Network optimization information:

If only heating is required, set heating mode. When the return water temperature in the air conditioning pipeline is lower than 40 ℃, heating will be started until the return water temperature is higher than 45 ℃ (settable value); hot water will not work. With this mode, the air conditioning terminal (fan coil unit) can be started, or the floor heating thermostat can be started to obtain a warm and comfortable indoor environment with constant temperature.

If heating and hot water are needed, set "heating and hot water mode". In this mode, when the temperature of the hot water tank is lower than 50 ℃, start to run "hot water making" until the water temperature of the hot water tank reaches 55 ℃; when the return water temperature of the air-conditioning pipe or the floor heating pipe is lower than 40 ℃, start to run until the return water temperature is higher than 45 ℃ (can be set); when the "heating pipe" and "heating pipe" temperature of the hot water tank are both lower than 40 ℃, it is better Start the hot water system first, until it reaches the set temperature. Under the mode of national standard of two combined supply, the indoor environment with constant temperature and warm comfort can be obtained by turning on the air conditioner (fan coil unit) or the floor heating thermostat; the domestic hot water of 50-55 ℃ can be obtained by turning on the hot water tap.
