Product Description

The Honeywell Q979C1036 is explicitly identified as a Room Temperature Modulating Controller operating on $24V_{AC}$. It is generally a specialized device used in commercial or industrial HVAC systems, specifically for the control of terminal units like fan coils or air handling units.

The device’s function is to:

1. Monitor Temperature: It serves as the primary interface for sensing the ambient room temperature.

2. Setpoint Control: It includes controls (often adjustable via a remote) that allow users to set the desired temperature.

3. Modulating Output: It generates a modulating signal to control an actuator (e.g., a valve or damper actuator) in a proportional manner, such as $0-10V$ or $3$-position floating, rather than a simple On/Off signal. This proportional control provides more precise and energy-efficient temperature regulation.

4. Remote Sensor/Setpoint Functionality: It is frequently described as a “wall unit with remote” or a “remote sensor and setpoint module,” suggesting it provides an interface for users to adjust the settings and display the status, while the actual control logic is executed either within this unit or an associated main controller.

Product Specifications

Given its classification as a modulating temperature controller, the general specifications are:

Product Advantages

• Energy Efficiency (Modulating Control): By providing a continuous, proportional output, it prevents large temperature swings and allows the valve/damper to be positioned precisely, leading to significant energy savings compared to simple On/Off control.

• Superior Comfort: Modulating control maintains a tighter temperature band, resulting in improved occupant comfort.

• User Interface: As a wall unit, it offers an easily accessible and intuitive interface for building occupants or maintenance staff to monitor and adjust setpoints.

• Integration with HVAC Systems: Designed specifically for Honeywell’s portfolio of zone valves, dampers, and main building automation systems (BAS), ensuring seamless compatibility.

• Robust Construction: Designed for long-term use in commercial environments with durable plastic housing.

Precautions

• Voltage: Must be connected only to a stable $24V_{AC}$ power supply. Connecting to $120V_{AC}$ or $230V_{AC}$ will destroy the unit.

• Mounting Location: For accurate temperature sensing, the unit must be mounted on an interior wall away from direct sunlight, drafts, heat sources (lights, radiators), and cold spots.

• Wiring: All wiring must comply with local electrical codes and the manufacturer’s specific diagrams. Ensure proper terminal connection for power, output (actuator), and sensor inputs.

• Actuator Compatibility: Ensure the modulating output signal (e.g., $3$-position or analog) is compatible with the connected damper or valve actuator (e.g., Honeywell M6410 or similar).

• Calibration: Some units may require initial setup or offset calibration to ensure the displayed temperature accurately reflects the true room temperature.

Product Applications

The Q979C1036 is utilized where precise and localized temperature control is required within a larger building system:

• Commercial Office Spaces: Providing individual temperature control for different zones or offices within a floor.

• Fan Coil Units (FCUs): Controlling the motorized valve (modulating) that regulates the flow of hot or chilled water into the FCU heat exchanger.

• VAV (Variable Air Volume) Systems: Controlling a damper actuator to modulate the amount of conditioned air delivered to a specific room or zone.

• Hotel and Hospital Rooms: Offering guests or patients control over their immediate environment temperature.

• Zone Heating/Cooling: Serving as the control point for a specific climate zone in a commercial or industrial building.
