16A Love Controller – Guide
1. There are three menu's in the 16A21XX(-XXX) Love Control
a. Primary Menu.
i. Used for setting temperature.
ii. To access the Primary Menu, press the scroll button once to access SP1,
twice to access SP2.
iii. Use the arrow keys to make any changes and press Enter to save them.
b. Secondary Menu.
i. Sets PID parameters as well as other items associated with the control of
the chiller.
ii. To access the Secondary menu, press the up arrow and the enter key
simultaneously and release.
iii. Press the scroll button to scroll to each item in the menu. Use the arrow keys
to make any changes and press Enter to save them.
c. Secure Menu
i. Used to set basic items such as the input device, the displayed units as well
as setting up how the contacts will operate.
ii. To access the Secure menu, press the up arrow and the enter key
simultaneously and hold for five seconds. Press the scroll button to scroll to
each item in the menu. Use the arrow keys to make any changes and press
Enter to save them.
2. Please note that when programming a control from its default program you must go through
the menu's in this order: Secure, Secondary, Primary. The reason for this is that items set in
the Secure menu determines which items are displayed in the Secondary menu and how the
Primary menu is displayed.
3. Typically the controls are shipped from Opti Temp in a locked state. They can be unlocked by
entering a code found in the controller user manual.
4. We ship the controllers with a generic program that provides good control in most cases. If
the control is not as precise as required the controller has a self tune mode. See the
controller user manual for more information.
5. Unless otherwise noted DO NOT set SP2 to anything other than its factory setting,
typically zero. You may experience a loss in overall capacity if changed from its
factory setting.
