Setting temperatures
Press the Up or Down adjust button . The setting to be changed will begin to flash. Press and hold
the button to change the setting.
If operating in the
HEAT
mode, the only temperature set point available to change is the
Heat setting. When the room temperature drops below this setting the heat will come on
(call for heating) to raise the temperature.
EM. HEAT
mode uses the
HEAT
setting.
If operating in the
COOL
mode, the only temperature set point available to change is the
COOL
setting. When the room temperature rises above this setting the Cooling will come
on (call for cooling) to lower the temperature.
If operating in
AUTO
(
HEAT
or
COOL)
mode, the first press of the Up or Down adjust
button will indicate which of the two temperature settings will be adjusted – it will be the
one flashing.
If this is not the desired temperature to adjust, press the Mode button to access the other
temperature setting.
Fan operation
The thermostat can operate the fan either continually (
FAN ON
), or only during Heating and
Cooling calls. Press the Fan button to toggle between these two options.
FAN ON
is recommended
for media/electronic air cleaners, ventilating equipment, and to allow for humidification in mild
climates.
Backlight operation
Operation of the backlight is configured in the Thermostat Set-Up. Depending on the set-up, the
backlight will light at the press of any button, or it can be disabled (see the Backlighting Set-
Up section on page 48). The backlight will stay on for 10 seconds after the last press of a button.
Network override
If the Network Override has not been disabled in the Thermostat Set-Up, the Network Override can
be initiated by pressing the Enter button. When initiated, the thermostat is taken offline from the
automation system. The thermostat can then only be operated at the thermostat. Pressing the Enter
button again will restore network communication.
Clearing a temporary flashing message
Custom Home Automation systems have the ability to send a temporary message to the message
display. This message will flash until the user acknowledges the message. To acknowledge message
press the Enter button.
Do not set to OFF mode during periods when freezing temperatures could occur.
