Our controllers are able to operate in ambient air temperature up to
40C. By this I mean that the control will operate normally even if
the air temperature during the day reaches 40C. The control will also
operate happily in temperatures to minus 5c. Electronics are far better coping with cold than heat.
As part of our testing a control was fitted to a pump running at maximum for long periods the Temperature
of the Control enclosure did not exceed 52C with the internal PCB temperature being 81C.
These temperatures are far in access of what would be seen in a system. For a control to begin to melt
temperature would have to be well above 300C at this point the PCB may begin to smoke However it will
not flame. In other words this is the equivalent of placing the controller in your oven and turning
temperature to maximum.
Note: It should be said that simply fitting the correct rated fuse will avoid any possibility of current feeding a
fault condition to these extreme temperatures.
If the Control is experiencing very high temperature it will shut down the pump to protect it self and the
system.
Summing up then we have looked at the importance of correct fusing together with the risks associated
with not fitting the fuse. Also we looked at the power supply (battery) The importance of cable
maintenance and replacing worn or damaged connectors.
At Heart Spring is an electronics company following many years testing and development our controllers
have a range of self protection and safety systems built in, that many controls do not. That said the article is
aimed at both those who use a controller and those who do not.
As an electronics company development is an evolution so who knows what may come next.
Your safety and ability to earn a return on your investment relies on maintaining and inspecting your system
periodically. A few minutes regular maintenance can save you a whole load of problems later.
I hope this article has changed a few miss conceptions and got people thinking.
Be safe out there and if your not sure please ask.
