The defrost lockout parameters allow the customer to prevent the unit from going into a defrost cycle for two hours during
a set time frame. Customers can set up to four defrost lockout parameters. They are all programmed the same way. The
parameters will be set for the time the lockout is to start. The controller automatically calculates 2 hours from that setting.
The options are similar to the 24-hour clock settings and are in 30-minute increments. Each of the lockout parameters
covers 6 hours of the 24-hour clock. Note: The 24-hour clock must be set for this feature to operate at the correct time of
day. See “Setting the 24-Hour Clock” on page 11.

A lockout can not be programmed to start at 12:00 am or 12:30 am due to conflicts with other internal programs. The
defrost lockouts can not be programmed to run back-to-back. For example, if dL1 is set to 080, then a defrost cycle
would be locked out from 8:00 am to 10:00 am. Because of the dL1 setting the dL2 parameter would not let the user
choose a lockout start time before 10:30 am. All lockouts are preset at the factory to OFF.
Follow the instructions to enter the customer access code on page 8. When the control
displays Thermostat Set High, press the down arrow key until the control the
