发帖数: 268 | 1 室外温度50度左右，室内温度60度，当时HEAT PUMP是开着的指在HEAT上，我将它调到
66度，马上启动，而且AUX的灯一直亮着。到了66度后，将其调到68度，AUX的灯就不亮
了。这正常吗？
谢谢赐教！ | C*******d
发帖数: 15836 | 2 I see no problem. When you first change T from 60 to 66, the jump is so high
so that aux heat is started to get there faster. When you change from 66 to
68, the jump is small, so no aux is needed to get there in a reasonable
amount of time. |
