Menu Setpoints
Full Setpoint Access
Set Time & Date
The System Manager has its own built in Real Time Clock. It broadcasts this time once a
day, at midnight, to synchronize all of the WHPs on your system. Although the times are
displayed on the Main Screen in a standard 12-hour format, they are programmed using
the 24-hour Military format. Once the time has been entered, it is also broadcast
immediately to all other units on the system. That means that you only need to program
the System Manager time to set the Real Time Clocks for all units on your system. In
order for the System Manager to broadcast the time and date to all controllers, they must
be powered up and communicating.
Programming Time
If you selected the Menu key from the first menu screen you
can access all setpoints available from any unit on your system.
You must be a Level 2 user to access these setpoints. If you
haven’t already been asked to enter the passcode, you will be
asked before the Full Setpoint Access menu is displayed. This
prevents the casual user from being able to affect the operation
of your heat pump system.
