Cooling Cycle 5.0 sec 0.5 to 60.0
Time base for solenoid cooling valve. If Cooling Cycle is set to 5.0s, and
the unit is cooling at 50% capacity, the solenoid cooling valve will
alternate between 2.5s on and 2.5s off.
Heating Cycle 10.0 sec 0.5 to 60.0
Time base for heater contactor. If Heating Cycle is set to 10.0s, and the

Track Health Yes
No
Yes
Provides machine run statistics and alarm counting for the diagnostics
menu. This can be disabled to decrease processor load or not track these
items.
Diagnostics No
No
Yes
Select “Yes” to enter the Diagnostics menu. Note: Since you have already
authenticated as a factory user, you will have WRITE access to directly
control outputs for troubleshooting (except for heater output).
Load Defaults No
No
Yes
Select “Yes” if you would like to load defaults for all user AND factory
parameters. If you select “Yes” all your customized settings will be
permanently lost and default user and factory parameters will be used
instead. The controller will reboot after implementing default settings. As a
factory user, you will need to then go back and properly configure the
factory menu according to the installed TCU options.
Note: The unit will not operate properly if the Factory Parameters are incorrectly changed or modified. For that reason these parameters can only
be changed once the Factory Menu is activated in the User Parameter menu (see screen 6/6 under User Parameters). Only qualified technical
personnel familiar with the operation of the unit should change these parameters and then only at the direction of someone from the factory
Customer Service Department.
