This thermostat can operate on a programmable schedule in order to automatically
lower the room temperature setting. Options include:
• Turning off the schedule (OFF)
• Operate a schedule that applies only to this thermostat zone (ZONE)
• The ability to operate one of the four system-wide schedules as a master (Schedule
Master 1 through 4*)
• Join one of the four system-wide schedules as a member (Schedule Member
1 though 4*)
*Requires the thermostat to be connected to a tekmarNet
Once the type of schedule has been selected, the thermostat can support schedules
that have either:
• 2 events per day
• 4 events per day
Schedules with four events per day are common for residential use while two events
per day are common for commercial installations.
The schedules can be repeated every:
• 24 hours
• 7 days (week)
A 7 day schedule allows a unique time to be set to change the temperature for
each day of the week.
The schedule also includes a "SKIP" option that allows the programmable schedule
to skip a temperature change and remain at the previous temperature setting. The
"SKIP" setting can be found between 11:50 PM (23:50 hours) and 12:00 AM (0:00
hours).
When a programmable schedule is selected, there is a time delay for the room to
warm up from the
option to use Optimum Start to predict the heat up rate of the room. When Optimum
Start is set to On, the heating is started in advance to allow the room to reach the
Set Room temperature at the time set in the programmable schedule.
