Of the 2 signs for resistors over, the first one is utilized in the UNITED STATE, while the second is used in Europe. I have constructed a simple OR gate using two HVAC fan relays to control a 120VAC/1.5A booster fan for my home HVAC system. The typical electric cooling fan circuit includes a temperature sensor, a relay, a control module and the fan motor. Fan Control. The electric relay in a furnace is responsible for relaying electrical power to the heating elements and the blower motor inside the furnace cabinet. Using a 24v/110v relay (installed in the booster fan's junction box) run 2-conductor T-stat wire back to your furnace. A relay is just a remotely controlled switch that opens and closes using an electromagnet. Products such as gold or copper, are called conductors, as they easily enable flow of motion (low resistance). Literally, a circuit is the course that enables power to flow. A transformer, usually 24 volts, energizes the contactor which has a coil built into it. Mike has a slick way to bypass the fan relay so that your customer can still get airflow on those hot summer days until you can get back and replace the relay fan board. All of these controls have contacts and a coil inside them. $12.91. You might try lightly tapping on the Air conditioning fan relay to see if the fan will go off? $9.99.
