Description

Salus NPC1 Electronic Controller for Heating Circulation Pumps

The Salus NPC1 is a compact and efficient electronic controller designed to automatically manage the recirculation pump in central heating systems (ideal for solid fuel, wood, or coal boilers without built-in automation). By starting and stopping the pump based on live temperature readings, it optimizes energy consumption and protects the boiler from low-temperature corrosion.

Key Features & Operation

• Automated Temperature Control: Measures boiler temperature and activates the circulation pump once your set temperature threshold is reached.

• Smart Shutdown: Automatically stops the pump when the fire dies down and the temperature drops below the set point (with a fixed 2°C hysteresis), preventing cold water from circulating and saving electricity.

Advanced Safety Features

• Anti-Stop Function: Prevents the pump rotor from seizing during long periods of inactivity (e.g., during summer) by periodically running the pump for brief intervals.

• Anti-Freeze Protection: Automatically activates the pump if the sensor detects temperatures below 5°C to protect pipework and prevent freezing.

• Overheat Alarm: Sounds an audible alert if the heating medium temperature exceeds the 90°C safety threshold.
