Changing the CO
2
Set-point (CO2C301)
If an alternative CO
2
set-point is required, the following steps can be taken:
Press the up arrow to increase the CO
2
set-point by 0.1% CO
2
. Press the down arrow
to decrease the CO
2
set-point by 0.1% CO
2
. Pressing and holding either button will
cause the set-point to scroll rapidly in either direction.
If CO
2
is not required in the chamber, the CO
2
system can be disabled by turning off
the Enable CO
2
switch. This will disable the entire CO
2
system including the controller.
The system can be turned back on at anytime.
Operation of the Delux Controller System (DLUX301 & DLUX302)
The chambers can be purchased with upgraded controllers. The controllers have
additional features of RS485 communications, analog outputs, and ramp & soak.
RS485 Communications:
Each controller on the network (connected to the same PC or master device) must be
programmed with a unique address. If multiple chambers are being connected, each
controller will have to be assigned a unique address. Factory defaults for the
controllers are addresses 1 for temperature and 2 for humidity. As an example, a
second chamber would need to be assigned address 3 for temperature and 4 for
humidity. To assign new addresses to controllers, the controllers must be unlocked.
Refer to Section 13, Unlocking the Controllers.
