■ Quietside offers new and improved ways of
getting the best comfort from your new unit.
The FR-5 thermostat is an advanced, multi-
function room thermostat that features a direct-
readout L.E.D. panel giving you accurate
temperature control of your environment as well
as displaying information about the performance
and condition of your hydronic heating system.
■ There are two ways of sensing temperature for the
purpose of heating your home ; the most common
is simply by sensing the air temperature within the
main living area, typically where you spend the most
time. The other is by sensing the exact temperature
of the heating water delivered by the unit.
■ With the FR-5 thermostat, both of these methods are
available to you. Now you can choose the simplicity
of setting your temperature by air(maintaining room
temperature) or the convenience and comfort of
setting your temperature by water(maintaining a
constant heating-water temperature).
■ The temperature of the air within the living space
of the home can vary from five to ten degrees. It
is difficult to sense the exact temperatures of all
areas within the home when the thermostat is
located in just one room.
■ Well-insulated homes of average design and
families with active lifestyles should find that
setting the thermostat to the air temperature-
sensing function will provide the best comfort.
■ Other homes with unusually high ceilings,
inadequate insulation, leaky windows, long drafty
hallways or simply have people who tend to feel
drafts and chills more than others could find that
setting the thermostat to the water temperature-
sensing function will provide the best comfort. We
suggest trying them both.
[The Air Temperature Mode]
The QVM 9 hydronic
heating system has built-
in artificial intelligence. In
the air sensing mode, the
FR-5 thermostat is busy
tracking the room set-
temperature.
By incorporating the use
of a pre-programmed microchip, the QVM 9 hydronic
heating system accurately adjusts the modulating combustion
process to best suit the changing needs of the home.
[The Water Temperature Mode]
In the water-sensing mode,
the FR-5 thermostat works
with the unit to maintain a
constant water temperature
condition. There is no sensing
of room temperature in the
water temperature sensing mode
of operating and therefore,
small adjustments and fine
-tuning will need to be made from time to time.
[Energy Saving Mode]
In winter, if you’re leaving
for work or plan to be away
for several hours or several
days, you can select the
‘unoccupied(Away from Home
Saving)’ mode to reduce
energy costs. During these
periods when the home is
vacant, you can program the
thermostat to operate the
unit in a ‘stand-by’ mode where the unit will cease to
operate in the normal heating function. In stand-by, the
thermostat tells the unit to only operate for very brief
intervals; for the period you have selected(anywhere from
0 to 4 hours). When you return. Select the preferred
temperature and press the heating mode button.
On the following pages you will find the FR-5
operating instructions describing how to operate this
device add convenience to your life while keeping
you and your home more comfortable.
