Intermatic Spring Wound Interval Timer
INSTALLATION INSTRUCTIONS
This spring wound timer is designed for easy installation, similar to a light switch, in a standard 2-1/2 inch deep vertically installed junction box. It can replace a standard single pole, 3-way, or double pole single throw wall switch. The timer automatically turns off lights, fans, air conditioners, and other loads after a preset timing period.
CAUTION: This timer should not be used in precision timing applications where inaccurate timing could have dangerous consequences (e.g., sun lamps, saunas).
INSTALLATION
The type of wall switch plate required depends on your timer model:
- Models with FF prefix (metal time dial wall switch plate): See Illustration A.
- Models with FD prefix (small ivory, white, or colored plastic time dial plate): You will need to supply a standard toggle or decorator design wall switch plate. See Illustration B1 or B2.
Steps for Installation:
- Ensure electrical power is turned off at the breaker or fuse panel for safety.
- Remove the existing wall plate and disconnect the switch from the vertically installed junction box.
- Strip the end of wires to 1/2 inch, as indicated by the strip gauge on the back of the timer.

Step 4: Insert the stripped ends of wires under the pressure plate of the terminal screws on the side of the timer. Screw down tightly. (Terminal screws are provided in a plastic bag).
Diagram Description: Illustration A
An exploded view shows the timer unit, a metal time dial plate with an "OFF" marking, a nut, and a threaded extension on the timer. It illustrates how the metal plate slips over the threaded extension and is secured by the nut. The timer connects to a standard 2 1/2 inch deep junction box. Terminal screws are shown with pressure plates for wire insertion.
Step 5: Insert the wired timer into a 2-1/2 inch deep standard wall junction box with the "TOP" indicator (on the front of the timer) in the proper position. Fasten the timer to the junction box using the two long flat head screws provided.
Step 6: Slip the metal time dial plate over the threaded extension. Ensure the "OFF" mark of the time dial plate is on top, as marked on the front of the timer.
Step 7: Fasten the metal dial plate securely to the timer with the stamped nut provided.
FD Models Only (Illustrations B1 and B2)
Step 8: Place the standard toggle or decorator plate on the timer. Do not over-tighten.
Note for FD Models:
- For standard toggle switch plates (Illustration B1): The two screws provided with the switch plate are not necessary for attachment. The nut provided with the timer will securely hold the switch plate. If screws are used, they must be self-tapped into the timer body, requiring gentle inward pressure while turning to self-tap.
- For decorator style wall switch plates (Illustration B2): Threaded holes are provided in the metal tabs at the opposite ends of the timer. Fasten the decorator style plate using the two screws provided with the switch plate, but do not over-tighten.
Diagram Description: Illustration B1
An exploded view shows the timer unit, a standard toggle switch plate (single or multi-gang, not included), a plastic time dial plate with an "OFF" marking, a knob, and a nut. It shows the plastic dial plate fitting over the timer's threaded extension and being secured by the nut. The timer mounts into a standard 2 1/2 inch deep junction box. Screws for the switch plate are noted as not required.
Diagram Description: Illustration B2
An exploded view shows the timer unit, a decorator-style switch plate (single or multi-gang, not included), a plastic time dial plate with an "OFF" marking, a knob, and a nut. It highlights that switch plate screws (supplied with the switch plate) are required and thread into the timer's metal tabs. The plastic dial plate fits over the timer's threaded extension and is secured by the nut.
Step 9: Slip the plastic time dial plate over the threaded extension. Ensure the "OFF" mark of the time dial plate is on top, as marked on the front of the timer. Fasten securely to the timer with the nut provided. DO NOT OVER-TIGHTEN.
Final Installation Steps
Step 10: Push the knob onto the timer shaft so the knob pointer centers on "OFF" on the dial plate. The knob has a "D" shaped hole that matches the "D" shaft on the timer.
Step 11: Restore power.
HOW TO OPERATE YOUR TIMER
FOR AUTOMATIC TIMING OPERATION: Turn the timer clockwise to the desired time. The timer will turn the load "OFF" at the end of the preset timed period. Note that timers (SPDT) wired for reverse action applications will turn the load "ON" at the end of the preset timing period.
TO BYPASS TIMER: (Models with "hold" feature only) Turn counterclockwise to stop. At this position, the timer does not operate, but the switch is "ON" until the knob is manually returned to "OFF".
APPLICATIONS
Intermatic spring wound timers are versatile and can be used for many applications, depending on their pole configurations:
SPST (Single Pole, Single Throw)
Used to break the hot side of any 120 volt load, such as:
- Coffee Pots
- Air Conditioners
- Lighting
- Ventilating Fans
Diagram Description: SPST Wiring
A circuit diagram shows a 120 V.A.C. power source connected to a load through the timer. The timer has terminals labeled LINE, LOAD, and a switch mechanism controlling the circuit.
SPDT (Single Pole, Double Throw)
For applications requiring 3-way switching (two timers or a timer and a 3-way switch) or reverse action applications. Reverse action applications allow a load to be turned "OFF" for a limited time, after which the load will switch back "ON".
Three-way applications are used for controlling a load from two different locations, such as:
- Hallways
- Corridors
- Self-storage Facilities
- Upper Level/Lower Level
Diagram Description: SPDT 3-Way Switching
A circuit diagram illustrates controlling a load from two locations. It shows a power source (120 V.A.C.) connected to a load via two switches, one being the timer and the other a standard 3-way switch. Connections are made via LINE 1 and LINE 2 terminals.
Diagram Description: SPDT Reverse Action Switching
A circuit diagram shows a load controlled by a timer wired for reverse action. The timer is set to turn the load "OFF" for a specified duration, after which it automatically switches the load back "ON".
DPST (Double Pole, Single Throw)
For applications where both sides of a 208, 240, or 277 volt load must be switched. Applications include:
- Large Horse Power Motors
- Pumps
- Indoor Lighting
- Outdoor Lighting
Diagram Description: DPST Wiring
A circuit diagram shows a 240 V.A.C. power source connected to a load through a DPST timer. The timer switches both sides of the load, controlling LINE 1 and LINE 2 connections.
