It provides centralized regulation of system temperature, enabling staged pump operation and mixing valve adjustment to maintain setpoints. Suitable for residential and small commercial heating setups requiring coordinated pump and valve control.

## Long description

Euroster UNI 4 is a temperature regulator designed for heating systems that controls two pumps and a mixing valve. It provides centralized regulation of system temperature, enabling staged pump operation and proportional mixing valve adjustment to hold setpoints. The controller is intended for residential and small commercial heating installations where coordinated management of heat distribution and return temperatures is required.
Advantages
UNI 4 combines pump sequencing and mixing valve control in one compact unit, reducing the need for separate controllers. The regulator supports staged operation of two circulation pumps and a mixing actuator to maintain target flow or return temperatures. Built for straightforward integration, it simplifies wiring and system logic for installers and allows practical adjustment of temperature setpoints and delays for reliable operation.
Suitable for
Central heating systems in single-family homes
Small apartment buildings or light commercial premises
Systems requiring coordinated control of circulation pumps and a mixing valve
Retrofit projects where space for additional control modules is limited
Key specifications
Control targets: two circulation pumps and one mixing valve actuator
Temperature regulation: centralized setpoint control with staged pump activation
Mixing valve control: proportional adjustment to maintain set temperature
Inputs/outputs: electrical control outputs for pumps and valve actuator (voltage/current type depends on installation)
Installation type: wall- or panel-mounted controller for heating system cabinets
User interface: adjustment dials or buttons for setpoint and timing configuration
How to use
Install the Euroster UNI 4 in the heating system control cabinet or on a suitable wall surface following local electrical regulations. Connect temperature sensors, pump power outputs and the mixing valve actuator according to the wiring diagram provided by the manufacturer. Configure the desired temperature setpoint and define pump staging thresholds and delays using the controller’s settings. After commissioning, monitor system temperature and adjust setpoints or delay parameters as needed to achieve stable operation.
Usage recommendations
For reliable performance, use compatible temperature sensors and actuators specified by the system designer or installer. Verify electrical ratings of pumps and valve actuators before connection and protect circuits with appropriate fuses or breakers. Schedule regular inspections to ensure sensors and actuators remain functional and recalibrate setpoints when changes to the heating system are made.
