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 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 and set operating times and control modes, ensuring a comfortable and energy-efficient experience for residential use.
Operation and Control modes
- The pump operates based on set operating times and temperature mode, with operating times taking priority. This means that the temperature mode can only be active during the specified operating times.
- LED indicators display the actual time (yellow), operating times (green), with the smallest time segment being 30 minutes.
- In the event of a power outage (such as a power cut or blackout), the pump will always retain selected operating periods. The current time setting is maintained for up to 8 hours. Once power is restored within this period, there is no need for the user to reset the time. Note: Units manufactured prior to production code PC 2523 do not include a power reserve for maintaining current time.
- When the temperature mode is enabled (indicated by a green temperature symbol LED), the pump measures water temperature during selected operating times. 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 12 hours during the first 15 minutes, allowing dynamic adjustment of ON/OFF temperatures.
