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.
