Product information

Description

DK System electronic draught regulator UNISTER 201303 is a control device designed for use with solid fuel boilers. It manages the air inlet flap and the central heating pump to stabilise combustion and distribute heat more evenly. The regulator receives input from boiler sensors and adjusts actuator outputs to maintain target temperatures and safer operation in residential or small commercial heating setups.

Advantages

The regulator provides automated control of combustion air and pump operation, reducing the need for manual adjustments and helping to maintain steady boiler temperature. It integrates with existing boiler sensors and actuators to modulate airflow and pump cycling, which can improve fuel efficiency and reduce temperature fluctuations. The device is applicable to a range of solid fuel installations and is intended to enhance operational safety by preventing overheating and poor combustion conditions.

Suitable for

  • Residential solid fuel boilers requiring automated draught and pump control
  • Small commercial heating systems with a single heating circuit
  • Retrofitting older boilers to add electronic control of air inlet and pump
  • Installations seeking improved temperature stability and safer combustion

Key specifications

  • Function: automatic control of air inlet flap (draught regulation) and central heating pump
  • Inputs: interfaces with boiler temperature sensors for feedback control
  • Outputs: actuator control for air flap and relay control for heating pump
  • Application: designed for solid fuel boilers in residential and small commercial environments
  • Operating objective: maintain optimal combustion and heat distribution

How to use

Mount the regulator in a location close to the boiler control connections and follow the manufacturer’s wiring diagram to connect temperature sensors, air flap actuator and central heating pump. Configure setpoints and control parameters according to the boiler type and heating system characteristics so sensor feedback can be translated into appropriate air flap and pump actions. Verify correct actuator movement and pump switching during an initial test run and monitor boiler temperature to ensure the regulator maintains stable operation.

Usage recommendations

Ensure sensors are installed in representative locations on the boiler to provide accurate temperature readings, and use appropriate actuator and pump interfaces compatible with the regulator. Perform periodic checks of electrical connections and mechanical linkages to the air inlet flap, and follow local safety rules for fuel-burning appliances when adjusting control parameters.
