Two Timers, Two Very Different Jobs
If you are shopping for a kennel ventilation timer, the 12-V DC Timer Switch and the TORK Percentage Timer can look like alternatives. They are not interchangeable. The 12-V DC Timer Switch controls low-voltage equipment such as a compatible DC exhaust fan or a 12 V lighting system. The TORK Percentage Timer is a percentage-based controller for a compatible electric exhaust fan, letting you set how long the fan runs within a cycle.
The right pick depends on what you are trying to automate: simple on/off scheduling for lights or a DC fan, or duty-cycle control for a larger ventilation fan. Below, we break down the evidence for each so you can match the timer to your kennel's airflow and humidity control needs.
What the 12-V DC Timer Switch Controls
- 12-V DC Timer Switch: Compatible with a DC Exhaust Fan or a 12 V lighting system. This timer is built for low-voltage kennel equipment, so it suits lighting schedules and small DC fan control rather than high-voltage ventilation.
12-V DC Timer Switch - 12-V DC Timer Switch: Can turn lights on in the morning and off at night. A simple daily light schedule saves time and supports a consistent routine in a boarding or breeding kennel.
- 12-V DC Timer Switch: Can activate kennel fans to help maintain a regulated temperature. If your airflow plan relies on a compatible DC exhaust fan, this timer can automate when that fan runs.
What the TORK Percentage Timer Adds
- TORK Percentage Timer: Two dials adjust cycle time from 15 seconds to 24 hours and on-time percentage, with 32 settings from 0% to 100%. This gives you fine control over how long a fan runs within each cycle, which is useful for matching airflow to changing humidity or temperature.
TORK Percentage Timer - TORK Percentage Timer: Compatible with the Electric Exhaust Fan With Shutters. The percentage timer is designed to work with a specific high-volume fan, so it fits a more automated ventilation system.
- TORK Percentage Timer: Example: set kennels to run only 70% of the time each hour, and the timer handles the rest. Percentage-based scheduling prevents a fan from running longer than needed, which can save energy and reduce electricity costs.
Percentage Timer vs DC Timer: Which Fits Your Airflow Plan?
- Control style: The 12-V DC Timer Switch provides simple on/off scheduling for lights or a DC fan. The TORK Percentage Timer controls what percentage of a cycle a fan runs, with adjustable cycle times.
- Equipment compatibility: The DC timer works with a compatible DC exhaust fan or 12 V lighting system. The TORK timer is compatible with the Electric Exhaust Fan With Shutters.
- Best for: Choose the DC timer for basic daily light schedules or low-voltage fan control. Choose the TORK timer for automated duty-cycle ventilation in boarding or commercial kennels where airflow needs vary.
- Humidity control: Neither timer senses humidity directly. The TORK timer's percentage settings let you adjust run time as conditions change, but you still need to monitor humidity separately.
What the Catalog Does Not Specify
The supplied records do not list enclosure ratings, mounting details, or wiring instructions for either timer. The 12-V DC Timer Switch record advises protecting the timer from rain and dirt, but does not state an IP rating. The TORK Percentage Timer record does not include environmental protection details. Before installing either timer, check the full product documentation for your kennel's electrical setup.
Neither record provides humidity sensing or automatic adjustment based on humidity levels. If humidity control is your primary goal, a timer can schedule airflow, but you will need a separate humidity monitor and manual adjustments.
