Revision B
Window/Door Contact Sensor in myRoom Systems October 2019 to Turn Off Fan Coil Unit
This application note explains how to turn off an HVAC system and lock the myRoom Palladiom thermostat when a wired door or window contact sensor is opened.
For myRoom Prime systems, the window or door contact sensor will be connected to the CCI of the FCU Controller*. CCI is not supported for HVAC systems that do not use a SMC53 or SMC55 FCU controller. The instructions for configuring the CCI in a myRoom Prime system are on page 2 of this document.
For myRoom Plus system, the window or door contact sensor will be connected to the CCI of a QSE-IO. In myRoom Plus, CCI is supported for FCUs, VRV/VRF based HVAC systems and other HVAC systems over integration. The instruction for configuring a CCI in a myRoom Plus system are on page 5 of this document.
Instructions to use a CCI in myRoom Prime systems
Operation
When the door or window contact sensor opens, the FCU will turn off, and the myRoom Palladiom thermostat will lock out any button presses from being processed. The thermostat's backlights will flash with each button press to indicate the thermostat is locked. The FCU's ability to heat or cool will remain disabled, and the Palladiom thermostat will remain locked until the door/window contact sensor closes. While the window/door contact sensor is open, the fan will operate at a pre-configured speed.

Window/Door Contact Sensor Installation Connect the window or door contact sensor to the FCU controller, as described below: Step 1: Acquire a wired magnetic contact sensor (type SPST or SPDT). Step 2: Install the sensor to the window or door per the manufacturer's instructions. Step 3: Connect either lead of contact sensor to the white wire on the FCU Controller harness as shown in the first image below. Step 4: Connect the other lead to either of the 2 black wires on the FCU Controller harness. If multiple door or window sensors are used, wire the leads in series, so that any break in the line breaks the entire circuit as shown in the second image below.

Configuring the FCU Contact Closure Input (CCI)
Follow the "Thermostat and FCU controller Configuration Instructions" at www.lutron.com to set the following parameters. Refer to the Advanced Configuration Parameters. 1. Set advanced config parameter 64 (CCI type) to either 1 (Normally open) or 2 (Normally closed).
a. By default, it is set to 0 (disabled). 2. (Optional) Set advanced config parameter 65 (Open delay) in seconds to desired value. This value specifies the
required time in seconds after which the HVAC turns off when the window or door is opened. a. By default, it is set to 10 seconds. 3. (Optional) Set advanced config parameter 66 (Closed delay) in seconds to desired value. This value specifies the required time in seconds after which the HVAC turns on when the window or door is closed. a. By default, it is set to 1 second. 4. (Optional) Set advanced config parameter 67 (Open fan mode) to desired value. This value specifies the fan mode or speed for the FCU's fan after the time mentioned in advanced config 65 is elapsed. a. By default, it is set to 0 (OFF)
If the above values aren't available on thermostat or the CCI isn't working as expected, please check if the firmware requirement mentioned above is met by looking at the label on the top-right corner of FCU Controller as shown in image below.

Testing

Once the FCU CCI is wired and configured, it is recommended to test the setup.

Action Close the door or window to which the CCI sensors are attached and wait for the time specified in advanced config parameter 66. On the myRoom Palladiom thermostat press the fan button to toggle the fan speed.
On the myRoom Palladiom thermostat press the Power button to turn on the FCU. Open the door or window to which the CCI sensors are attached and wait for the time specified in advanced config parameter 65. On the myRoom Palladiom thermostat press the fan button to toggle the fan speed. On the myRoom Palladiom thermostat press the Power button to turn on the FCU.

Expected result No observable result.

Pass/Fail

On the palladiom thermostat screen, we can observe that the fan speed icon cycles from low speed, medium speed, to high speed. Note: Certain speeds may not be supported by the equipment and the equipment may remain in the supported fan speed.
Depending on the room temperature and the set point, the FCU will start to either cool or heat.
The FCU operation will switch to off from its previous state and fan speed will get switched to the speed specified in advanced config parameter 67.
The Palladiom thermostat display flashes and doesn't allow the fan speed to be changed.
The Palladiom thermostat display flashes and doesn't allow the Op Mode to be changed.

Troubleshooting
� If the Palladiom thermostat display flashes and doesn't allow changes, or if the HVAC doesn't turn on while the door is closed, ensure the correct CCI sensor type is programmed in advanced config parameter 64.
� If the HVAC does not turn off when the door is opened, ensure the correct CCI sensor type is programmed in advanced config parameter 64.

Operation When the door or window contact sensor wired to the CCI of the QSE-IO is opened, the HVAC equipment connected to the myRoom Palladiom thermostat will turn off and the thermostat will lock. The HVAC will remain off and the Palladiom thermostat will remain locked until the door/window contact sensor has been closed.

Window/Door Contact Sensor Installation
The window or door contact sensor must be connected to a QSE-IO CCI to use this feature. Follow the steps below.
� Acquire a wired magnetic contact sensor (type SPST or SPDT). � Install the sensor to the window or door per the manufacturer's instructions. � Connect either lead of contact sensor to the COM of the QSE-IO as shown in the figure below. � Connect the other end to any of the available CCI inputs as shown in the image below. The selected input will have to
be configured correctly to control the HVAC and lock/unlock the thermostat based on the CCI input.
If multiple door or window sensors are used, wire the leads in series, so that any break in the line breaks the entire circuit as shown in the second image below.
