NOWOSOLAR PK-23 boiler automation for 2 pumps

The NOWOSOLAR PK-23 controller controls the blower fan and two circulation pumps (the hot water supply pump and the central heating system pump). The hot water supply pump has priority. If the temperature in the hot water tank reaches a preset level, the central heating system pump is activated. It features a purge function: when the temperature exceeds a specified level, the fan periodically shuts off after a user-specified time. The operating time and pause time can be changed at any time. The controller has 8 blower force levels. The controller is available in several versions, depending on the boiler type. The program is individually designed for each customer, and the wire length is selected to ensure quick and easy installation.
