mode the stage operates as.

a stage on the system timer (5 or 10 minutes).

9.2 Setting Up Tunnel Control
Note: If you do not want the controller to ever enter tunnel mode just make sure that the
Tunnel On/Off switch is in the off position and you can ignore this section.
The 4 Stage Controller is a very versatile tunnel controller. It provides the grower with
many different ways to tunnel based on the layout of the house. It also provides two
different ways of initiating tunnel mode. The following are some tips and examples of
setting up this controller to tunnel your house appropriately.
1. The first step in setting up your tunnel house is to configure the stages that you want as
your cool tunnel stages. If some stages need to operate in tunnel mode and in normal
mode, then program these stages to be cool negative tunnel stages. See the Program
Reference section in the back of this manual for more information on the operation of
various stage modes.
