  • Page 7: Installation

    Installation Overview Installing the thermostat is a relatively simple process and typically takes from 10 to 30 minutes to complete. You should consider the current outdoor temperature. If unexpected problems occur, you do not want to risk freezing or overheating while you are sorting out the problem.
  • Page 8 Your existing installation is should be similar to this depiction. Thermostat Cable You have a single thermostat cable going between your wall mounted thermostat and the furnace. The cable contains from 2 to 5 wires of different colors. Your BAYweb Thermostat installation is shown below. The Control Module is mounted near the furnace or air conditioner and is wired into the existing thermostat cable.

  • Page 9: Identify Wiring

    Identify Wiring The objective of this step is to identify how your thermostat wiring is connected to your furnace, air conditioner, or heat pump. This will also determine what type of control scheme your system uses. A) Turn off all power to your furnace, air conditioner, or heat pump. CAUTION: Verify that all power has been turned off.
  • Page 10 D) If you do not have a wire attached to terminal “C” or “X”, you will need to use the included power supply to power the thermostat. The power supply plugs into a standard 120VAC outlet and to a connector on the control module. E) The following table shows what terminals are used by the different control methods.

  • Page 11: Install Control Module

    Install Control Module A) Find your thermostat cable where it goes into the furnace, air conditioner, or heat pump. This is the same cable identified in Step 1 and should be the same color and thickness as that cable. CAUTION: There may be other cables of similar color connecting other devices such as a humidifier.
  • Page 12 E) Connect the wiring going to the furnace, air conditioner, or heat pump: Attach the wires in the cable coming from the furnace to the terminals on the RIGHT side of the control module labeled "Furnace/AC". Be sure to match the wire color and terminal designation as identified in Step 1.

  • Page 13: Install Thermostat Keypad

    Install Thermostat Keypad A) Remove the wires from your existing thermostat, taking care that the wires do not fall back into the wall. B) Remove the existing thermostat and any associated mounting hardware. C) Fill in any holes from the previous thermostat mounting and paint the wall if needed. D) Hold the Thermostat Keypad in the desired position and mark the location of the mounting screws.
