Relay 1: SPDT
NC, NO, COM

Timer Motor Connections: 120VAC to 277VAC.

Relay 2: SPDT
NC2, NO2, COM2

Let’s look at an example hookup where the clock and load connection are 120VAC.

Denitions of Terms:

• COM contact is switched between the NO and the NC contacts. This is not “AC Common”
or neutral.

• Normally-open (NO) contacts connect the circuit when the relay is activated; the circuit is
disconnected when the relay is inactive.

• Normally-closed (NC) contacts disconnect the circuit when the relay is activated; the circuit
is connected when the relay is inactive.

• SPST - Single Pole Single Throw. These have two terminals which can be connected or
disconnected.

• SPDT - Single Pole Double Throw. A common terminal connects to either of two others.

• DPST - Double Pole Single Throw. These have two pairs of terminals. Equivalent to two
SPST switches or relay.

• DPDT - Double Pole Double Throw. Equivalent to two SPDT switches or relay.

Do NOT use this for removal!

For 1/2” knock out place small
blade screw driver as pictured. Tap
lightly to punch “knockout” loose.

The following steps show the two most common connections seen in a residence.

For 3/4” “knockout” rst use screw­driver to punchout 1/2” “knockout”
then use pliers to remove outer ring.

120VAC Setup

Make sure you turn off power at the circuit breaker before touching any wires.

*If you are not comfortable installing this product please contact a certied electrician.

Step 1: Connect the Clock Motor Voltage

Dip switch set
for 120 Volts.

The neutral and hot must be connected to “timer” contacts. The dip switch is set to match the input volt­age. In this case it is set for 120VAC (all switches ON or to the Left).

Step 2: Connect Power to the Relay

Power to the relay common must be made on the connector block. It is not connected internally. Here,
the 120V Hot is tied to the Relay 1 Com input. This common input will be switched between the NC and
NO contacts of the relay. (This is not to be confused with the neutral or “AC Common” line.)
