Fast Stat 3000 Thermostat Add A Wire 4 Wire Over 2 Wire

FAST-STAT - The Model 3000 is often used to add air conditioning to a heating system. It converts a 2-wire cable into a 4-wire cable (R, W, Y, G). It can also converts a 4-wire cable into a 6-wire cable for 2-stage heating, 2-stage cooling or heat pump conversions.

• Used to add air conditioning to a heating system
• Converts a 2-wire cable into a 4-wire cable (R, W, Y, G)
• Can also convert a 4-wire cable into a 6-wire cable for 2-stage heating, 2-stage cooling or heat pump conversions
• Description: Three Functions Over 1-Wire

How It Works
Output A (GREEN wire) and output B (YELLOW wire) are linked so that when output B is on it will also switch on output A. For typical installations output A (GREEN wire) is used for “G” and output B (YELLOW wire) is used for “Y” so does not create any problems as the fan will be on with the when the air conditioner is running.
Output C (WHITE wire) is independent of outputs A & B. It can be on by itself or at the same time as either or both outputs A or B. It is often used for the “W” function but can be used for other functions as well.


Application Examples
Adding Air Conditioning
A 2-wire thermostat cable can be converted to provide R, G, Y & W using the Model 3000.


Wi-Fi Thermostats
If the thermostat cable has three or more wires, the Model 3000 can be used to add a common or “C” connection at the thermostat. This is achieved by having two or three existing functions share one wire which then frees up a wire that can then become a common wire.
Many Wi-Fi thermostats have a self-configure option in which the thermostat automatically detects the wires connected to it in order to make easier for homeowners to install the thermostat. When using the Model 3000, do a “Reset” then select “Pro Setup” to manually configure the thermostat. There are diodes in the Model 3000 sender that often prevents the thermostat from properly autoconfiguring itself.

Adding an Extra Functions
The Model 3000 can be used to add W2, Y2, G, etc to a thermostat cable. For example the existing “W” wire can become W1, W2 & Y2.


Cable Repairs
If a wire in a cable is broken (open circuit) or shorted to another wire or to ground, the Model 3000 can often be used to replace up to two damaged wires. 


Features

• FAST-STAT wiring extenders electronically add more wires to a control cable.
• Saves significant time and expense as compared to repulling of new cables.
• Causes no damage to walls or ceilings as compared to access holes that are often needed when re-pulling cables.
• The Sender and Receiver communicate over the existing thermostat cable and/or outdoor unit cable.
• Not a wireless system and therefore avoids all the problems that wireless systems may have.
• No batteries required. All FAST-STAT models are powered by the existing 24 volt transformer.
• Compatible with all conventional wiring systems using R, C, W, W2, Y, Y2, G, O/B and other terminals.
• Works with old and new systems. Can be connected to older systems such as thermopile millivolt, standing pilot systems, intermittent pilot controllers, fan centers etc.
• Can be used with oil burners, zone controllers and other systems that require “dry contact switching”.
• Works over long cable lengths – up to 500 ft and more.
• FAST-STAT Wiring Extenders do not produce interference with other electronic devices nor are they affected electronic devices that produce large amounts of interference.
• Many FAST-STAT Wiring Extenders can be used in the same building or complex without interference between units.
• Low power use. Most FAST-STAT models use less than 3 watts of power. 

Benefits

• It adds two wires to a cable. For example, with a 2-wire cable, it can provide R, G, Y, W connections at a thermostat and indoor unit.
• With cables having more than two wires, the additional wires can be directly connected to the thermostat and indoor unit and used for any purpose.
• The Sender has six wires; Power In “R”, Power Out “R”, a Communication wire, Input A, Input B and Input C.
• The Receiver has seven wires; Power In “R”, Power Out “R”, a Communication wire, Output A, Output B, Output C and a Common “C” wire.
