Applies to the following Model Numbers:
YTHM1004R3000: Kit with T10+ Thermostat, EIM, Wireless Indoor Sensor, & Wired Discharge and
Return Sensors
YTHM1004R3001: Kit with T10+ Thermostat, EIM, Wireless Indoor Sensor, wireless outdoor sensor, &
Wired Discharge and Return Sensors
A Dry Contact device such as a wet switch can be connected
to the S1, S2, S3, or S4 terminals at the Equipment Interface
Module. When the dry contact device detects a problem, the
thermostat displays an alert on the home screen along with the
dealer information.
When the user presses the alert for more information, the
notification screen is displayed, prompting them to contact
their dealer.
The following dry contact alerts are available for the T10+
with EIM:
Full Drain Pan Alert
When the dry contact device detects that the condensation
drain pan is full, the thermostat provides an alert to the user.
NOTE: When a full drain pan alert is selected, there is a follow
up setting asking if you want to shut off the system when
this alert is active or just send the alert message.
Dirty Filter Alert
When the dry contact device detects a dirty air filter (pressure
drop across the filter), the thermostat alerts the user to replace
the filter.
Water Leak Alert
When the dry contact device detects a water leak, the thermostat
alerts the user.
NOTE: When a water leak alert is selected, and the T10+ is
configured to control a humidifier there is a follow up
setting asking if you want to shut off the humidifier when
this alert is active or just send the alert message.
System Shutdown Alert
When the dry contact device detects a critical problem with
the system, the thermostat alerts the user that the system was
shut down. When the dry contact device detects a problem with
the system (for example, smoke detection), the thermostat will
not call for heating, cooling, fan or IAQ equipment until the dry
contact is deactivated or the feature is no longer configured at
the thermostat.
Service Needed Alert
When the dry contact device detects an issue that requires
service, the thermostat provides an alert to the user.
Fan Failure Alert
The Fan Failure Alert protects the equipment when there is no
airflow. When the dry contact device (for example, sail switch)
detects no airflow for 5 minutes after a call for forced air heat,
cool, or fan, the thermostat alerts the user that the system was
shut down due to a lack of airflow. The thermostat will call for the
fan and lock out all other equipment until the dry contact device
senses air flow again or the feature is no longer configured at
the thermostat.
Custom Alert
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.

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, 6340, 6440,
6540)
If the installer previously 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 (ISUs 6230, 6340, 6440, 6540)
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, 6340, 6440,
6540)
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 could wire a shut off valve to the U contacts and the
status would then show “Shut off valve energized” under
equipment 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

NOTES:
• For this file, only the dry contact ISU settings are shown. Full ISU settings are found in the product
data sheets located at : https://customer.resideo.com/resources/Techlit/TechLitDocuments/33
00000s/3300462.pdf.
• The firmware is occasionally updated over the air (OTA) from the factory. To ensure the latest firmware
updates are installed, confirm the thermostat is connected to a stable WiFi connection. Some ISU
settings may not be shown on models that don’t have the latest firmware.
