Two HVAC monitoring configurations are available now. Both connect with MCerberus monitoring; the MCB-414A adds filter differential-pressure monitoring.
HVAC Monitoring System
Core HVAC equipment monitoring with three temperature sensors, blower current sensing, and water sensor options.
HVAC Monitoring System with dP Filter Monitoring
Includes the core monitoring configuration with differential-pressure filter monitoring.
The 24VAC-001 transformer supplies power from a standard outlet for Wi-Fi setup away from the equipment or the simplified homeowner installation. Thermostat signal sensing is not available in this power configuration; the simplified installation uses Delta P sensing for ON/OFF detection.
Setup note: System functions depend on selected model, sensor configuration, installation method, and network access. Review the product documentation before purchase and installation.
MCerberus® monitors thermostat signals alongside equipment measurements to help identify when system operation does not match the thermostat’s request.
Thermostat signals are the preferred method for detecting equipment ON/OFF state. Connections are optional: other supported methods include blower current and Delta P sensing, depending on installation and configuration.
Isolation relays on thermostat signal inputs help distinguish true thermostat calls from thermostat outputs with leakage current when OFF, reducing false ON indications.
Current hardware detects reversing valve operation indirectly to help distinguish heating and cooling operation.
Planned for the next board: direct reversing valve signal measurement through the orange wire.
