propex power switch?

[itchyfeet]

Is one needed?
fan spins up when you connect power
measures no current draw when off (Thermostat switch middle position) with my multimeter so is there any need to switch it off? Not sure if it takes power periodically
anybody else switch it seperately?

I've wondered the same thing, but mostly because the switch on the control unit feels too easy to accidentally knock to one side or the other. And I've also not yet had a chance to check the current draw if the unit is switched on (left position) but stays off because the temperature is above the thermostat setting. I imagine any current draw would be minimal, since it would only be monitoring the ambient temperature.

Interested to read other replies.

Well I can think of one reason. I wired mine to a 7 day week timer so that during the winter months it will come on 3/4 of an hour before I drive to work. If for whatever reason I don't want it on the next day, I only have to switch propex to off and then it doesn't matter what the timer does. I could mess with the timer but its far simpler to hit the off switch.

One of these in fact: http://www.ebay.co.uk/itm/New-LCD-Digit ... 19ea7afe54" onclick="window.open(this.href);return false;

My Propex is an X1 (early model). It doesn't have a thermostat, just an on/off switch beside the zig unit. I can't see any problem with fitting an additional switch to a thermostat version.

neither can i but the question is do i need one?
will i get battery drain without one?

liking the timer covkid

You'll only get battery drain if the switch gets accidently toggled to an on position. Or if the kids get to it

No kids, its a 2 seater

That makes it two big kids, 'cus you have to have a bit of the kid in you to love these beauties.

[itchyfeet]

Yeh im a big kid you are right

if i did have kids id have to admit im an adult and thats not going to happen

The draw of my Propex when in use is 2.3 amps, and that is when there is ignition and the fan spinning. I think it's a good idea that the thermostat has an on/off switch even though you could leave the unit turned on and just set the thermostat to the lowest position. Just don't get to that temp and you'll be all set but for me the on/off is just fine.

No master switch on mine, no problems, no current draw when idle

Correct me if I am wrong but when the stat cuts out the fan runs for a time to cool the Inerds if you fit a switch and switch it off when hot the internals will cook.

correct it is not good to switch it off before it's purged but my guess is that it is designed to fail safe, after all what happens if the fuse blows or the battery low voltage relay trips out when in use.

That's when the heat exchanger can get distorted with the uneven cooling same as Eberspächers and Webastos - I wouldn't shut a heater off without the cool down running period.

Ok so a low battery shut off relay is not good
I suppose you could use the low voltage relay to sound a buzzer
