The AmbiTec Plus has been designed to
consolidate the function of all previous
control panels into one unit. All relay
outputs have volt free contracts and by
installing various links within the control
panel virtually all present, past and future
heating units can be controlled by the
AmbiTec Plus control panel. When
replacing older control panels with the
AmbiTec Plus it will be necessary to advise
the Ambi-Rad Technical Department of the
wiring diagram number of the heater in
order to develop an interconnecting
diagram.
The AmbiTec Plus may be used as a
stand-alone panel to control an individual
heater or several panels may be connected
together for multiple heater control using a
two-wire communications link.
Each AmbiTec Plus panel contains a digital
display for monitoring system operation and
a means of setting the various system
parameters by way of panel mounted push
buttons. LED indicators are used to show
Frost Protection and Burner Lockout.
The AmbiTec Plus can be used to control
ON/OFF, two stage and with a GM44
interface board, modulating burners can be
controlled.
The vent output of the unit can be used to
control ON/OFF damper motors or with
positioners mounted on the damper motor
any percentage of fresh air may be set.
Three levels of password protection are
available on the panel for the security of
settings.
