OVATION 214
ZONED OR CASCADING HEATERS
FULL-SPEED FAN START-UP
In order to overcome the inertia of the ventilation system components and
de-ice the fan blades in cold weather conditions, the controller supplies
maximum voltage to the variable speed fans during the 2 seconds imme-
diately following each start-up.
DE-ICING CYCLE
A de-icing cycle is provided for de-icing stage 2 variable-speed fans in
cold weather conditions.
FOUR INDEPENDENT TEMPERATURE PROBE INPUTS
Up to four temperature probes can be connected to the controller in order
to obtain a more accurate reading of the average room temperature and a
faster reaction time.
OUTSIDE TEMPERATURE COMPENSATION ON CURTAIN SPEED
Curtain opening and closing times can be decreased as a function of out-
side temperature.
OVERLOAD AND OVERVOLTAGE PROTECTION
Fuses are installed at the input and outputs of the controller to protect its
circuitry in the case of an overload or overvoltage.
MEMORY CARD:
A memory card is used to create a copy of your controller's parameters.
COMPUTER CONTROL
The controller can be connected to a computer, thus making it possible to
centralize the management of information and diversify control strategies.
CONTROL OF AIR INLET MOVEMENT
If the OVATION 214 is used in combination with a DWR-F-1A controller,
the movement of the air inlets can be coordinated with the operation of
the fans using a potentiometer located on the panel drive. This allows the
air inlets to be adjusted correctly, without the influence of uncontrollable
factors such as wind or air from adjoining rooms.
TEST MODE
A test mode allows you to simulate temperature changes and verify con-
troller performance.
