First, the wiring for the Macromatic THR-15161-32J time delay relay needs to coincide with the connection diagram that's shown on the relay housing. This unit also has an internal jumper connected to pin 2 for easier wiring. Next, use the time delay is set using the blue knob on the relay. It can be set for anywhere within the time delay range, which in this case is 0.1-10 minutes. Once the voltage is connected the relay energizes along with the start of the time delay. Once the time delay ends, the relay de-energizes for the same length of time. It then switches back and forth between on and off at regular intervals until the voltage is removed.
