DESCRIPTION

The 95A03-TWH Thermostat Display Control (TDC) is designed to be used with Leviton’s 65A60-1 TDC Communication Interface and an Omnistat2 RC-2000 series thermostat as an easy-to-access interface. Leviton’s RC-2000 series thermostats can control both single and multi-stage HVAC systems, and are available using either hardwired communication or ZigBee wireless. The TDC can be flush mounted on a wall for a clean and attractive appearance. It can be used to select the desired temperature, adjust fan and mode settings, and more. The TDC has a built-in temperature sensor that can be averaged with up to 3 other TDC sensors and/or the sensor in the RC-2000 thermostat. Temperature averaging ensures precise reading and automation for comfort and enhanced energy efficiency

Required Components:

• Model 65A60-1 TDC Communication Interface
• Omnistat2 RC-2000 series thermostat with firmware Version 1.05B or later

INSTALLATION

The (TDC) connects directly to a TDC Communication Interface (65A60-1) using Cat 5, unshielded, twisted pair (UTP) for communications. Each end of the wire is terminated with an RJ45 connector. The correct wiring scheme for the Cat 5 cable is standard EIA/ TIA 568A. Properly terminating the Cat 5 cable is crucial for the operation of the system. The total distance of Cat 5 between the TDC and TDC Communication Interface not exceed 1500 feet. Insert the RJ45 connector on one end of the cable to the jack labeled U2 on the TDC Communication Interface. Insert the RJ45 connector on the other end of the cable to the jack on the TDC. A maximum number of 4 TDC keypads can be connected to a TDC Communication Interface.

CONFIGURING THE TDC
After the TDC and TDC Communication Interface have been installed and connected, there are several installation settings on the RC-2000 thermostat that need to be configured.

The Temperature Sensor settings are used to configure the internal temperature sensor, optional remote temperature sensor, and temperature sensor in the TDC. Any temperature sensors that are set as the same type (i.e. indoor or outdoor) will display the average temperature reading among the sensors.

• Internal Sensor: This will enable or disable the onboard temperature sensor for indoor use only. *Enabled
• External Sensor 1: This will enable the external temperature sensor for indoor or outdoor use. All indoor and outdoor temperatures are averaged between all sensors of the same type. *Disabled
• External Sensor 2: This will enable the expansion module temperature sensor for indoor or outdoor use. All indoor and outdoor temperatures are averaged between all sensors of the same type. *Disabled
• TDC Sensor: This will enable the expansion module temperature sensor for indoor or outdoor use. All indoor and outdoor temperatures are averaged between all sensors of the same type. * Disabled

WARNINGS AND CAUTIONS

• Do not use this product near water – e.g., near a tub, wash basin, kitchen sink or laundry tub, in a wet basement, or near a swimming pool.
• Never install communications components in wet locations unless the components are designed specifically for use in wet locations.
• Use caution when installing or modifying communications wiring or components.

By default, the RC-2000 is configured to only display the temperature of its internal temperature sensor on the TDC. To average the internal sensor in the RC-2000 with the temperature sensor in the TDC, set the Internal Sensor to “Enabled” and the TDC Sensor to “Indoor”. To use only the temperature sensor in the TDC, set the Internal Sensor to “Disabled” and the TDC Sensor to “Indoor”.

Note: when multiple TDC keypads are connected to the TDC Communication Interface and if the TDC Sensor is set to “Indoor”, then all of the temperature of each of the temperature sensors in the TDC keypads will be averaged together

• By default, the RC-2000 is configured to only display the temperature of its internal temperature sensor on the TDC.
• To average the internal sensor in the RC-2000 with the temperature sensor in the TDC, set the Internal Sensor to “Enabled” and the TDC Sensor to “Indoor”.
• To use only the temperature sensor in the TDC, set the Internal Sensor to “Disabled” and the TDC Sensor to “Indoor”.

TDC Options
To configure the Periodic Flash and Eco Mode setback options for the TDC:

• From the Installation Settings menu, turn the Scroll Wheel until “TDC Options” is highlighted.
• Press the Scroll Wheel or [Select] to select “TDC Options”.

Periodic Flash
When Periodic Flash is sent to “Off” (default setting), one minute after that last time a button is pressed on the TDC keypad, the display on the TDC is turned off. The display will remain off until a button is pressed on the TDC keypad. When a button is pressedon the TDC keypad, the display is turned back on for one minute. When Periodic Flash is set to “On”, the TDC display is turned on and the temperature is displayed every ten seconds. After displaying the temperature for three second, the display is turned off for ten seconds. Whenever a button is pressed on the TDC keypad, the display is turned on for one minute.

Eco Mode Setback
Eco Mode is used to quickly setback the heat and cool setting of the RC-2000 thermostat for energy savings. The TDC can be used to set the RC-2000 to Eco Mode when leaving the premises, and then restored to normal upon returning. The number set for the Eco Mode Setback option is the number of degrees that the heat and cool setting will be setback whenever the TDC is set to Eco Mode. The default setting is 4 degrees.

CHANGING THE COLOR OF THE TDC
The color of the TDC may be changed to complement the interior décor. The TDC is supplied with a white faceplate, rubber keypad, and insert. Additional colors are available; contact your Leviton distributor for more information. Change the color of the TDC as follows:

• Remove the faceplate.
• The insert attaches to the TDC with two latches on the right and two on the left.
• Using a small-blade screwdriver, gently depress each latch on one side while lifting up on the insert. Once the latches are released on one side, remove the insert from the other side.
