I got given a temp controlled thermostat not so long ago, a friend thought I could use it on my cab. It is actually a 230v AC fan connected to a Pfannenberg thermostat FLZ 530.
It has an analog dial to control temperature and it works when you move the dial and the thermostat kicks in but bizarrely it seems to kick in when I turn the temperature dial down. The dial is marked as 0-60'c and seems to kick in at about 10'c.
I found a datasheet online for it
here, but not be an electronics type, the speak confuses me slightly...
It says "FLZ 530 – Shutter (Contact closes with rising temperature – Setting knob with blue imprint)"
to me this implies as temp goes up the circuit is made and live is switched so the fan receives power?
it then goes on to say...
"- For the temperature setting of the opener the highest possible hysteresis must be added to the required minimum temperature.
For example: - required minimum temperature inside switch cabinet: 9°C (46°F)
- temperature to be set: 20°C (66°F)
- resulting from: 20°C (66°F) = required temperature 9°C + highest
possible hysteresis 11K (7K+4K)"
What?
Am I actually holding a thermostat that only kicks in when temperature gets too low?
It also goes on to say, "The information on the name plate (voltage and current) is to be heeded." - obviously but the name plate says 6a, but presumably when the circuit is closed this is just max load and the fan determines the actual amps (which is 15w)?
And finally, "- The thermostat should be assembled in the upper part of the switch cabinet at the maximum possible distance from heat creating components.".
I am thinking of using this not on my cab but in a small cabinet where my xbox, dvd and sky box live which gets hot as you can imagine! Anyone think this would not be an appropriate use of the device
