Battery Replacement - Honeywell Home T10 Product Data

Custom Alerts 1 through 4
Allows the dealer to enter a custom alert to be displayed when
a dry contact device is activated. For example, a float switch
can detect when your sump pump is not working.
When Custom Alert 1 through Custom Alert 4 is selected in
ISU 6005, the T10+ asks you to name the alert and then gives
options for additional settings related to the alert. These
settings are:
• Which set of S terminals on the EIM the Dry
Contact Alert is wired to (ISU 6190).
There are four (4) sets of configurable S terminals on the
EIM. If a set of S terminals is already configured for use by
a different Dry Contact Alert (or sensor), it will not be
configurable.
• Whether the switch wired to these terminals is
normally open or closed (ISU 6200).
The switch wired to the S terminals could either be open in
normal (not alert) conditions or closed.
• Enter the Dry Contact Alert name (ISU 6210).
• Whether there is an alert message displayed
when the alert is active (ISU 6215).
In most cases, the installer would want an alert message to
appear on the T10+ if there was a Dry Contact Alert active.
However, the installer may be using the "alert" to do some
other action (like running a ventilator when a sensor is
reading high CO2). This may be normal operation and they
may not wish to show an alert.
• Lock Out Heat or Lock Out Cool (ISUs 6230, )
If the installer chose to lock out heat or cool on a custom Dry
Contact Alert condition, the T10+ will then ask if:
• You want a delay before the lockout (ISU 6600 or 6620).
For example, if someone was using a door sensor to
lock out cooling, you wouldn't want to short cycle the
cooling every time someone enters or exits. But if the
door is left open for a certain length of time, you may
wish to shut down the heat or cooling.
• If you still want a maximum temperature for cool (ISU 6610) or
minimum indoor temperature for heat (ISU 6630). Example: If
someone had a heat lockout configured when the window was
open, they left the window open, and the indoor temperature
dropped to 40°F, you probably still want the heat to run because
the danger of pipes freezing overrides the inefficient use of
heating with a window open
• Activate Fan (ISU 6230)
If selected, this setting turns on the fan when the selected custom
Dry Contact Alert (custom dry contact 1 through 4) is active.
• Activate Custom U terminal (ISUs 6230, 6240,
6250, 6260)
If you choose to activate a custom U terminal during a
custom alert, the T10+ will ask you to name the U terminals
used. That way the T10+ equipment status menu can show
what is being turned on or locked out. For example, you
33-00462—05
could wire a shut off valve to the U contacts and the status
would then show "Shut off valve energized" under equip-
ment status.
• Humidifier Lockout (ISU 8095)
If the T10+ and EIM are set for a custom Dry Contact Alert
and to control a humidifier, you can choose to lock out the
humidifier during a custom Dry Contact Alert (the Water
Leak Alert option also offers this setting).
• Dehumidifier Lockout (ISU 9145)
If the T10+ and EIM are set for a custom Dry Contact Alert
and to control a dehumidifier, you can choose to lock out
the dehumidifier during a custom Dry Contact Alert.
• Turn On Ventilator (ISU 10065)
If the T10+ and EIM are set for a custom Dry Contact Alert
and to control a ventilator, you can choose to turn on the
ventilator during a custom Dry Contact Alert.
• Lockout Ventilator (ISU 10140)
If the T10+ and EIM are set for a custom Dry Contact Alert
and to control a ventilator, you can choose to lock out the
ventilator during a custom Dry Contact Alert.

Battery Replacement

Indoor Sensor
BATTERY LEVEL INDICATORS
• Good: Status light flashes green for 5 seconds.
• Low: Status light flashes red for 5 seconds. Use
fresh batteries.
Battery level indicators (during use)
• Good: Status light remains off.
• Low: Battery power will be depleted in about 2
months.
Thermostat displays Low Battery warning. Status
light remains off.
• Critical: Battery power will be depleted in about 2–3
weeks. Status light flashes red.
BATTERIES
Replace batteries in your indoor sensor when a warning
appears on the thermostat screen, about 60 days before
batteries are depleted.
When the sensor status light begins flashing red, battery
power is critically low and will be depleted within 2–3 weeks.
During normal operation, the status light remains off.
To replace the batteries:
1. Remove the sensor from wallplate.
2. Install 2 fresh AAA alkaline batteries. If the status light
flashes green, batteries are good; if it flashes red, you
must use fresh batteries.
3. Attach sensor to wallplate.
The sensor will restore communication with the thermostat a
few seconds after new batteries are installed.
