Setup and Installation
Note: Installation must be performed by a qualified electrician and comply with all local and national wiring regulations.
- Preparation: Before beginning, ensure the mains power supply to the immersion heater circuit is completely switched off at the consumer unit (fuse box).
- Mounting: Select a suitable, dry indoor location for the timeswitch, typically near the immersion heater or consumer unit. Secure the timeswitch to the wall using appropriate screws and wall plugs.
- Wiring:
- Connect the incoming Live (L) wire from the mains supply to the terminal marked 'L IN'.
- Connect the incoming Neutral (N) wire from the mains supply to the terminal marked 'N IN'.
- Connect the Earth (E) wire to the Earth terminal.
- Connect the Live (L) wire going to the immersion heater to the terminal marked 'L OUT'.
- Connect the Neutral (N) wire going to the immersion heater to the terminal marked 'N OUT'.
- Secure Connections: Ensure all terminal screws are tightened securely to prevent loose connections and overheating.
- Close Casing: Carefully replace the front cover of the timeswitch, ensuring it is properly seated and secured.
- Power On: Restore mains power supply to the circuit at the consumer unit.

Operating Instructions
- Setting the Current Time: Rotate the outer dial clockwise until the current time aligns with the 'TIME' arrow indicator. The dial is marked in 24-hour format (e.g., 13 for 1 PM, 18 for 6 PM).
- Programming ON/OFF Periods:
- The dial's circumference is divided into segments, with each segment representing 15 minutes.
- To set an 'ON' period, push the corresponding segment pins outwards.
- To set an 'OFF' period, ensure the corresponding segment pins are pushed inwards.
- For example, to have the immersion heater ON from 07:00 AM to 08:30 AM, push out all pins between the 07:00 and 08:30 markings on the dial.
- Manual Override: The timeswitch includes a manual override switch, typically a slider or button, with positions such as 'ON', 'AUTO/TIMER', and 'OFF'.
- ON: Keeps the immersion heater continuously ON, overriding any programmed settings.
- AUTO/TIMER: Allows the timeswitch to operate according to the programmed ON/OFF settings. This is the standard operating mode.
- OFF: Keeps the immersion heater continuously OFF, overriding any programmed settings.
Maintenance
- Cleaning: Wipe the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the unit or cause electrical hazards.
- Inspection: Periodically inspect the timeswitch for any signs of physical damage, loose wiring, or discoloration. If any issues are observed, immediately disconnect power and consult a qualified electrician.
- No User-Serviceable Parts: The internal components of the TS900N are not user-serviceable. Do not attempt to open the unit beyond accessing the wiring terminals during installation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Immersion heater not turning ON/OFF as programmed. | Incorrect current time setting; Pins not pushed out/in correctly; Manual override engaged. | Check and adjust the current time setting; Ensure pins are correctly set for desired ON/OFF periods; Set the manual override switch to 'AUTO' or 'TIMER'. |
| No power to the timeswitch. | Mains power supply is off; Loose wiring connection; Blown fuse or tripped circuit breaker. | Check the mains power supply to the circuit; Verify all wiring connections (consult a qualified electrician if unsure); Check the fuse or circuit breaker at the consumer unit. |
| Timeswitch making unusual noises (e.g., grinding, buzzing). | Internal mechanical fault. | Immediately disconnect power to the unit. Do not attempt to repair. Contact a qualified electrician or Timeguard customer support. |
