2 x pumps Controller EU27i

Principle of operation EU-27i regulator is intended for controlling the CH pump and an additional pump ( DHW pump or floor pump) Its 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). As regards the second pump, apart from setting the activation temperature, the user also adjusts the set temperature up to which the pump will operate.
Functions performed by the controller:
- CH pump control
- Control of additional pumps (DHW pump or floor pump)
- possible operation as a thermostat
- anti-stop function
- anti-freeze function
Equipment of controller:
- LED display
- CH temperature sensor
- Additional pump sensor
