Cycle on time Allows you to enter the number of minutes for the cooling system to
be on while the 509ITM is learning the system parameters.
Cycle off time Allows you to enter the number of minutes for the cooling system to
be off while the 509ITM is learning the system parameters.

6. Click [Initialize].
The cooling system begins to cycle. The relay controlling the fan/pump motor de-
energizes for the time entered in the
Cycle off time field. When the time expires, the
relay/cooling system toggles on and off until it reaches the number in the Test Cycles
field. The approximate time to run the initialization cycle can be calculated by:
(((Cycle Time On + Cycle Time Off) * Test Cycles) + Cycle Time Off)
