Definition: "OPTION" are factory fitted items supplied installed
on the unit itself and ready for use; "ACCESSORY" are items
that must be installed, fully or in part, at the job site.
13.1.- Modulating economiser, temperature
controlled
Comprised of a damper located at the return end of the unit,
and another at the outdoor air intake.
This control compares the outdoor and return air values
and adjusts the opening of both dampers proportionally by
means of the 0-10v modulating actuator equipped with a
return spring.
To ensure a good level of comfort, the impulse temperature
is limited to 12° C.
The dampers are factory set for a minimum outdoor air vol-
ume of approximately 10%.
The outdoor air damper is equipped with a rain hood as-
sembly, which includes an aluminium mesh, to avoid drops
of water seeping into the unit.
This rain hood is supplied fully installed on the unit, thus
avoiding additional work at the job site. See Fig 9.
The unit is supplied with the return air damper installed at
the bottom or side, in accordance with the needs of the duct
connection (must be indicated upon placing the order, see
Fig. 10).
If necessary, the economiser can include, as options, the
enthalpy probe control (see 1-2) as well as an excess air
extraction system when required by the installation design
(see 1- and 1-4).
The economiser can be adapted to operate as a motor-driven
outdoor air damper, which makes it possible to adjust the
minimum and maximum outdoor air volume values, depend-
ing upon installation requirements; always in accordance with
the operating limits of the unit.
