Model 3940 Series 4-3 Thermo Electron Corporation
Section 4
Service
The Watlow temperature and humidity controllers have been set at the
factory to operate the incubator within the specifications listed in the
Specifications section of this manual. Reference copies of the Watlow
configuration records are included at the end of this section.
To prevent tampering, mechanical and software lockouts are employed in
the system. These lockouts must only be removed by persons skilled in
configuring controller software.
Caution
Re-programming either the temperature or humidity controllers
alters the factory defaults and will seriously alter the performance of the
incubator. This may also void the warranty. Do not re-configure the
controllers without first consulting the Technical Services Department,
(888) 213-1790.

pull the controller module out of its frame.
