Ventilation Hood Heat Sentry Feature
Topics:
- Why did the hood turn on and off on its own?
- Why did the blower speed increase then decrease on its own?
- PW, PWC, PL, PI, IH, CTWH, and CTEWH heat sentry.
- At what temperature does the ventilation hood heat sentry turn on or turn off?
- What temperature activates or deactiviates the heat sentry feature?
- Why is the blower speed LED flashing?
Answer:
CT Wall, CT Island, CTE Low Profile, and all Pro Series Ventilation Hoods are equipped with a heat sentry feature, which automatically turns the ventilation hood on, or adjusts the blower speed to the next highest setting when excessive heat is sensed.
- The heat sentry feature activates when the exhaust temperature reaches 200°F (93°C) and deactivates when the exhaust temperature decreases to 185°F (85°C).
- If the ventilation hood is turned off and the heat sentry senses 200°F exhaust, the blower automatically turns on.
- Once the exhaust temperature decreases to 185°F, the blower turns off.
- If the ventilation hood is turned on to low speed and the heat sentry senses 200°F exhaust, the blower increases to high speed.
- Once the exhaust temperature decreases to 185°F, the blower decreases back to low speed.
For CT Wall, CT Island, and CTE Low Profile Hoods:
- The corresponding blower speed LED on the control will blink to indicate the heat sentry feature is activated.
- Once heat sentry feature is activated, the ventilation hood will continue to monitor exhaust temperatures every 3 minutes.
- When the blower speed returns to the original setting prior to heat sentry feature activation, the corresponding LED will stop blinking and remain constant.
- When the heat sentry feature is active, the customer will not have any control of the blower speed until the exhaust temperature decrease to 185°F.
