## Summary description

Hewalex MiniSOL HSS0001 is a solar controller designed for solar thermal collector systems. It monitors and controls basic operation of collectors and circulation pumps, enabling temperature-based pump activation and protection of the installation. Suitable for small domestic solar hot-water or heating support systems and for integration with existing pump and sensor setups.

## Long description

Hewalex MiniSOL HSS0001 for solar thermal systems is a compact electronic controller intended to monitor and manage the basic operation of solar thermal collector installations. The unit measures temperatures from collector and storage sensors and switches the circulation pump according to set temperature differentials, providing automatic activation and deactivation of the pump to transfer heat from collectors to storage. Designed for small domestic solar hot-water or heating support systems, the controller integrates with external pumps and temperature sensors and provides essential protection for the installation against overheating or reverse circulation.
Advantages
The controller offers a compact design and straightforward temperature-based control logic that simplifies integration into existing systems. It enables reliable automatic pump switching based on measured temperature differences, supports protection functions to prevent undesirable operation, and requires minimal configuration for standard solar thermal setups. The device is suitable for installations where basic, dependable control of collectors and circulation pumps is required without complex features.
Suitable for
 Small domestic solar hot-water systems
 Solar-assisted heating support for single-family homes
 Retrofit or integration with existing circulation pumps and sensors
 Basic collector installations requiring temperature-differential pump control
Key specifications
 Function: temperature-differential control for solar thermal collectors and circulation pump
 Inputs: connections for collector and storage temperature sensors
 Output: pump control relay for switching circulation pump
 Control logic: automatic pump activation/deactivation based on set temperature difference
 Protection features: prevents pump operation under inappropriate temperature conditions
 Application: designed for small domestic solar hot-water and auxiliary heating systems
 Installation: integrates with external pumps and sensors; compact housing for simple mounting
How to use
Install the Hewalex MiniSOL controller according to the system layout: connect the collector sensor to the dedicated input and the storage (tank) sensor to the storage input, wire the circulation pump to the pump control output, and supply power following electrical safety requirements. Configure the temperature differential thresholds as needed for the specific installation so the pump starts when collector temperature exceeds storage temperature by the set value and stops when the differential drops below the release point. Verify sensor placement and system hydraulics before first operation and monitor initial cycles to confirm correct switching behavior.
Usage recommendations
Place temperature sensors in representative locations: the collector sensor on the absorber or flow pipe and the storage sensor near the upper part of the hot-water tank. Use appropriate weatherproof sensor placement on the collector and ensure secure electrical connections. For reliable long-term operation, pair the controller with compatible sensors and pumps, follow manufacturer installation guidelines, and perform periodic checks of sensors, wiring, and pump operation.
