Text Messaging Commands
Command
DATE
Text Messaging Display - Date
26
Description
ViewStat has a counter and can maintain a clock, once set, with reason-
able accuracy over a 24-hour period. Therefore it is necessary to send
ViewStat the current Date and Time from the automation system at least
once per day. Each variable, Date and Time, has its own command.
Date is sent in 6-digit form and will be displayed on the text messaging dis-
play as the same six digits, with each set of two separated by a "-". Date
values with less than 6 digits, or with any of the three numbers higher than
the allowable limit, will be seen as an error and the command will not be
carried out. For example the command SN1 DATE = 122304 will result in
the display reading "12-23-04". The thermostat does recognize that there
are not more than 31 days in a month, and that there are no more than 12
months, but does not recognize months with less than 31 days.
It is important to update the date value at least once per day as date
values do not automatically increment.
Should the Date value not be updated, the thermostat could read "02-31-
02".
If a Date value has been sent to the thermostat, it will be displayed in addi-
tion to the four Rotating Message Display messages (see PMES1-PMES4)
as a fifth message. It will be shown as the top line of the two line text mes-
saging display. Should there not be a Date value, only the four Rotating
Message Display messages will be displayed.

SN[address] DATE=MMDDYY
