Installation and Wiring
Proper installation and wiring are crucial for safe and reliable operation of the Intermatic ST01 timer, ensuring optimal performance and longevity of the device.
Safety Precautions
Prior to installation and wiring, always disconnect power at the main breaker or fuse box to prevent electrical shock. Never attempt to install or service the Intermatic ST01 while power is connected; this poses a serious safety hazard.
Ensure all wiring connections adhere to local and national electrical codes. Incorrect wiring can lead to fire or equipment damage. Use appropriately sized wire for the load being controlled, and verify secure connections to prevent loosening over time.
Qualified personnel should perform the installation. If you are unfamiliar with electrical wiring, consult a licensed electrician. Avoid installing the timer in damp or wet locations, and protect it from extreme temperatures. Regularly inspect wiring for damage or wear, replacing as needed.
Always read and understand all instructions before beginning installation. Failure to follow these precautions could result in personal injury or property damage.
Wiring Diagram – Standard Applications
For typical lighting or appliance control, connect the line (hot) wire to the ‘L’ terminal on the Intermatic ST01. The neutral wire connects directly to the load’s neutral connection, bypassing the timer. The load wire connects to the ‘T’ (switched hot) terminal. Ensure proper grounding by connecting the ground wire to the grounding terminal on both the timer and the electrical box.
Voltage compatibility is crucial; verify the ST01 matches your supply voltage. Use wire nuts or terminal blocks for secure connections. A common setup involves controlling a single light fixture, but the ST01 can manage various loads within its specified rating.
Double-check all connections before restoring power. Incorrect wiring can damage the timer or connected devices. Refer to a qualified electrician if unsure about any aspect of the wiring process. Always prioritize safety and adhere to local electrical codes.
Wiring Diagram – Astro Mode
Astro Mode utilizes the ST01’s internal astronomical time clock to automatically adjust on/off times based on sunset and sunrise; Wiring remains largely similar to standard applications: Line (hot) to ‘L’, neutral directly to the load, and the load wire to ‘T’. However, Astro Mode requires accurate location programming within the ST01’s settings.
The timer calculates dusk and dawn times based on your latitude and longitude, eliminating manual adjustments for seasonal changes. Ensure the location settings are correct for optimal performance. This mode is ideal for outdoor lighting, providing illumination when needed most.
Proper grounding is still essential. Verify voltage compatibility and secure all connections. Consult the ST01’s programming section for detailed instructions on setting latitude, longitude, and desired on/off offsets.
Wiring Diagram – Countdown Mode
Countdown Mode allows for timed operation, activating a load for a pre-set duration. Wiring parallels standard setups: connect Line (hot) to ‘L’, Neutral to the load’s neutral, and the load wire to ‘T’. The key difference lies in programming the desired countdown time within the ST01’s interface.
This mode is perfect for temporary applications like pumps, fans, or lights needing a specific runtime. The ST01 initiates the countdown upon receiving a signal, automatically switching off the load once the timer expires. Accurate time setting is crucial for precise operation.
Ensure secure connections and proper grounding; Refer to the ST01’s programming section for detailed instructions on setting the countdown duration. Remember to verify voltage compatibility before connecting any devices.

Setting Up the ST01
Initial setup involves accurate time and date configuration, followed by selecting either Astro or Countdown mode, tailoring the ST01 to your specific scheduling needs.
Initial Power-Up and Time Setting
Upon initial power-up, the Intermatic ST01 will likely display a default time or require immediate setting. Access the time setting function through the unit’s buttons, typically involving a ‘Mode’ or ‘Set’ button to enter the configuration menu.
Navigate through the hours, minutes, and potentially year/month/day using the up and down arrow buttons. Confirm each selection by pressing the ‘Set’ or ‘Enter’ button. Ensure accuracy, as the ST01 relies on precise timekeeping for scheduled events.
Refer to the front panel overview within this manual for specific button locations. Remember that proper time synchronization is crucial for Astro mode functionality, aligning with sunrise and sunset times. Double-check the set time against a reliable time source to guarantee correct operation.
Interia, a Polish portal, emphasizes accurate information, mirroring the ST01’s need for precise time settings for reliable performance.
Programming Astro Mode
Astro Mode automates on/off times based on calculated sunrise and sunset times for your location. Access Astro Mode through the ST01’s menu, typically using the ‘Mode’ button to cycle through options. Once selected, you’ll need to input your latitude and longitude coordinates for accurate calculations.
The ST01 may offer offset adjustments, allowing you to shift on/off times relative to sunrise/sunset. For example, you can set lights to turn on 30 minutes before sunset. Configure these offsets using the arrow buttons and confirm with ‘Set’ or ‘Enter’.
Consider daylight saving time; the ST01 may have an auto-DST setting or require manual adjustment. Interia, like the ST01, adapts to changing conditions – DST being a prime example. Verify settings periodically for optimal performance.
Consult the display and button functions section for navigation details.
Programming Countdown Mode
Countdown Mode allows you to program a specific duration for which the connected device will remain on, after which it automatically switches off. Access this mode via the ST01’s menu system, navigating with the ‘Mode’ and arrow buttons. Select ‘Countdown’ and then input the desired runtime in hours and minutes.
The ST01 typically displays the remaining countdown time. Confirm your settings using the ‘Set’ or ‘Enter’ button. This mode is ideal for temporary applications, like powering a pump for a set period. Remember, like Interia’s constantly updated news feed, the countdown is dynamic.
Some ST01 models may allow for multiple countdown schedules. Review the display and button functions section for specific instructions on managing these schedules. Ensure the countdown duration aligns with your intended use.
Verify the countdown is functioning correctly after initial setup.
Manual Override Function
The Manual Override feature allows you to temporarily bypass the programmed schedule and directly control the connected device; This is useful for immediate activation or deactivation, independent of the timer’s settings. Typically, pressing and holding the ‘Override’ button will toggle the output on or off.
The ST01 display will usually indicate when the override is active, often with a specific icon or message. Like Interia’s immediate news updates, this provides instant control. Note that the override duration can vary; some models revert to the schedule after a set time, while others require manual deactivation.
Consult the display and button functions section for your specific ST01 model’s override behavior. Be mindful of energy consumption when using the override, as it disregards programmed energy-saving settings.
Always return to scheduled operation once the temporary need has passed.

Advanced Features and Settings
