NOTE: A range of advanced factory fitted and plug-in control options are available from Biddle to enhance the
performance of the CCS PCB inside the air curtain. These include advanced weather compensation
control using a heating curve, outlet air temperature control, ECObus
modulating heater outputs and EEPROMs for non-standard control strategies. Visit the Biddle website
for details.
TRANSFORMER SPEED CONTROLLER
The transformer speed controller fitted to each Style
(see below). The transformer tapping output voltages are factory set to three suitable voltages for high,
medium and low fan speeds. For 2m air curtains both transformers are connected. For 1m and 1.5m
units only one transformer is connected. If fan speed voltage adjustment is required for any of the
speeds, move the appropriate fan speed voltage cable (Black – High Speed wire, Blue – Medium Speed
wire and Red – Low Speed wire) to a different transformer voltage tapping.
The Black, Blue and Red wires for the fan speeds must be connected to the same voltage tappings on
both transformers i.e. if the Blue medium speed wire is connected to 100V tapping on one transformer
it must be connected to the 100V tapping on the other transformer.
