Description
The Gledhill PulsaCoil 3 pump speed control board works along side the DHW sensor and store sensor. The DHW sensor and store sensor informs the PulsaCoil pump speed control board the temperature that is present and available.
The pump speed control board then sends the required voltage to the pump. The more voltage it sends the faster the pump spins and circulate hot water through the plate heat exchanger. Please only attach a Grundfos modulating pump to this board.
