Our most popular circuit board: This PCB is designed to fit in Daikin air-con / heat-pumps to provide WiFi control and integration. Unlike the standard Daikin WiFi this is stand alone and does not need Internet access or an account on a cloud system. It fits the standard "S21" connector - some Daikin units have a lead for this as standard and others need a lead, which can often be purchased from Daikin or other suppliers, or home made.
