Product Description

The Braemar CQS PCB Circuit Board ICS 2 Stage Triac Gas Ducted Heater with part number 651972 is an important electronic component used in specific models of Braemar gas ducted heaters, such as those in the CQS series. Here’s a detailed description of what this component is and its function:

Key Components and Functions:

PCB Circuit Board (Printed Circuit Board):
- The PCB is the central control board for the gas ducted heater, responsible for managing the various electrical functions of the system.
- It is often referred to as the "brain" of the heater since it controls things like ignition, heating stages, fan operation, and safety features.
ICS (Integrated Control System):
- ICS refers to the integrated control system built into the PCB that coordinates the operation of the heating system. It ensures that the system runs smoothly and efficiently by controlling different stages of operation based on input from sensors.
2-Stage Triac:
- A Triac is a type of semiconductor device used for switching and controlling the electrical current in the system.
- The 2-stage feature means the heater operates with two different levels of heating power (often "low" and "high" stages). This allows the heater to efficiently regulate the temperature of the room, providing a balance between energy efficiency and effective heating.
- The Triac is responsible for managing the switching between these stages, ensuring smooth transitions and proper heating control.

Functions:

Ignition Control: The PCB manages the ignition process by sending signals to the spark igniter and flame sensor, ensuring the heater turns on safely.
Temperature Regulation: The board processes input from the thermostat and temperature sensors to maintain the desired indoor temperature. It adjusts the gas flow and fan speed based on the system's set points.
Safety Monitoring: The PCB controls the safety systems, including detecting flame failure (via the flame sensor), overheating protection, and preventing gas leakage. If any of these conditions occur, the board will trigger the necessary safety mechanisms, such as shutting off the gas supply.
2-Stage Heating Control: With the 2-stage functionality, the PCB controls how much gas and power is used at each stage. This optimizes heating for different conditions, like maintaining a constant temperature in mild conditions or providing higher heat output when needed.
Fan and Motor Control: The PCB also manages the fan motor that circulates the air throughout the space, ensuring that airflow is consistent and proper for optimal heating.

Importance:

This circuit board is essential for the overall functioning and efficiency of the Braemar gas ducted heater. If the PCB fails, the heater may not ignite, the fan may not operate, or the system might not regulate heat properly, leading to poor performance or safety hazards.
Replacing the PCB is often necessary when the heater experiences issues with control, ignition, or when certain functions stop working, such as temperature regulation or switching between heating stages.

Usage:

The 651972 PCB Circuit Board is specifically designed for the Braemar CQS gas ducted heater series. It ensures compatibility and reliable performance when replacing or upgrading the control system.
It’s advisable to have a qualified HVAC technician or professional repair person replace or troubleshoot the PCB if there are issues, as this component is critical to the system's operation and safety.

If you're experiencing issues like the heater not igniting, failing to heat properly, or cycling inappropriately, the PCB Circuit Board (651972) might need to be replaced. Always follow safety procedures when working with electrical components.
