Frequently Asked Questions
What thermal output does the HC - AC provide?
See "Thermal power" in the table: typically 10-100 kW at nominal water temperature.
The declared power refers to water at 80°C supply and 60°C return with an ambient temperature of 15°C. For different conditions, the output varies proportionally.
What room volume is it sized for?
See the recommended volume data: typically 200-2,000 m³ depending on the model.
Sizing depends on the building's insulation, heat losses, and minimum outdoor temperature. Consider a 20% margin on the nominal calculation.
What hydraulic system does it require?
Connection to a hot water circuit with shut-off and balancing valves.
Installation with ball valves, a Y-strainer at the inlet, and a bleed valve on the flow line is recommended. Max operating pressure indicated in the technical table.
Is the fan speed adjustable?
Modern models offer EC motors with continuous regulation, while traditional ones have 2-3 fixed speeds.
EC motors consume up to 60% less and allow for fine modulation. They are recommended for installations in residential or commercial environments.
What electrical connection does it require?
See "Voltage" and "Power consumption" of the motor: typically 230 V single-phase for small models, 400 V for large models.
Models with EC motors require shielded cables and connection to the control system (0-10 V or digital signal).
