Thermostat Operation
Setting Time and Day
Normally, time is automatically set by the MyE website. In case the user opts out of web control,
setting time is accomplished by the steps below:
•
Press
Set Time
button and the hours starts flashing as one unit (both digits together). The
hour will be set from 1-12 using the
Up
and
Down
buttons.
•
Press
Set Time
button again and the tens digit of the minutes begins flashing. Set the tens
minute digit by using the
Up
/
Down
buttons.
•
Press
Set Time
button again and the ones minutes digits should begin flashing. Set the
ones minute digit by using the
Up
/
Down
buttons.
•
Press
Set Time
button again and the AM/PM units should begin flashing. Set the AM/PM by
using the
Up
and
Down
buttons.
•
Press
Set Time
button again and the current active day will begin flashing. Pressing the
Up
/
Down
buttons will flash the next day/previous day, respectively.
•
At this point, pressing the
Set Time
button again will start the cycle again by flashing the
Hour units and so on. Only when “
Hold/Run
” is pressed is the change accepted and the
set time mode exited.
•
If ANY other button is pressed (other than Set Time, Up, Down), then the set time mode
should be canceled and the time/day reverted to the time before
Set Time
was pressed.
Hold Temperature
There are multiple hold situations. There is a Temporary Hold, a Smart Hold and a Smart Grid Hold.
The Temporary Hold is the traditional hold that will switch back to the programmed set point at the
next mode change. The Smart Hold uses some intelligence to determine how long to keep the Hold
active. The Smart Grid Hold is a hold initiated and ended by a Utility through a Smart Meter.
Temporary Hold
•
While in normal operation, after pressing the
Up
/
Down
button, the set point will start to
flash for 5 seconds. If
Hold/Run
is not pressed within this period, a temporary hold will be
set. This will cause the “Temp Hold” element on the thermostat screen to flash to indicate
that the thermostat is in Temporary Hold. “Temp Hold” will continue flashing until the
Temporary Hold is canceled or the next program mode takes effect.
