Page 19: General Applications
3.3 General Applications ： 3.3.1 Heating only function This application is recommended for using heating (floor/radiator/fan coil) only purposes. - Page 20 Remark: 1. The water divider and water collector are used for water distribution when multiple end-use heating equipments are installed at the same time. 2. After connected to the linkage signal line, each individual thermostat can control the oper- ation or shutdown of the heat pump. If didn't connect to the linkage signal line, the heat pump will operate until the shutdown conditions of the heat pump are met (whether the end-use heating is using or not).
- Page 21 3.3 General Applications ： 3.3.2 Heating + hot water function This application is recommended for using heating (floor/radiator/fan coil) and DHW purposes with a low cost of installation.
