The TCS Basys Controls CQ1101 MIN/MAX POSITION MODULE is a critical component for technicians managing HVAC analog signal conditioning in complex building automation systems. This module allows for precise field adjustments of 0-10VDC or 4-20mA control signals, effectively overriding or limiting the range of a master controller. By setting hard floor and ceiling values, you prevent downstream actuators from moving into inefficient or mechanically straining positions, ensuring BAS system stability. Its compact design facilitates easy mounting within existing enclosures, making it a go-to for VAV box signal limiting and damper position control. The CQ1101 module is engineered for seamless integration with TCS Basys Superstat and UbiquiSTAT series controllers. Built for reliability in commercial HVAC control environments, this hardware simplifies proportional signal adjustment without the need for complex software reprogramming in the field. Use it to maintain minimum ventilation rates or protect equipment from over-travel during modulating actuator installation. Key Benefits Provides hardware-based analog signal limiting to ensure actuators stay within safe mechanical bounds. Compatible with standard 0-10VDC and 4-20mA HVAC signals for universal application in commercial control loops. Simplifies minimum outdoor air requirements by locking in a physical minimum damper position. Reduces wear and tear on modulating valve actuators by preventing oscillation at extreme signal ranges. Seamlessly bridges the gap between master BAS controllers and field-mounted proportional devices. Common Questions How do you calibrate the CQ1101 for a specific signal range? Technicians use the onboard potentiometers to trim the minimum and maximum output limits while monitoring the signal with a standard digital multimeter. This physical adjustment provides a reliable analog signal override that persists regardless of software updates. Is the CQ1101 compatible with third-party HVAC actuators? Yes, the TCS Basys CQ1101 is designed to work with any HVAC actuator that accepts a standard proportional 0-10V or 4-20mA input, making it highly versatile for multivendor BAS integration. Where should the min/max module be installed in the control loop? The module should be wired in series between the master controller output and the actuator input. This allows the CQ1101 module to intercept and modify the signal based on your predefined physical limits.
