Tech Sterowniki Sinum EH-01 controlador central preto

The Tech Sterowniki Sinum EH-01 Central Controller is a microprocessor-based control unit designed for managing heating systems with two heating pumps (CO and DHW) and one mixing valve. It features a graphic LCD display, wall-mounted plastic housing in black, and supports automatic and manual operating modes with summer/winter settings. Safety functions include anti-stop, anti-freeze, and alarm. The controller has 3 sensor inputs (CO, DHW, mixing valve return) plus one optional external input, and 3 controlled outputs (2 pumps, 1 mixing valve actuator) plus one voltage-free auxiliary output. Power supply is 230V AC, 50Hz, with max output load of 0.5A per output. Temperature measurement range is 0-90°C, operating temperature 5-50°C. Hysteresis adjustment and DHW pump priority are supported, and mixing valve control uses a proportional-integral (PI) algorithm.

Advantages

Reliable microprocessor control ensures precise temperature management. The graphic LCD provides clear status information. Safety features protect the system from freezing and stagnation. DHW priority guarantees hot water availability. The PI algorithm optimizes mixing valve operation for energy efficiency.

Suitable for

• Heating systems with two pumps (central heating and domestic hot water) and a mixing valve
• Residential and commercial buildings requiring automated temperature control
