Installation Instructions
WARNING: Ensure power is disconnected at the main circuit breaker before proceeding with installation.
- Mounting the Enclosure: Select a suitable location for mounting the timer. The steel enclosure is rated for indoor and outdoor use. Securely mount the enclosure to a flat, stable surface using appropriate hardware through the mounting holes provided.
- Wiring Connections:
- Open the enclosure door.
- Identify the input power terminals (LINE) and output load terminals (LOAD).
- Connect the incoming power supply wires to the LINE terminals.
- Connect the wires leading to the electrical load (e.g., pump, lighting) to the LOAD terminals.
- Ensure all connections are tight and follow the wiring diagram located inside the enclosure or in the separate instruction guide.
- The T106R is designed for 208-277 Volt applications. Verify your supply voltage matches the timer's rating.

Operating the Time Switch
Setting the Current Time
- Rotate the large yellow dial clockwise until the current time aligns with the small arrow or indicator mark on the timer mechanism.
- Ensure AM/PM is correctly set if applicable (this model operates on a 24-hour cycle).
Programming ON/OFF Cycles
The timer uses trippers (pins) on the dial to activate ON and OFF cycles.
- Locate the ON (green) and OFF (red) trippers. These are typically small pins that can be pushed in or out, or attached to the dial.
- Attach or position the ON tripper at the desired time for the load to turn on.
- Attach or position the OFF tripper at the desired time for the load to turn off.
- Multiple ON/OFF cycles can be set, up to 12 pairs per 24-hour period. Ensure a minimum of 1 hour between ON and OFF settings.
Manual Override
The T106R includes a manual override switch, typically a lever or button, that allows you to temporarily turn the load ON or OFF without affecting the programmed schedule.
To use: Move the manual override lever to the desired position (ON or OFF). The timer will resume its programmed schedule at the next scheduled ON or OFF event.
Maintenance Guidelines
- Cleaning: Periodically clean the exterior of the enclosure with a damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Annually inspect the wiring connections for tightness and signs of wear or corrosion. Ensure the enclosure door seal is intact.
- No User Serviceable Parts: The internal mechanical components are not user-serviceable. If the timer malfunctions, contact a qualified electrician or Intermatic support.
