Digital Controllers

[Abe]

Anywhere you go these days, you come across cabinets controlled by those small , neat controllers with their red led's flashing temps, and sometimes bleeping their dreaded alarms.

These are usually programmed and probably dont ever need to be reset again

But what if you have to? and youre faced with an unfamiliar make

Eliwell, Lae, Carell.........are the recognisable makes
I keep a set of programming parameters for each one in my van

What do you do? Is there a magic formula dealing with these things?

Or am I becoming paranoid for nothing?

yes, there is a formula.... If it doesn't work, if you don't know how to work it, or even if you don't like the look of it, slap on a mechanical t'stat and come back with something familiar (Lae,Eliwell,Carel). Tell the customer its dead, its cheap-thats why its dead and sell them a better one.
