Description
Manufacturer: LK Armatur AB (Sweden)
To save energy, an accessory is available that monitors the operation of the circulation pump. The pump stops 30 minutes after the actuator has fully closed the mixing valve. The pump starts again as soon as the actuator opens the mixing valve. This also applies when the mixing valve is opened manually.
Installation
See the heating system diagram: pump control (image 2)
Maintenance of the pump and mixing valve
The system detects whether the pump control unit is connected and starts the pump every 48 operating hours for 1 minute with the mixing valve closed. If the pump has stopped, the mixing valve opens fully and then closes again. When the maintenance cycle is complete, the system returns to normal operation.
