The pins 1 and 16 are the pins where we need to give the trigger pulse. Connect pin 4 to 5v pin on Arduino board. Now load the following program into the board.

Thus we have two relays in the HFD27 but both are controlled by the same trigger signal. Which means the arm of the switch is connected between 4 and 6 by default and when a pulse is given to the relay the arm hvd27 from 6 to 8, thus disconnecting 6 and connecting 4 to 8.

The same it true for the pins 13,11 and 9 respectively. Among the three pins 4,6,8 hhfd27 and 6 are normally closed that is 4 is be default connected to 6 and when the triggering signal or pulse is given to pin1 the connection between 4 and 6 is broken.

Connect pin 4 to 5v pin on Arduino board. In the post we will see the basics of using the HFD27 relay using the Arduino uno board. The same it true for the pins 13,11 and 9 respectively.

I have a question and i’m not sure if your still monitering this post but i am using this exact same relay with an uno and i want to use it to controll an Hvac system so my question is 00-5s i am using the 2 leads hfdd27 the hvac system and they need to be connected togather would it only be pin 1 and 16 that are connected to the arduino?

The pins 1 and 16 are the pins where we need to give the trigger pulse. Connect pin 16 and cathode of the LEDs to a common point and connect the common point to the ground pin hhfd27 the Arduino board.
