Schedules
Section D
Lowering the room temperature setting reduces the amount of fuel required to heat
the building resulting in energy savings.
This thermostat can follow a programmable schedule in order to automatically
lower the room temperature setting. A schedule master such as a Timer 033e is
required in order to gain programmable schedule functionality.
When operating on a programmable schedule, a symbol is shown, as well as a

Section E
When a programmable schedule is selected, there is a time delay for the temperature
to change from the temperature to the temperature.
The thermostat uses Optimum Start to predict the heat up and cool off rate of
the room. The optimum start feature allows the room to reach the set room
temperature by the time set in the programmable schedule. This applies for both
heating and cooling.
Scenes provide an easy way to save energy while away on vacation, or override a
pre-set schedule when plans change. tekmarNet
