If it is outside this range the Common Maker may not work as intended. e A common connection allows the thermostat to operate without batteries or “power stealing” circuits. 2. If the thermostat has power but the Common Maker will not activate the equipment, try reversing the wires e The Common Maker is compatible with all 24VAC in the thermostat cable. heating and cooling systems. Incorrect Correct Electrical Safety Thermostat Thermostat e This product should only be installed by a qualified technician. e Requires a Class 2 transformer providing 23-28VAC. e The total connected load must not exceed 2 amps. e The connected load cannot operate at more than Thermostat Thermostat SOVAC (not designed for direct connection to 1ZOVAC Cable Cable equipment). e Toavoid risk of electrical shock or equipment damage, disconnect power before beginning installation.

Keep the Sender wires as long as possible When the Sender has 24VAC applied to its white wire, it to maximize the distance between the Sender and will energize the relay in the Receiver, and complete the thermostat. Do not install the Sender in insulated walls. circuit between the Receiver red and white wires. In most Receiver Installation installations, this will connect the ‘R’ and ‘W’ terminals on the furnace. The Receiver is the larger component and has purple, Standard Dry-Contact white, black, and red wires. It is installed near the furnace, boiler, air handler, zone valve, or zone controller. It should be placed in the equipment cabinet or a location without exposure to liquids or high temperatures. To Sender Follow the relevant wiring diagram for your system (pages 2-4) and connect the wires accordingly. Additional wiring diagrams may be found at www.fast-stat.com. Testing The Common Maker also supports dry-contact switching. After the Common Maker has been installed, check to see In this configuration, the two ‘T’ terminals are electrically if it is functioning properly by following these steps: isolated from the thermostat transformer. 1.
