rogramming Overview
Thermostat programming is a 3-part process: setting
current time, choosing event setpoints, and setting
event times. Throughout the programming procedure,
the following terms will be used:
Event
= morning, day, evening, night
Event time
= the time the event starts
Event setpoint
= the temperature setpoint of the
event; each event can have only one setpoint for
heating or cooling.
Program flexibility is achieved by varying the program
start times. When consecutive events are programmed
with the same event time, the thermostat will control
the temperature according to the setpoint of the latest
event.
Table 7 is an example of event times and setpoints for
a given week using a 4-event program. See the
owner’s manual for a blank table.
Note:
A 2-event program will only include day
and night events.
