Product Usage Instructions

Dry Contact Alerts
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.

Notifications

Water Leak Alert: When the dry contact device detects a water leak, the thermostat alerts the user.
System Shutdown Alert: A problem with the system was detected and it has been shut down. Contact your dealer for service.
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.
Dirty Filter Alert: When the dry contact device detects a dirty air filter (pressure drop across the filter), and the thermostat alerts the user to replace the filter.
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.
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.

Dry Contact Setup Example

Select the Dry Contacts in the System
Enable specific alerts such as Full Drain Pan Alert or Dirty Filter Alert

Dry Contact Alerts

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.
Dry Contact Setup Example
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 is 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 a 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 a 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 the 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
