COMFORT pumps are efficient circulators designed for hot water recirculation in residential buildings.
These pumps feature a compact design housing and high-performance permanent magnet with an integrated control unit. The spherical rotor, equipped with an impeller, ensures optimal functionality, supported by a robust single-bearing ball system. The pump housing, crafted from drinking water approved brass, guarantees both safety and reliability.
Equipped with external and built-in temperature sensor, the COMFORT pumps provide precision in maintaining water temperature.
Installation is easy with included cable for electrical connection.
The user-friendly interface, made with LEDs and pushbuttons on the front, offers an intuitive platform to display control modes, ensuring a comfortable and energy-efficient experience for residential use.
Operation and Control modes
AUTOADAPT mode
- The pump constantly learns usage patterns throughout the day via an external sensor on the supply pipe and ensures hot water is available only when needed.
- During the first two weeks after installation, the pump frequently starts based on temperature control to ensure immediate comfort until usage pattern has been learned.
- After learning phase, pump operates only at times when hot water usage is predicted based on learned usage patterns. Pump operates based on temperature control in those predicted periods.
- After 24 hours of no water usage, the pump automatically enters vacation mode and resumes operation when it first detects demand for hot water.
- Once a week, when the highest water temperature in the system is detected, the pump runs a 15-minute legionella disinfection cycle. The water heater must have enabled that function once a week.
- The pump runs immediately when hot water is drawn off, at times usage pattern has not been yet learned and water temperature in pipes is cooled down.
TEMPERATURE+ mode
- When the temperature mode is enabled, the pump measures water temperature via an external and internal sensor. It automatically adjusts ON/OFF temperatures based on the maximum temperature measured in the system. For instance, if the maximum water temperature is measured at 113 °F (45 °C), the pump switches OFF at temperatures above 106 °F (41 °C) and turns back ON when the water cools down to below 100 °F (38 °C). The system's maximum temperature is measured every second.
- After 24 hours of inactivity, the pump automatically enters vacation mode and resumes operation when it detects demand for hot water.
CONTINIOUS 24/7 mode
- The pump operates continuously 24 hours per day.
