my need: Order starting a pump system for balloon derivative ECS - I took a machine to test his reflexes and operation (simplicity, comfort, precision ...) while my circuit requires 3 - having Price matches the cost of my installation, this is acceptable - I said that the optional electronic board my boiler is 300 euros + a technician! - Equipment received, well packaged, with its probe - first tests, the features are consistent with the description and meet me - the accuracy is at the rendezvous and hysteresis is observed, and the responsiveness of time (adjustable) - side ergonomics is acceptable, even if the transition logic values somewhat escapes me - side comfort .... ditto small button, not very nice to drive ... but once set, it does not return to in theory - I simulated a power failure (rather jumps) a few minutes: the recorded data safely - what about after a few hours ...? test - the display is very nice and big! which allows to see from afar - the instructions are indigent, as often with imported products - but handymen make abstraction - is the issue of product durability over time ... for now my Evaluation is 5 stars because I do not have the right to assume the intellectual disqualification of hypothetical product: I'll come back if he does not shock!
