HVAC Products Timer Function 19.01.2004
7 Timer Function
Notes:
• Before using the timer function as a control method, set the AOP real time clock as described
in the Set Time/Date section.
• Setting a timing event for ‘every day’, configures the same event for each day of the week
separately. To clear an ‘every day’ event, you must clear the event individually from each day.
• When multiple events must be cleared from the Timer function, it may be easier to reset the
AOP as described in the AOP Reset section.
• When in MASTER mode of operation and viewing the connected SED2 drives, a ‘T’ displays in
the top left corner to indicate that the connected SED2 drives are under timed remote control
and may start or stop unexpectedly.
• To start or stop an attached SED2 VSD with the AOP timer function you must set the com-
mand source parameters P0700[0]=4 and P0700[1]=4 (USS on BOP link or AOP).
7.1 Setting the AOP Timer
When in LOCAL or MASTER mode, you can access the timer feature from the main menu. The timer operates
as a 7-day, time-of-day, on/off controller (much like a central heating controller but with the addition of a possi-
ble multi-VSD selection).
