❓ Frequently Asked Questions (FAQ) Technical
💡 What is the main application of the CRA111 constant temperature control in underfloor heating?
In underfloor heating systems, constant control is vital to prevent overheating of the floor surface, protecting the materials (parquet, tiles) and ensuring maximum comfort. The CRA111 regulates the water mixture so that the supply flow rate remains precisely at the design temperature (e.g., 35ºC).
💡 How does torque affect 6Nm to the choice of valve?
The pair of 6Nm is sufficient to turn most ESBE VRG and VRB series mixing valves up to a nominal diameter (DN) of 50mmFor larger valves or high differential pressure systems, an actuator with higher torque should be considered.
💡 Is it necessary to isolate the included flow pipe probe?
Yes, it's essential. For the CRA111 to maintain reliable accuracy and temperature control, the flow probe must measure only the fluid temperature. The probe must be carefully isolated from ambient temperature to avoid false readings that could lead to incorrect valve regulation.
