D.System Controls and Wiring

1.Refer to National Electric Code or Local Electric Codes for proper size and type of wire required. Follow Code.

2.Use anti-short bushings on all wiring passing through boiler jacket, junction boxes and/or control boxes.

3.Use armored cable (BX) over all exposed line voltage wiring.

4.If an Alliance™ indirect water heater is used, use priority zoning except for Hydro-Air Systems.

5.Single Zone Heating System – Refer to Figure 30 of this manual for the electrical diagram for this type of system. Set the thermostat heat anticipator to 0.60 amps.

6.Single Zone Heating System with Alliance™ Water Heater - Refer to Figure 31 of this manual for the electrical diagram for this type of system.

Set the thermostat heat anticipator to 0.60 amps.

7.Conventional Circulator Zoned System – Refer to Figure 32 of this manual for the electrical diagram for this type of system.

Read, understand and follow all of the instructions provided with the Honeywell R8888 control.

Connect the thermostat of each zone and the circulator for that zone to R8888 panel. If an Alliance™ indirect water heater is used, connect the Alliance™ thermostat and circulator to the Zone 1 terminals of the R8888.

Set the thermostat heat anticipator to 0.12 amps.

NOTICE

The Honeywell R8888 Control is available in a three (3) z one Model (R8888A) and a four (4) z one Model (R8888B). Up to four (4) R8888's may be used together to provide control for up to twelve

(12)individual z ones. Only one (1) z one, the first z one of the main control, will provide priority circulation. If more than four (4) z ones are required, connect additional R8888's by wiring the A, B, and C terminals of each control together. Each R8888 requires a 120 volt power supply. If more than one (1) R8888 is used, set the panel type switch to "main" on the first R8888 and set the panel type switch to "expansion" on the second, third or fourth R8888.

8.Conventional Zone Valve Zoned System – Refer to Figure 33. Wiring to the most popular models of zone valves is given in Figure 34.

Connect the thermostat of each zone and the zone valve for that zone to the R8889 control. If an Alliance™ indirect water heater is used, connect the Alliance™ thermostat and zone valve to the “zone 1” terminals of the R8889.

Set the thermostat heat anticipator to 0.12 amps.

NOTICE

The Honeywell R8889 Control is available in two three (3) z one models and two four (4) z one models. Burnham recommends using Model R8889A for three (3) z one systems and Model R8889B for four (4) z one systems. Models R8889C and R8889D have less load capacity and may not operate with certain types of z one valves. Up to four (4) R8889's may be used together to provide up to sixteen (16) individual z ones. Only one (1) z one, the first z one of the main control will provide priority z oning for the Alliance indirect water heater. If more than four (4) z ones are required, connect additional R8889's by wiring the A, B and C terminals of each control together. Each R8889 requires a 120 volt power supply. If more than one (1) R8889 is used, set the panel type switch to "main" on the first R8889 and set the panel type switch to "expansion" on the second, third or fourth R8889.

SCG specifications

Burnham SCG, short for Burnham Smart City Grid, represents a groundbreaking initiative aimed at reshaping urban landscapes through the integration of modern technologies and sustainable practices. Situated in the heart of a growing metropolis, Burnham SCG embodies the principles of smart city design, focusing on creating an efficient, interconnected environment that enhances the quality of life for its residents.

One of the key features of Burnham SCG is its extensive use of Internet of Things (IoT) technology. This infrastructure enables real-time data collection from various sensors strategically placed throughout the city. For instance, smart streetlights equipped with sensors adjust their brightness based on ambient light conditions and pedestrian activity, effectively reducing energy consumption. This use of IoT extends to waste management, where smart bins signal when they are full, optimizing collection routes and minimizing fuel consumption.

In addition to IoT, Burnham SCG places a strong emphasis on renewable energy sources. The city integrates solar panels across public buildings and utilizes wind turbines in designated areas, contributing to a significant reduction in carbon emissions. Furthermore, an advanced battery storage system ensures that excess energy generated during peak production times is efficiently stored and used during high-demand periods, promoting energy resilience.

Transportation in Burnham SCG embraces the future with integrated smart mobility solutions. A robust network of electric vehicle charging stations encourages the adoption of eco-friendly transportation. The city also features a user-friendly app that provides real-time information about public transport schedules, bike-sharing availability, and traffic conditions, making it easier for residents to navigate their daily commute.

The urban design of Burnham SCG prioritizes green spaces and walkability. Urban planners have designed parks and pedestrian-friendly pathways that encourage outdoor activities and community engagement. These green areas not only enhance urban aesthetics but also contribute to improved air quality and biodiversity.

Lastly, community involvement stands at the core of Burnham SCG’s framework. The city regularly engages its residents through public forums and digital platforms, ensuring that their voices are heard in decision-making processes regarding urban development and sustainability initiatives.

In summary, Burnham SCG is a visionary model of a smart city that integrates technology, sustainability, and community engagement. With its innovative features and forward-thinking policies, it sets a benchmark for future urban developments around the world.
