Default Humidity problem

(Joe Sallustio) wrote in message . com...
Seb,
Is it running all the time when you are set to 18 C? If so, that is
the limit of the unit, you would need a bigger one. 8000 BTU's should
get that room pretty cold.

You can buy lower temperature thermostats if it's not always on, or
maybe you can play with the calibration of the thermostat. That voids
the warranty, so I'm not suggesting you do that on a brand new unit.
If you were to try that, you would pull the knob off of the one you
have and see if the shaft is hollow. If so, it may have a calibration
screw inside you can adjust. Often times there is a set screw on top
of the adjusting screw to lock it down that has to be removed; I would
think GE would do that, it's a good unit. Some of them have an
adjustable stop that sits on the outer ring of the mounting stub
instead.

All it really is is a switch, if you bought a lower temp thermostat
you would just replace it. If you do decide to play with that
remember to mark your starting point so you can undo the adjustment...

The cheapest line voltage thermostat I see in Johnstone supply that
works for cooling is a ETD5SS for around $14 (US). (You want the SPDT
action, you want it to go off on temperature 'fall'.) It does not say
who makes it, sorry. It says it goes from 50 F to 90F. The Johnstone
PN is L37-725. Grainer is in Canada, they would sell these too. Or,
just look up appliance repair in your phone book for suppliers.

If your relative humidity is still at 80% with it running you may have
a water problem in the walls or floor. The cooling coils in the AC
will still be well below 18 C and moisture should be condensing on
them and draining out. If that drips into a bucket and is a few
gallons per day it's coming in the basement somewhere. It could take
several days to dehumidify, give it at least a week before doing
anything.

Hope that helps,
Joe

Thanks a lot Joe, in fact the unit is brand new, didn't install them
yet. I just read in the manual that the setting are between 18 C and
30 C. Since my room is normally at 17-18 C I guess the unit will not
turn on ? So, that's why i whant to play with some mod on the unit.
The control panel is electronic, no varistor to adjust. But, i am
thinking of placing the thermostat higher and also isolating it so the
unit should work cooler like 16 C maybe ? I will try that and if it
didn't work i will replace the thermostat with the unit you give to
me. I don't really mather with the warranty, I will just let them
work without any mod for one or two weeks to be sure he is working ok
and then i will begin to play with it. This 8000 BTu should be more
than enough for a 16 X 16 room.

Thanks,
Séb
