ACCESSORIES
Vertical
Louvres
Vertical louvres may be added as an option and are recommended
where low discharge air temperatures are used.
Horizontal louvres are fitted as standard on TA and STA units and may be ordered as an option on TB, STB, TE and STE units.
Downturn Nozzles
Optional 30o
or 60o
downturn nozzles increase the angle of air discharge and are
recommended for units installed above the minimum mounting height.
Axial fan models may be fitted with either 30o
or 60o
nozzles, but vertical louvres can only be added to 30o
nozzles.
Centrifugal blower models may have 30o, 60o or 90o nozzles fitted and vertical louvres may be added as required to any nozzle.
For heaters at extreme mounting height a 90o head complete with discharge plenum may be fitted. The air may be directed using a two way or four outlet to give the air distribution pattern required.

Destratification
Fans
Destratification fans return air from the roof space back down to
the working zone. They may also be successfully applied in modern well
insulated buildings where low heat inputs require additional air
recirculation to ensure even temperature distribution.
Depending on the application, the
destratification fans should be selected to provide between 1.5 to 4
volume turnovers per hour. Two models are available:
. DS
5 - 4,900m3/hr
for mounting heights between 5 and 10 metres;
. DS 10 - 10,250m3/hr
for mounting heights between 10 and 15 metres;
Control
Panels
Ambi Stat remote control panels provide:
. Digital
time control
. Day
and night temperature thermostats
. Summer
'fan only' facility
. Remote
'lockout reset' for units fitted with auto ignition
Ambi
Tec II panels are fully electronic controllers and have a remote
tamperproof sensor for greater accuracy and energy saving. A single
sensor provides both day and night temperature settings, the sensor
may be sited up to 100 metres from the panel. The units feature:
. Digital
time control
. Single
sensor for day and night settings
. Timed
summer 'fan only' operation
. Remote
'lockout reset' for units fitted with auto ignition
Ambi Tec EM I panels are micro
processor Energy Management controllers and share the same basic features
as the Ambi Tec II plus an optimum start facility. The Ambi Tec EM I
units must be specified for units with two stage High Low burner
control, fully modulating burner control or constant fan operation.
