Working principle
ST-27i regulator is intended to control the operation of CH circulation pump and of the additional pump (HUW or floor pump). The controller's task is to switch the CH pump on if the temperature exceeds the threshold value of activation and to switch the pump off when the boiler cools down (e.g. as a result of burnout). For the second pump, apart from activation temperature, the user adjusts the set temperature up to which the pump will operate.
Controller Functionality
- CH pump control
- control of additional HUW or floor pump
- anti-stop function
- anti-freeze function
Controller Equipment
- LCD display
- CH temperature sensor
- temperature sensor of the additional pump
- knob of the pulse generator
- casing made of high quality materials resistant to high and low temperatures
