INSTALLATION
NOTE: INSTALL IN COMPLIANCE WITH ALL APPLICABLE CODES & STANDARDS.
Failure to follow these instructions may cause personal injury or equipment damage.
The DCLV2 is a Class 2 product. A low voltage cable with the appropriate number of conductors must be installed. For ease of
installation, manufacturer recommends use of a deep wall box.
1. Disconnect power to circuit by turning circuit breaker OFF before installation.
2. Remove the existing wall plate and switch, if one is present. If there is an existing line voltage switch the wiring must be converted
to low voltage in order to use the origina
l wall box location for the DCLV2. Alternatively, the existing line voltage switch may
remain, however a new wall box must be installed for the DCLV2 according to NEC requirements.
3. Install power pack to control the desired lighting circuit.
4. Strip existing wires 1/4”. If two wires will be connected to the same terminal, both wires must be the same gauge. Connect wires
as appropriate for your application. See the wiring diagrams on the following page.
5. Attach the wall plate.
6. Switch the circuit breaker bac
k ON.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Wattstopper Decorator Style 0-10V Controller, model DCLV2, is a wallbox controller designed for managing 0-10V dimming systems. It offers both Manual On and partial Auto On functionalities, providing flexibility in how lighting is controlled. This device is specifically engineered to work in conjunction with Wattstopper BZ Series power packs and can be integrated with occupancy sensors for enhanced automation.

Function Description

The DCLV2's primary function is to control electronic ballasts and drivers for LED lighting systems. It achieves this by sinking up to 50mA, which allows it to manage up to 100 ballasts wired in parallel, assuming each ballast sources 0.5mA. The 0-10V output range of the DCLV2 operates at a minimum of 0.75VDC and a maximum of 9.5VDC, providing precise dimming control. It is a Class 2 device, receiving its operating supply voltage of 24VDC directly from an external source, specifically a Wattstopper BZ series power pack for 0-10V ballast control. The controller is also capable of receiving input from a sensor, enabling automated responses based on occupancy or vacancy.

The DCLV2 supports low-voltage DC dimming using Class 2 wires, allowing multiple circuits to utilize the same dimming signal without requiring additional power equipment. It executes a straight proportional relationship between the internal dimming level and the voltage provided, ranging from 0.6VDC to 9.5VDC.

When operating with an ON/OFF option, the DCLV2 integrates relay control. As the user ramps up the dimming level, relay 1 output switches from 0V to 24VDC, closing the power pack relay to supply line voltage to the light fixtures. Conversely, when the user ramps down and the 0-10V output reaches 0V, relay 1 switches to 0V, opening the power pack relay and removing power to the light fixtures. This allows for a smooth ramp-down of the ballast before it turns OFF. It's important to note that an ON to OFF transition may take approximately 2 seconds due to the dimming-down process, while an OFF to ON transition is immediate.

Usage Features

The DCLV2 offers several user-configurable operating modes to suit different preferences and applications. By default, the device is in Manual On mode, with Auto On disabled.

To enable Auto On mode:

1. The user presses and holds both the top and bottom of the paddle for two seconds to enter LEARN mode.
2. After releasing the paddle, the user presses and holds the RAISE button for two seconds. The device confirms the new mode by flashing its LED red for 1.5 seconds.
3. Finally, the user presses and holds LEARN again for two seconds to exit setup and return to normal operation.

To switch back to Manual On mode:

1. The user presses and holds both the top and bottom of the paddle for two seconds to enter LEARN mode.
2. After releasing the paddle, the user presses and holds the LOWER button for two seconds. The device confirms by flashing its LED green for 1.5 seconds.
3. The user presses and holds LEARN again for two seconds to exit setup and return to normal operation. A convenient feature for both Manual On and Auto On modes is that if the top of the paddle is momentarily pressed when the load is already ON, the load will immediately go to 100%.

The DCLV2 also incorporates a Partial On mode. By default, when a sensor triggers occupancy, the DCLV2 sets the load to the dimming level it was at when Manual On or Auto On was enabled. This is referred to as Partial On. To set a fixed value for Partial On:

1. The user presses and holds both the top and bottom of the paddle for two seconds to enter LEARN mode.
2. After releasing the paddle, the user uses the paddle to set the desired dimming level.
3. The user presses and holds LEARN again for four seconds to exit setup and return to normal operation. By default, or after a reset, Partial On is enabled with a fixed value of 50%.

To disable the Partial On feature, there are two methods: Method 1:

1. Turn OFF the Load.
2. Press and hold both the top and bottom of the paddle for two seconds to enter LEARN mode.
3. Release the paddle.
4. Press and hold LEARN again for four seconds to exit setup and return to normal operation. Method 2:
5. Press and hold both the top and bottom of the paddle for two seconds to enter LEARN mode.
6. Release the paddle.
7. Press the bottom of the paddle until the load is off.
8. Press and hold LEARN again for four seconds to exit setup and return to normal operation.

The Retrigger Mode is another useful feature. When in Manual On mode, if a connected sensor registers a vacancy and turns the load OFF, an automatic 30-second retrigger mode is enabled. If the sensor registers occupancy during this period, the load will return to its previous level. After the 30-second retrigger period, subsequent occupancy registrations will cause the load to respond based on the Manual On or Auto On setting configured for the DCLV2.

Maintenance Features

For maintenance or troubleshooting, the DCLV2 can be reset to its factory defaults. The factory default setting for the DCLV2 is Manual On with Partial On enabled at 50%. To perform a reset:

1. The user presses and holds both the top and bottom of the paddle for 10 seconds.
2. The green LED will blink, and the lights will turn off, indicating that the reset is complete.

Installation of the DCLV2 requires adherence to all applicable codes and standards to prevent personal injury or equipment damage. As a Class 2 product, it requires a low voltage cable with the appropriate number of conductors. For ease of installation, the manufacturer recommends using a deep wall box. Before installation, power to the circuit must be disconnected by turning the circuit breaker OFF. Any existing wall plate and switch should be removed. If a line voltage switch is present, the wiring must be converted to low voltage for the DCLV2, or a new wall box installed according to NEC requirements. After installing the power pack to control the lighting circuit, wires should be stripped 1/4 inch. If two wires are connected to the same terminal, they must be of the same gauge. After connecting wires as appropriate for the application, the wall plate is attached, and the circuit breaker is switched back ON.

The DCLV2 is designed to be compatible with any BZ series power pack. However, specific considerations apply: the Orange, Brown, and Gray wires on the BZ-150 and BZ-250 power packs are not used and should be capped. The Manual/Auto On switch on the BZ-150 and BZ-250 should be left in the Auto-On position, as manual functionality is handled by the DCLV2. Additionally, the BZ-200 and BZ-250 must be grounded to ensure signal integrity, not for safety ground. For simple ON/OFF control systems, the 0-10V output on the DCLV2 should not be connected.
