be used. The blue wire from the Sender and Receiver should be taped back.

    Some installations may require the Receiver voltage to be adjusted. See ‘Setting the Receiver Voltage’ for more information.

    Setting the Receiver Voltage:

    The FAST-STAT Model 5000 is factory set to be compatible with most thermostats. Differences in transformer voltage and thermostat power consumption may require the Receiver to be adjusted. The adjuster is located on the side of the case and can be turned to increase or decrease the Receiver voltage.

    The voltage (DC) of the Receiver is measured between the Receiver’s orange wire and transformer Common. It is factory set for approximately 0.30V (with a 24VAC transformer) while disconnected from the thermostat. When connected to a typical thermostat in standby, the voltage should be between 0.40V to 0.50V.

    Check each function on the thermostat (G, Y, W1, W2) to see if the connected equipment turns on and off correctly.

    If the equipment does not turn on when called, the Receiver voltage may be too low. With the thermostat calling for any function, increase the Receiver voltage until the equipment activates. Set the voltage to 0.05V over the minimum voltage the equipment activates at.

    If the equipment does not turn off when the thermostat stops calling, the Receiver voltage is too high. With the thermostat not calling for any function, decrease the Receiver voltage until the equipment turns off.

    After the Receiver voltage has been set, check that all equipment turns on and off correctly. The orange wire should be taped back as it is no longer needed.

    Operation:

    The Model 5000 has two channels, green and yellow, and white and blue.

    Applying 24VAC to the Sender’s green wire will output 24VAC on the Receiver’s green wire.

    Applying 24VAC to the Sender’s green and yellow wires will output 24VAC on the Receiver’s green and yellow wires.

    Applying 24VAC to the Sender’s white wire will output 24VAC on the Receiver’s white wire.

    Applying 24VAC to the Sender’s white and blue wires will output 24VAC on the Receiver’s white and blue wires.

    When 24VAC is applied to the Sender’s white or blue wires, the yellow and green wires at the Receiver will not output 24VAC regardless of whether or not they are being called.

    Trouble Shooting:

    1. Measure the transformer voltage to check if it drops below 23VAC while in use. The Model 5000 may not function properly outside of the 23-28VAC range and the transformer may need to be replaced.
    2. If applying 24VAC to ‘G’ on the Sender activates ‘W1’ on the Receiver, or vice versa, then the two wires that connect the Sender and Receiver are crossed. Disconnect the thermostat cable and swap the connections.
    3. At the thermostat, jumper ‘R’ to ‘G’ to activate the fan. Jumper ‘R’, ‘G’, and ‘Y’ to activate the fan and condenser. Jumper ‘R’ to ‘W1’ to activate first stage heat. Jumper ‘R’, ‘W1’, and ‘W2’ to activate second stage heat. If all functions work correctly when jumpered, then the thermostat may not be configured properly. If no functions operate there may be a break in the thermostat cable.
    4. If the Receiver is set to the highest voltage possible and still does not activate the equipment when called, then the power consumption of the thermostat may be too low. Please contact FAST-STAT technical support line at 1-800-775-4750.
