June 10, 2005 - Friday - This picture shows the laundry room with the two
Seisco on-demand water heaters mounted on
the walls. The white unit on the left is the model RA-28 which will
supply all the domestic hot water needs for the home. The grey unit on the
left is the model SH-14 which will provide hot water for the radiant floor
heating system. This picture also shows a great shot of the completely
wired breaker panel. Notice that both of the water heaters and the
Ipex Zone Control Panel all have grey
metal, flexible conduit connecting them to the breaker panel. This is
because wires can not be exposed in an area where humans could touch them. Also notice each water heater has TWO
conduits. This is because each water heater requires two 240 volt circuits,
with each one run in its own conduit. As a last note, the red and white
PEX tubes that look like they are connected to the white Seisco unit are
actually for the clothes washing machine and are just resting against the Seisco
heater, not connected to it.
June 10, 2005 - Friday - As part of last week's pictures we detailed at great
length the multi-port ventilators we are using; one for bathroom exhausts and
one for a whole house fan. Controlling one of these multi-port ventilators
servicing the three humid areas in the home (each bathroom and the laundry room)
is a bit of a challenge however. Most bathroom fans are controlled either
by a rotary timer the occupant manually sets when using the room, or by simply
making the fan come on whenever the light is turned on. We like to have our
exhaust fans on for a good while after the user has left the room so just
having the fan controlled by the light switch is not an acceptable option for
us. Unfortunately no one seems to make rotary timer switches that can
support a four-way wiring schematic (if you have three switches controlling the
same fixture it is called a four-way switch...go figure). After a long
search and many phone calls we talked to the good guys in the tech support dept.
of Leviton. The great guy we spoke
to didn't skip a beat when we described what we needed. "You need an
OSD10-IDW. Its a miracle switch". He then went on to detail
that it can handle 120 or 240 volts and that it can be installed in a 4-way
switching scheme. When asked how many of these little wonders could a
person have
controlling one load he said "pretty much as many as you want". These switches are called "occupancy sensors". In actually
they are infrared motion detectors. In addition to their many great
features they have a user programmable "delayed off setting". This means
they fit our requirements to a "T". This delayed off feature means we can
program the switch to stay on for 30 seconds to 30 minutes after it no
longer senses any motion! Perfect! To put icing on the cake, they
are the exact same size as our "Decora" style light switches! Cool!
To make a long story shorter, we have had one of these units installed in the master
bathroom, the guest bathroom, and the laundry room. With this arrangement
the fan will stay on as long as we like (up to 30 minutes) after any of
these three switches stops detecting motion! Just like on the Starship
Enterprise! This picture shows the
OSD10-IDW in the laundry room mounted next to the light switch. Last
comment is... for those of us who have cats...if you put the litter box in one
of the bathrooms or the laundry room, the cats will trigger the fan when they go
in to use the litter box! How cool is that!?!?
June 10, 2005 - Friday - Here is a picture of one of the multi-port ventilators
mounted in the attic. Its a bit hard to see, but its the black box in the
center of the picture.
June 10, 2005 - Friday - Here's a picture of one of the smoke detectors dangling
from its wires such that it is fully functional for the electrical inspector,
but can still be easily removed prior to sheet rocking.
