If the sensors are not accurate the billing in return is not accurate. The HCM4 uses a unique and patented system called DHAS 
(Digital High Accuracy Sensors) The accuracy is so good the high precision versions the accuracy is in the region of 0.02%. 
The DHAS system takes a temperature reading every half second.

Q6 - I ve fitted Temperature sensors in the past before and they are a nightmare if you wire them incorrectly,or
cut the length or want sensors over 10 metres long ?
A6 - Thats true standard sensors can be awkward to install. The HCM4 uses the unique DHAS sensors which are 
digital and have two way communication between the calculator module and the sensor head. This means the 
micro processors intelligence finds each sensor and knows exactly if its connected to a flow or return pipe.
The DHAS can be cut to different lengths to suit without damaging accuracy and the can transmit up to
10 metres. (standard version and 200 metres LD version) 
LD Version - This is a unique feature only available via the HCM4 system
