About the FR-5 Thermostat

■

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 controller 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]

[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.

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.
