Intelligent solid fuel boiler control with Unister damper

The Unister electronic draft regulator is a reliable solution for precise temperature control in solid fuel boilers. The device automatically adjusts the air supply to the combustion chamber, ensuring optimal combustion and efficient heating. Additionally, it controls the circulation pump, protecting the installation from overheating and freezing. The Unister damper is a combination of functionality, reliability and intuitive operation, ideal for both professional installers and end users.

Functions and benefits for comfort and safety

The Unister damper offers a wide range of functions that translate into real benefits:

• Automatic draft regulation: Precise control of the air supply ensures a stable temperature in the boiler and optimal fuel combustion.
• Circulation pump control: Provides efficient heat circulation in the central heating installation, and the COMFORT SYSTEM function protects the pump from damage caused by scale build-up.
• Blow-out function: Maintains embers in the combustion chamber, which extends the burning time and reduces the need for frequent refueling.
• Failure protection: Automatic shutdown of control after the boiler has extinguished and lowering the damper in the event of a power failure increases safety.
• Air inlet closing: Allows safe refueling of the boiler without the risk of smoking the room.
• Failure signaling: Informs about a damaged temperature sensor or motor blockage, facilitating quick diagnosis and repair.
• Adjustable display brightness: Ensures readability of information in all lighting conditions.
• Expandability: Compatible with the CONTROL remote control panel, allowing convenient temperature management from anywhere in the house.

Construction and application

The Unister damper is designed for mounting on solid fuel boilers equipped with a damper regulating the air supply. The simple construction and intuitive interface make installation and operation of the device extremely easy. The regulator is made of high-quality materials, which guarantees its durability and reliability even in difficult working conditions. The device is protected against moisture (IP40) and has a class II insulation, which ensures safe use.

The measured temperature range reaches from -9 °C to +99 °C, and the boiler temperature setting range is from +40 °C to +85 °C. The damper lifting hysteresis is in the range of 0 °C to 9 °C, and the central heating pump temperature setting range is from +35 °C to +70 °C with a central heating pump hysteresis of 2 °C. The blow-out regulation allows setting the working time from 0 to 90 seconds and the break from 1 to 15 minutes. The device is powered by 230 V, 50 Hz, and the pump output capacity is 100 VA / 230 V.

The Unister damper is an investment in the comfort, savings and safety of your heating system. Thanks to precise temperature control and advanced protection functions, you can enjoy warmth in your home throughout the heating season without worrying about failures or unnecessary energy losses.
