Frequently Asked Questions

What temperature is the temperature controller set to from the factory?

95º Fahrenheit.

Will the temperature interlock automatically start/ stop the fans?

When connected properly to fan starters the temperature interlock will automatically control the fans without input from the user. However, the intended use of the temperature interlock is as back- up to manual control.

May I connect the power going to my fan directly through the control box?

No, the control box should only use control voltage only (24-120V), and a separate 120V power source is required to run the temperature interlock controls. Greenheck recommends the use of starters sized for each fan.

Can I use one control box for multiple hood systems?

This can be done, however, it is not recommended. Any one of the temperature controllers would turn on all hoods running on that control box. It is better to have one hood/fan per control box, plus a significant energy savings can be obtained if one or more of the hoods is not in operation.

Can I still turn my fan on and off?

Yes, the temperature interlock is designed to be operated with a typical on/off switch. The fan may not turn off directly after turning the fan switch off, it will sense when the cooking operations have cooled and then turn off.
