Hi...hitectrons,I Take 2 Unit HT310 Heat, Shipping FEE charge RM6.00 can?
hitectrons reply: (2012/11/2 14:11)  
Yes, we can just charge you RM6 for 2 pcs.
TQ for your support.
jhs9652 ask: (2012/10/22 12:10)  
which one can produce sound or any signal if the temperature is higher than the level that i set
hitectrons reply: (2012/10/22 15:12)  
HT635 and HT672 can provide sound ( if you connect a buzzer to the relay's output)

HT672 has LCD display but HT635 doesn't have any display.
jhs9652 ask: (2012/10/19 21:41)  
hi, can i set the temperature level that can detect by this heat detector?
hitectrons reply: (2012/10/20 10:11)  
you can set temperature level, but not the specific temperature. i.e: you do not know how many degree of temperature was setting.

We suggest you use HT672 or HT635 if you want to set specifioc temperature.
Thank you
