CONTROLLER TEMPERATURE CONTROLLER FOR CHARGING BOILER ST-28N TECH

✅The ST-28N regulator is designed for central heating boilers.

✅It controls the central heating water circulation pump, the DHW hot water pump and the blowing (fan). If the boiler temperature is below the set temperature, the controller is in a duty cycle in which the blower is running at all times.

✅If the boiler temperature is equal to or higher than the set temperature, then the controller is in a hold cycle,

And the controller works by turning on the blow-bys at a frequency depending on the user's settings.

✅The operating time and blow-by intervals in maintenance should be selected according to the type of fuel burned in the boiler.

✅control of the operation of the fan, central heating pump, hot water pump,

✅ possibility of connecting a room controller with traditional communication (two-state – on/off),

✅ automatic adjustment of fan speed when approaching the set temperature.

✅Prevents CO from breaking through the set temperature.

✅central heating temperature sensor,

✅DHW temperature sensor

✅ Lcd

✅ thermal protection.
