This thermostat can operate on a
programmable schedule in order
to automatically lower the room
temperature setting. The schedule
can be off or on.
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 p.m. (23:50 hours) and
12:00 a.m. (0:00 hours).
Optimum Start
When a programmable schedule is
selected, there is a time delay for
the room to warm up from the
temperature to the temperature.
The thermostat has 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. The
optimum start only applies to radiant
floor heating, baseboard or radiator
heating and does not apply when
a forced air fan is used with the
heating system.
