请教懂行的诸位
ddjj, imore etc
ac 是410a & hydronic system的。冬天冷的时候开暖气，设置到76，温度到80了还不
停。
现在夏天设置到74，结果70也不停
每次都是只好手动关机
问题是我已经连着换了三个thermostat, 还是同样的问题，现在有些束手无策了,
难道indoor coil上也有温度的sensor？可是我好像在indoor evaporator coil上好像
没看见什么，heating coil上倒是有一个sensor.

A few possible causes of Non-stop operation in your system
1) Circulator Relay on the controller: The relay is stuck or the relay
coil damage, you may use a jumper at the C1 and the C2 ( or T1 and T2 depend
on different controllers) of the aquastat controller, the circulator relay
should be closed after receiving 24v signal from the C1 and the C2. If not,
should replace the controller.
2) Sensing Bulb in bad contact with the immersion well, or sensing bulb
becomes bad. The sensing bulb should be placed in the right position in the
immersion well, and therefore it can sense the right temperature from the
boiler. Or could be capillary tube bend damage as well, you should find a
good professional for replacement.
You also need to know, the high limit setting can't over 200F for a safety
issue.
