Notes:
1. The thermistor can be used to detect temperature of water. If domestic hot water tank is installed only, the thermistor
can work as T5. If double zone function is used only, the thermistor can woke as Tw2. If both unit are installed, an
additional thermistor is needed (please contact the supplier).
2. When the units are connected in parallel, such as when the communication between the units is unstable (such as an Hd
fault code), add a network matching wire between the ports H1 and H2 at the terminal of the communication system.
