enter it during the manufacture or installation of
the unit.
Ventilation connections
From the factory, the VenTum is configured to
connect the return air duct on the left side of the
unit. If the desired return is below or on the left
side of the unit, simply remove the panel covering
the desired opening of the unit and reinstall it on
the right side to close this opening.
Do not forget
to unhook and remove the section of
insulation covering the chosen opening.
The
unit’s possible installation configurations are
shown in Figures 4 and 5. An installation that is
not shown in one of the possible configurations
will void the warranty in the event of a defect.
A filter holder is supplied with the unit to make it
easier to connect the return air duct and insert a
filter.
A MERV category 5 or less filter must be installed
at the return air opening using the supplied filter
holder or a field fabricated filter holder depending
on the required filter dimensions. Thermo 2000
suggests replacing this filter every 3 months or as
recommended by the manufacturer of the
installed filter.

All ventilation ducts must be designed in
accordance with good practice and applicable
ventilation codes to reduce the risk of ventilation
noise and excessively high pressures. The AHRI
"J" and "D" manuals are indicated for the design
of ventilation ducts.
The plenums must be manufactured on site to the
dimensions of the
VenTum unit’s connection
flanges (see figures 1 and 2). The air outlet
plenum should ideally consist of a straight section
of at least 1 meter (3 feet) before adding
branches or curves.
It is recommended that the ventilation ducts be
insulated with 1 inch (1”) fiberglass insulation and
vapor barrier to reduce the risk of noise and
excessive condensation on the duct surfaces. It
is generally recommended not to exceed an air
speed of 3 m/s (600 ft/min) in the ventilation ducts
to reduce the risk of noise.
The total external static pressure must not
exceed 0.75 in water column.
Air-conditioning coil
An air-conditioning coil can be paired with the
VenTum unit. Compatibility is possible with a heat
pump or air conditioner type outdoor unit only.
The air conditioning coil (not supplied by Thermo
2000) must be installed in accordance with the
standards in force as well as the manufacturer's
recommendations. A drainage pan MUST be
installed with an air-conditioning coil so that the
condensation drains into a drain provided for this
purpose. Condensation from the air-conditioning
coil must not drip into or onto the VenTum fan coil.
An installation without a drain pan will void the
warranty.
The air-conditioning coil can be installed
upstream or downstream of the fan coil. In order
to reduce any risk of the hot water heating
radiator freezing, Thermo 2000 recommends
installing
the said air-conditioning coil
downstream (at the air outlet) of the VenTum
hydronic air-handler. If a heat pump is installed
for heating purposes, the heating efficiency will
be higher with the coil upstream of the hydronic
air-handler.
It is important to position the air outlet
temperature sensor as described in the following
Section (3.5.4.)
Temperature sensors
The VenTum hydronic air-handler has three (3)
temperature sensors, two (2) of which must be
positioned during installation. The sensor marked
"Sortie Air / Air output" must be installed at least
30 cm (12 in) after the heating coil or,
downstream of the air-conditioning coil (if such a
coil is installed above the heating coil) (see
position 14 on figure 6). If an air-conditioning coil
is installed upstream of the heating coil, install the
sensor as indicated after the heating coil. In the
event where the cooling coil is located in the
return air duct, the sensor marked
“Entrée Air / Air
Input
” must be relocated before the cooling coil
(see postion 22 on figure 6).
The reading of the air outlet temperature is used
for the correct operation of the unit and to
prevent:
•
Freezing of the heating coil.
•
Freezing of the air-conditioning coil,
