we got the same problem as you described above long time ago, what we did just to change the 启动温度 range from the default (0.1度) to 1度, it fixed the problem and we found it saved a lot of gas as well.我家的锅炉是在20度时就启动,大概运行8分钟,并还在20度时停止。而且,没有选项很简单,并没有启动温度和设定温度。
记得去年最冷的时候,锅炉与会最多大1、2小时才会工作一次,因为启动间隔很长,并没有个确切地概念。
