PROGRAMMED OPERATION
Introduction
The Universal Application Programmable Thermostat provides
four periods per day (MORN, DAY, EVE, NIGHT) and two
schedules per week (MoTuWeThFr and SaSu). A separate time,
heat setpoint, and cool setpoint can be set for each period and
schedule. Before starting to actually program the thermostat, fill
out Table 1 with the values you wish to program. (The factory
default time and temperature values are already programmed for
you as a starting point and are shown in Table 1.)
The first press of the SET button brings up the programming mode
and places you at morning (MORN) of the MoTuWeThFr
schedule. Successive presses move you between the four daily
periods.
While Programming:
The TEMP/TIME button moves between three selections of SET
TIME, SET TEMP & HEAT, and SET TEMP & COOL. These
three numbers are to be programmed for each of the periods
MORN, DAY, EVE, and NIGHT. The DAY button moves between
the weekdays, (MoTuWeThFr) and the weekend (SaSu) selections.
A different schedule may be set for the weekdays and the weekend.
You may exit programming at any time by pressing the
HOLD/END button.
