Universal controller for heap pump UKTN-1 is hardware&software control system designed for be a central control unit for HVAC installations («Heating, Ventilation, & Air Conditioning») with a heat pump inside.
Areas of application:

• Heating, conditioning and heat water supply for apartment houses;
• Heating, conditioning and heat water supply for industrial and business buildings;
• Ventilation recuperators with air heating by heat pump and/or central water heating;
• Air dehumidifiers for swimming pools with heating by heat pump, electrical heaters or central water heating.

Auxiliary equipment - Impulse Interference Protection Filters for 1wire temperature sensors (DS18b20) - allow temperature sensors to work in conditions of excessive interference from the BLDC compressor and it's driver.

Filters are installed on the cable between the sensor and the controller at a distance of 10-20 cm from the sensor. It's also possible to install filter directly inside the sensor enclosure.

Temperature Sensors (DS18b20) with integrated Filters provide stable operation in the conditions of impulse interference from a BLDC compressor. The only drawback compared with Chinese sensors is the increased cost. Everything else - the benefits:

• 6x50mm stainless steel sleeve;
• Copper wire double-insulated shielded signal cable;
• Original DS18b20 chips from a reliable supplier;
• Built-in impulse interference filter;
• Multi-level moisture protection, providing a level of protection "IP68" at least;
• Heat sink compound to ensure reliable thermal contact of the metal sleeve and the sensor body;
• Testing each sensor during production for 1 hour at temperatures of -15 and +100 °С.

Key features of new device:

• Increased performance and flexibility through the use of a Linux-powered single-board computer (SBC);
• Communication interfaces: Ethernet, WiFi;
• Ability to install a built-in submodule of GSM / GPRS modem;
• All discrete outputs are designed to control external electromechanical or solid-state relays;
• A block of external electromechanical relays with integrated spark circuits, carried outside the main body, provides additional flexibility and surge immunity of the system;
• RMS-meters of 3-phase power voltages (increased measurement accuracy and noise immunity);
• Flexible configuration of inputs and outputs;
• Ability to add your own custom control algorithms.
