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.

•While a Temporary Hold is in effect, pressing the Up/Down buttons will change the hold
temperature but keep the hold in Temporary mode.
•Once in the Temporary Hold, press the Hold/Run will cancel it and resume the current
program.
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 pressed within this period, a normal hold will be set,
and “Hold” alone will be lit.
•Once in Hold mode, pressing Hold/Run button again will release it manually..
Smart Grid Hold
•The Smart Grid Hold is activated and ended by the Utility through a Smart Meter. When
active, “Smart Grid” and “Hold” flash together. When the DR event is canceled by the Utility,
the “Smart Grid” and “Hold” elements will be turned off.
•The user cannot initiate the Smart Grid Hold, but the user can cancel it by pressing the
Hold/Run button once, which will turn off the “Smart Grid” and “Hold” elements and revert
the thermostat to its previous state. That previous state could be a temporary hold, a smart
hold, or running the current program.
•While a Smart Grid Hold is active, the user cannot change the temperature UNLESS they
cancel the Smart Grid Hold first.
Conne tions – WWW (Internet) and Smart Grid
The MyE Thermostat has multiple wireless connection possibilities. It can connect to the Internet
via the Mediator and it can also connect to the Utility Smart Grid.
Mediator
Without a connection to the Mediator, the thermostat will not be able to have internet connection.
If the connection between the Mediator and Thermostat cannot be established, then the “signal
strength” icon will show 3 empty bars and the antenna will flash.
Smart Grid
The Smart Grid connection is used by the Utility to send pricing messages and Demand Response
events to the thermostat. This Smart Grid connection is not universally available.
•If your Utility does has a Smart Grid and your home is equipped with a Smart Meter, and
the thermostat is able to communicate with the Grid, “Smart Grid” should be lit on the
Thermostat screen.
•If a Smart Grid exists but the signal is lost, then “No Smart Grid” will flash.
•If a Smart Grid exists but the Smart Grid control has been user disabled (See Conne tion
button), then “No Smart Grid” should be lit.
If the thermostat is connected to a Smart Grid, the following becomes available:
-Cost: current electricity prices.
-Power: instant home electrical power usage in Kw.
-“High Cost” indicator: indicate that a high electricity cost event is in effect.
See “Menu button” for further information
-Demand Response capabilities that allow the Utility to set a specific temperature for your
thermostat until the DR event is over. This can be overridden. See the “Hold Temperature”
section for more information and how to override the Smart Grid Hold.
WWW Control
When the thermostat has the connection to the internet via the mediator, it can be controlled and
monitored via you myenergydomain.com account. All controls provided on the thermostat panel

can also be initiated from the web dashboard, plus that the Daily and Weekly programs, vacations/
staycations are set via a user friendly interface on the website. If you disable WWW Control use
Conne tions button, then the thermostat will be controlled locally only, but you can still monitor
its status via the web.
Lo king the thermostat
The thermostat has the ability to be locked, meaning that most keys will not function. The purpose
of the lock is to keep inadvertent or unwanted changes from being performed. The lock can be
activated and deactivated from both the website and on the thermostat itself.
•To lock or unlock the thermostat using the buttons on the thermostat, simultaneously press
Conne tions + Up + Down buttons.
•When locked, the only button that will function is the Menu button to allow changing the
information displayed on the screen.
•When locked, the LOCK icon will be visible.
