Introduction to the Green Box T+H

The Munters Green Box T+H is designed to enhance temperature and humidity measurement in greenhouses and other applications where accurate data is required, especially when solar radiation or microclimates can influence readings.

Components of the Green Box:

• Plastic enclosure connected to a cable
• 6-wire cable
• Fan
• Temperature and humidity sensor

Included Accessories:

• Connection Box, connected via a 10.5-meter 6-wire cable
• 5-meter chain (attached to the Green Box cable)
• S Hook
• Two mounting brackets
• Two roundhead screws (for attaching brackets to the Connection Box)
• Two flathead screws (for attaching brackets to a wall/wood sheet)

2.1 Green Box Positioning

Position the Green Box in a representative location, choosing a spot not vulnerable to damage. Avoid placing it too close to heaters or pathways.

• For short crops, position the Green Box approximately 30 cm (12 inches) above the crop, in an area minimally influenced by metal objects or other factors like paths or sprayers.
• For tall crops, position the Green Box around the middle of the crop height, in an area similarly free from undue influence from metal objects or other environmental factors.

2.2 Green Box Installation

1. Hang the Green Box in the desired location using the supplied chain and S hook.
2. Install the Connection Box using the supplied clips in the required location. CAUTION: Ensure the Connection Box is installed within 10.5 meters of the Green Box.
3. NOTE: When placing the Green Box in high positions (e.g., tall crops), leave sufficient cable slack for maintenance access.
4. The Green Box and Connection Box come with pre-installed wiring. The user must connect the Connection Box to the controller's analog input card and power supply.
5. CAUTION: Do not use electrical cable for hanging the unit.

2.3 Green Box Connection Specifications and Wiring

The Green Box is wired to the controller via a 6-wire shielded cable with the following connections:

• 24 VAC for the fan
• 24 VAC for the fan
• Temperature output
• Relative humidity output
• 12 VDC for the RH sensor
• Common

Wiring and Connections

Figure 3: Green Connection Box - Controller RAIC11 wiring (example) illustrates the connection of the Green Box to a controller. The RTS Temperature Sensor and RHS+ Humidity Sensor can be connected to any RAIC11 input port.

• The cable shield should be connected to ground on one side only.
• The Green Box Connection Box is prewired to the sensors; these wires are not shown in Figure 1.
• Refer to Figure 4 for an expanded view of the jumpers.
• Refer to Figure 5 for details on fan power supply.

Wiring Terminal Descriptions:

• COM Ports
• 12 Volt Port (Humidity Sensor)
• SIGNAL PORTS (Temperature or Humidity Sensor)
• 5 Volt

Diagram Description (Figure 4: Jumpers - Expanded): Shows input terminals (INPUT1-INPUT11) on a controller board with jumper settings for different sensor types (TEMP, 0-5V, 4-20mA, WIND).

Diagram Description (Figure 5: Powering the Fan): Depicts a transformer (115/230 VAC input) providing 24 VAC power to the Green Connection Box, with connections for the fan.

Maintenance

Periodically inspect the fan for excessive dust buildup.

3.1 Temperature Sensor

The temperature sensor requires no maintenance.

3.2 Humidity Sensor Replacement

This procedure describes how to replace the humidity sensor head assembly:

1. Unscrew the box tip to locate the humidity sensor. Diagram Description (Figure 7: Box tip removed): Shows the sensor housing with its protective tip removed.
2. Untwist the filter. Diagram Description (Figure 8: Filter): Shows the filter component.
3. Pull out the sensor assembly. Diagram Description (Figure 9: Sensor assembly): Shows the sensor assembly, comprising a sensor element and a sensor tip. CAUTION: Do not touch the sensor element.
4. Remove the Sensor Tip. Diagram Description (Figure 10: Sensor Tip): Shows the replaceable sensor tip.
5. Install a new Sensor Tip and replace the filter. NOTE: Insert the Sensor Tip gently, ensuring pins are fully seated. If it does not fit, pull it out, turn it over, and reinsert.

3.3 Fan Replacement

Diagram Description (Figure 11: Unit fan): Shows the fan unit within the Green Box housing.

1. Disconnect the fan's red and black wires from their connectors.
2. Unscrew the fan, remove the old unit, and install the new unit.
3. Connect the fan's red and black wires to the wire connector:
• Black wire connects to the connector opposite the blue wire.
• Red wire connects to the connector opposite the brown wire.

3.4 Fuse Replacement

The Connection Box is equipped with a 160 mA fuse. A spare fuse is provided in a small plastic bag.

Diagram Description (Figure 12: Fuse location): Shows the location of the fuse within the Connection Box terminals.

1. Disconnect the Connection Box's power supply.
2. Open the box, remove the old fuse, and replace it with the spare.
3. Close the box and reapply power.
