Overview

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

The CM767/61NG is a sophisticated heating control system designed for residential use, offering advanced features for managing room temperature and hot water. It comprises a CM767/61NG Room Unit, which acts as the primary user interface, and a CM67G/60NG Relay Box, responsible for switching the boiler and hot water valve. The system is designed for ease of installation and user-friendly operation, with a focus on energy efficiency and comfort.

Function Description

The core function of the CM767/61NG system is to provide programmable time and temperature control for heating and hot water. The Room Unit allows users to set daily or weekly heating schedules, including different temperature settings for various times of the day. It features a large LCD display that shows current temperature, time, and operating mode, making it easy to monitor and adjust settings. The system supports multiple operating modes, such as Auto, Manual, and Off, providing flexibility to suit different user preferences.

The Room Unit communicates wirelessly with the Relay Box, which is typically installed near the boiler. This wireless communication eliminates the need for extensive wiring between the thermostat and the heating system, simplifying installation. The Relay Box receives commands from the Room Unit and activates or deactivates the boiler and hot water valve accordingly. It also provides visual feedback on its operational status through LED indicators.

A key feature of the CM767/61NG is its support for a Zoning System, allowing for independent temperature control in up to four different heating zones within a home. This is achieved by linking additional CM767/61NG Room Units to the primary system, each controlling a specific zone. This multi-zone capability enhances comfort and energy efficiency by heating only the areas that are in use.

The system also incorporates a "Party" mode, which allows users to temporarily override the programmed schedule for a set duration, maintaining a comfortable temperature during social gatherings. Similarly, a "Holiday" mode enables users to set a reduced temperature for an extended period when the home is unoccupied, saving energy without completely shutting down the heating.

Usage Features

The CM767/61NG Room Unit is designed for intuitive user interaction. The large LCD display provides clear information, and the navigation buttons allow users to easily access and modify settings. The programming interface guides users through the process of setting up heating schedules, making it straightforward to customize the system to individual needs.

For hot water control, the system offers a dedicated button to switch between Auto, On, and Off modes. In Auto mode, hot water is controlled according to a programmed schedule, while On mode provides continuous hot water, and Off mode disables it. This flexibility ensures hot water is available when needed, without unnecessary energy consumption.

The Room Unit features a "Temporary Manual Override" function, allowing users to temporarily adjust the temperature without altering the programmed schedule. This is useful for short-term comfort adjustments. The system also includes a "Fault Safe Mode," which ensures that the heating system continues to operate in a basic manner even if communication between the Room Unit and Relay Box is lost, preventing complete loss of heating.

The multi-zone capability is a significant usage feature, offering enhanced comfort and energy savings. Each zone can be programmed independently, allowing different parts of the house to be heated to different temperatures at different times. This is particularly beneficial in larger homes or homes with varying occupancy patterns.

The "Installer Set-Up Mode" provides advanced configuration options for installers, allowing them to customize various system parameters, such as cycle rates, minimum on-time, and sensor calibration. This ensures the system is optimized for the specific heating system and home environment.

Maintenance Features

The CM767/61NG system is designed for minimal maintenance. The Room Unit is powered by batteries, which are easily replaceable when the low battery indicator appears on the display. The system also features a "Service Interval" function, which can be programmed by the installer to remind users when the heating system is due for maintenance, ensuring optimal performance and longevity.

The Relay Box is a sealed unit with no user-serviceable parts, contributing to its reliability and requiring no routine maintenance. The wireless communication between the Room Unit and Relay Box is robust, but in case of communication issues, the system provides diagnostic information through LED indicators on the Relay Box and error messages on the Room Unit display, aiding in troubleshooting.

The "Fault Safe Mode" acts as a maintenance feature by providing a fallback in case of communication failure, ensuring basic heating functionality is maintained. This prevents a complete system shutdown and allows time for troubleshooting and repair.

The system's design emphasizes durability and long-term performance, with high-quality components and robust construction. Regular cleaning of the Room Unit's exterior with a soft, damp cloth is recommended to maintain its appearance. No internal cleaning or servicing is required by the user. In case of any malfunction or persistent issues, consulting a qualified installer or service technician is recommended.
