Solar controller GH26-P09 HSS0013

Advanced solar installation control

The GH26-P09 controller is a cutting-edge solution for the comprehensive management of solar installations. The device has been designed to handle practically every type of solar installation - from small domestic hot water heating systems to extensive installations supporting central heating or swimming pool water heating.

Functionality and system capabilities

The controller's advanced microprocessor technology enables the support of up to 6 NTC10kΩ temperature sensors, allowing for precise monitoring of the entire installation. The system simultaneously supports a maximum of 3 external devices - circulation pumps, control valves, or other heating system components. A special feature is the ability to control 2 electronic pumps using a PWM signal, which ensures optimal performance regulation.

The controller works with external heat sources such as heating boilers, calorifiers, or electric heaters, and also allows for the connection of 2 electronic flow meters to monitor the thermal efficiency of the installation. Additionally, the possibility of controlling system pressure is provided through the connection of a pressure switch, as well as cooperation with a UPS power supply to maintain the operation of the solar circulation pump.

Application area and configurations

The device supports a minimum of 19 solar installation diagrams, offering the flexibility to adapt to the specific needs of each facility. The system allows for the selection of the solar installation's operating priority - the priority can be set for domestic hot water heating, heating support, or swimming pool water heating.

Functionality also includes time programs for circulation pumps and individual settings for the intermittent operation of the domestic hot water circulation pump (so-called short-cycling). Particularly important is the hygienic function implementing periodic thermal disinfection (anti-legionella), which ensures the safe use of the installation.

Operating conditions and device characteristics

The controller is powered by 230V/50Hz with a power consumption of only 1.5W, making it an energy-efficient solution. The device is characterized by a high protection rating of IP65, guaranteeing resistance to environmental conditions in boiler rooms and technical rooms.

The system operates in an ambient temperature range from 0°C to +60°C (according to some sources up to +40°C) with a relative humidity of up to 85% at 25°C. Compact dimensions (160×110×45mm) and wall mounting allow for easy installation anywhere.

The touch panel with a clear LCD graphic display provides intuitive operation and real-time system monitoring. The built-in real-time clock enables precise operation planning even after power disconnection.
