3. Product Overview
Familiarize yourself with the components of your Westek TM1609DHB timer.

Components:
- Programming Dial: A rotating dial marked with 24 hours (AM/PM) for setting the current time and programming on/off cycles.
- Programmable Pins: Non-removable segments around the dial. Each segment represents 30 minutes. Pushing a pin DOWN activates the connected device during that time; leaving it UP deactivates it.
- Manual Override Switch: Located at the top, this slider switch allows you to bypass the timer settings and manually turn the connected devices ON or OFF.
- Grounded Outlets: Two three-prong outlets, one on each side of the timer, for connecting your devices.
- Power Plug: A three-prong grounded plug on the back of the unit for connecting the timer to a wall outlet.
4. Setup and Installation
4.1 Setting the Current Time
- Locate the arrow on the inner white dial, labeled "TIME". This arrow indicates the current time.
- Rotate the entire outer dial clockwise until the current time aligns with the "TIME" arrow. Ensure you correctly distinguish between AM and PM hours. For example, if it's 3 PM, align '3 PM' on the dial with the arrow.
4.2 Programming On/Off Times
The outer ring of the dial consists of multiple pins, each representing a 30-minute interval. These pins are non-removable.
- To set a device to turn ON, push the corresponding pins DOWN for the desired time duration.
- To set a device to turn OFF, leave the corresponding pins UP for the desired time duration.
- You can program up to 24 ON/OFF settings per day.
Example: If you want a light to turn on from 6 PM to 10 PM, push down all the pins between the '6 PM' and '10 PM' markings on the dial.
4.3 Connecting Devices
- Ensure the timer is unplugged from the wall outlet before connecting any devices.
- Plug the device(s) you wish to control into the grounded outlets on the sides of the timer.
- Plug the Westek TM1609DHB timer into a standard 125VAC, 60Hz grounded wall outlet.
5. Operation
Manual Override Switch
The slider switch at the top of the timer allows you to manually control the power to the connected devices, overriding the programmed settings.
- Slide the switch to "OUTLET ON" to keep the connected devices continuously ON, regardless of the timer settings.
- Slide the switch to "TIMER ON" to enable the programmed ON/OFF cycles. The devices will operate according to your pin settings.
