iGrow1800 - Programming Deadbands

With the iGrow1800 controller, you can set up deadbands. Here is a video to give you a more deeper understanding.


Temperature Deadband - For cooling, it is the number of degrees the temperature needs to drop from the lower boundary of its current stage before it switches to the lower stage. Without Deadbands, equipment tends to cycle frequently & constantly change stages when the temperature approaches the set points. When a large value is used, setpoints may not be maintained. Typical values might be 1 to 2 degrees F. For heating it is the number of degrees the temperature needs to rise above the temperature boundary before it switches to a lower heating stage.

RelHum Deadband

This is the RH% the humidity must drop below the dehumidification threshold before exiting the dehumidification state.  It also is the RH% the humidity must rise above the humidification threshold before exiting the humidification threshold.

 Bheat Deadband

This is the number of degrees that the bottom heat temperature must rise above the bottom heat temperature setpoint or threshold before the heat valve switches off.  Typical values might be 1 degree F or less.

Temperature Deadband is in Degrees

Relative Humidity Deadband is in Percentages

Bottom Heat (Mix valves/Micro zones) is in Degrees

C02 Deadband is in PPMs

Note: Make sure your Deadband values do not exceed Stage width or the distance between a lower and higher set point

For example, don’t make your deadband for relative Humidity 10% if Humidify is 40% and Dehum is 47%.

Now to get to the deadband programming screen from home screen hit Enter/Menus -> then go into System Setup -> and then Setup Deadbands.
