水草情迷

我20吋缸, 請問點解我支Tetra暖管set溫度去到20C (最低), 水溫就去到28C呢? 係唔係恒溫制壞左?

暖管 could not lower the water temp..........

If you set 20C, then it not work lor (keep standby until the temp lower than 20C)....

謝謝回覆, 唔好意思, 問題欠長盡, 早兩天氣溫轉涼, 晚上關燈久後, 未開暖管水溫22C, 於是乎開暖管(set 20 C, 唔係想用暖管整凍d水, 真幽默 ), 但水溫數小時後達到28C先停.

...so funny?! If you set 20C, it will not take effect if "水溫22C" wor......you sure your 暖管 is working at that time?

Thanks again! Please, I am just trying to prove my tube is working according to the temperature as set, you are right, it is supposed STOP HEATING if the temperature is higher than 20C, BUT IT DID WORK KEEP HEATING MY TANK up to 28C I am sure it is broken but just wanted to share if someone who encountered the same question. How about you? kpchg4? Your tank's temperature is maintained as the temperature you set to your heating tube? Can you let me know what brand is it, if so?
