How to use wall-hung boiler to save natural gas?

The temperature controller connects the indoor greenhouse with the wall-hung boiler through the signal line, and can set the temperature in different time periods. My family can set 6 time periods in a day, and 6 time periods can set different temperatures. When the temperature can't reach the set temperature within a fixed period of time, the wall-hung boiler will start automatically, and when the temperature reaches the set temperature, the wall-hung boiler will shut down automatically, which saves gas and is much more convenient!
