What Is an Intermatic Timer?
An Intermatic timer is an electromechanical or digital device designed to automatically control the on/off cycles of electrical circuits, effectively acting as a programmable switch for various applications like lighting, pumps, and HVAC systems.
Introduction to Intermatic Timers
Intermatic is a leading manufacturer of time switches and energy controls, and their timers have become synonymous with reliability and efficiency in managing electrical loads. These timers offer a convenient and cost-effective way to automate processes, conserve energy, and improve the safety and security of homes and businesses. From simple mechanical timers to sophisticated digital models, Intermatic provides solutions for a wide range of needs.
The Evolution of Intermatic Timers
Initially, Intermatic timers were primarily electromechanical devices relying on gears and a synchronous motor to track time and trigger switches. These mechanical timers were robust and relatively simple to operate. Over time, advancements in technology led to the development of digital timers, which offer greater precision, flexibility, and programmability. Digital timers utilize microprocessors and electronic components to control switching operations, often providing features like multiple on/off schedules, daylight saving time adjustments, and battery backup.
Benefits of Using Intermatic Timers
Intermatic timers offer numerous advantages:
- Energy Savings: Automate lighting and other devices to prevent them from running unnecessarily, reducing energy consumption and lowering utility bills.
- Convenience: Eliminate the need to manually turn devices on and off, providing a hands-free solution for managing electrical loads.
- Security: Simulate occupancy by automatically turning lights on and off, deterring potential intruders.
- Automation: Simplify tasks and processes by automatically controlling electrical devices based on a pre-programmed schedule.
- Precision: Digital timers offer accurate timekeeping and scheduling, ensuring reliable operation.
Types of Intermatic Timers
Intermatic offers a diverse range of timers to suit different applications:
- Mechanical Timers: Simple and reliable timers with a rotating dial and adjustable trippers to set on/off times.
- Digital Timers: Feature a digital display and programmable settings for precise scheduling and advanced features.
- Astronomic Timers: Automatically adjust on/off times based on sunrise and sunset times, eliminating the need for manual adjustments.
- Pool and Spa Timers: Designed specifically for controlling pool pumps, heaters, and lighting, ensuring efficient operation and energy savings.
- In-Wall Timers: Installed directly into a wall switch box, providing a convenient and aesthetically pleasing solution for controlling lighting and other devices.
How Intermatic Timers Work
The fundamental principle behind an Intermatic timer is the control of an electrical circuit. Mechanical timers use a rotating dial with adjustable trippers that physically engage a switch, opening or closing the circuit at predetermined times. Digital timers, on the other hand, use a microprocessor to monitor time and trigger a relay, which acts as the switch.
Here’s a simplified breakdown:
- Time Tracking: The timer continuously tracks time using either a synchronous motor (mechanical) or an internal clock (digital).
- Schedule Comparison: The current time is compared to the programmed on/off schedule.
- Switch Activation: When the current time matches a programmed on/off time, the switch (either mechanical or relay-based) is activated.
- Circuit Control: The switch either opens (turns off) or closes (turns on) the electrical circuit connected to the timer.
Choosing the Right Intermatic Timer
Selecting the appropriate Intermatic timer depends on various factors:
- Application: Consider the specific device or system you want to control (e.g., lighting, pool pump, HVAC).
- Load Requirements: Determine the voltage and amperage of the electrical load to ensure the timer is properly rated.
- Scheduling Needs: Assess the complexity of the scheduling requirements (e.g., number of on/off cycles, daily or weekly schedules).
- Features: Evaluate the desired features, such as astronomic timing, battery backup, and remote control capabilities.
- Installation Location: Consider the location where the timer will be installed and choose a suitable model (e.g., in-wall, surface-mount).
Common Mistakes to Avoid
Several common mistakes can hinder the performance of Intermatic timers:
- Overloading the Timer: Exceeding the timer’s rated voltage or amperage can damage the device and create a safety hazard.
- Incorrect Wiring: Wiring the timer incorrectly can lead to malfunctions, short circuits, or even electrical shock.
- Ignoring Compatibility: Ensure the timer is compatible with the type of electrical load being controlled (e.g., incandescent, LED, motor).
- Neglecting Maintenance: Periodic cleaning and inspection can help prevent issues and prolong the lifespan of the timer.
- Forgetting Battery Replacement (Digital Timers): Failing to replace the battery backup in digital timers can result in lost settings and inaccurate timekeeping.
Intermatic Timer Troubleshooting Tips
Here’s a quick troubleshooting guide for common Intermatic timer problems:
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer not turning on/off | Power outage, incorrect settings, faulty switch | Check power supply, verify settings, replace the timer |
| Timer running slow/fast | Motor malfunction (mechanical), clock error (digital) | Replace motor (mechanical), reset/replace timer (digital) |
| Lights flickering | Loose wiring, faulty switch | Check and tighten connections, replace the timer |
| Programmed settings lost | Battery failure (digital) | Replace battery |
Installation Guide (General Steps)
Although installation varies by model, here’s a general overview:
- Safety First: Disconnect power to the circuit at the breaker box.
- Identify Wires: Determine the line (power source) and load (device being controlled) wires.
- Connect Wires: Connect the wires to the corresponding terminals on the timer, following the wiring diagram provided with the timer.
- Mount the Timer: Securely mount the timer in its designated location.
- Restore Power: Turn the breaker back on and test the timer’s operation.

Frequently Asked Questions (FAQs)
Can I use an Intermatic timer to control a pool pump?
Yes, Intermatic offers specific timers designed for pool pumps. These timers are rated for the higher voltage and amperage requirements of pool pump motors and often include features like freeze protection.
What is the difference between a mechanical and a digital Intermatic timer?
Mechanical timers utilize gears and a synchronous motor to track time, while digital timers use a microprocessor and electronic components. Digital timers offer greater precision, flexibility, and programmability.
How do I program an Intermatic digital timer?
Programming varies depending on the model, but generally involves using the buttons on the timer to set the current time and create on/off schedules. Consult the user manual for specific instructions.
What is an astronomic timer and how does it work?
An astronomic timer automatically adjusts on/off times based on sunrise and sunset times. It uses a built-in calendar and location data to calculate these times, eliminating the need for manual adjustments.
How do I replace the battery in my Intermatic digital timer?
The battery location and type vary by model. Typically, you’ll need to remove the timer from its enclosure and locate the battery compartment. Replace the battery with the correct type and voltage, following the manufacturer’s instructions.
