Optimized Heat Pump linkage for integrated FCU and radiant floor heating control.

Engineered specifically for Air-to-Water Heat Pump systems, this solution integrates smart thermostats with a centralized wiring center to synchronize FCU cooling and underfloor heating. The system manages the heat pump’s operational cycles and mode switching via universal volt-free contacts, while incorporating optional PICVs to achieve dynamic hydraulic balancing, ensuring maximum COP (Coefficient of Performance).

Solution Diagram

The smart thermostat monitors ambient loads to coordinate the central wiring center. Based on real-time demand, the center signals the Heat Pump’s on/off status via universal volt-free contacts while managing fan speeds and thermal valves. The optional PICV maintains a constant flow rate across all loops, protecting the heat pump from pressure-related cycling and ensuring stable water temperatures.

FAQ

Yes. Our solution utilizes universal volt-free (dry contact) linkage, making it compatible with 99% of air-to-water heat pump brands. It provides a reliable bridge between your high-end indoor control logic and the heat pump’s basic on/off coordination.

Our smart wiring center features integrated delay logic and multi-zone demand aggregation. The heat pump is signaled to start only when there is a verified thermal load, and it remains operational for an optimized period to ensure system stability and extend equipment service life.

Yes, that is our core strength. For our Smart HMI platforms, we offer a fast-track design service. From UI prototype confirmation to firmware readiness, we can complete the branding and interface customization within 7 days to help you reach the market faster.

A PICV ensures a constant flow rate in each loop regardless of pressure fluctuations in the pipe network. It eliminates hydraulic imbalance, prevents over-flow noise, and ensures that the heat pump operates at its highest COP (Coefficient of Performance).

The system is designed with sophisticated synergy logic. It prevents thermal conflict by intelligently switching between modes—utilizing FCUs for rapid cooling/dehumidification and underfloor loops for silent, comfortable heating, ensuring premium indoor climate control.

Absolutely. Our controllers and wiring centers are ready for Modbus and BACnet protocol integration, allowing seamless communication with higher-level smart building platforms and remote monitoring systems.
