Features

The EXPERT 2V2SA is an electronic device
used for environmental control in livestock
buildings. It allows the user to maintain a
specified target temperature by controlling
the operation of ventilation and heating
equipment. The EXPERT 2V2SA can control
the following outputs:
- 2 variable fan outputs
- on/off outputs (heaters, misters or fans)
- 1 air inlet output
- 1 0-10V output (heaters, heat mats, chim-
ney or fans)
Main Features :
LCD Display — An LCD display provides an
efficient interface for displaying, monitoring
and adjusting parameter values.
Pilot Lights — Pilot lights indicating the state
of outputs allow the user to monitor the
operation of the system without having to
enter the building.
Removable Connectors — Input connectors
can be removed from the main board to
simplify wiring.
Minimum Ventilation Cycle — When ven-
tilation is not required for reducing room
temperature, the first and second fan stages
can be operated either continuously or inter-
mittently to reduce the level of humidity and
supply oxygen to the room.
Temperature & Min. Ventilation Curves —
The controller can be set to automatically
change the temperature set point and the
minimum ventilation cycle over a given pe-
riod of time, in accordance with the user's
requirements, by specifying a temperature
curve and a minimum ventilation cycle curve
with up to ten different points each.
Choice of Ten Motor Types — The variation
in motor speed resulting from a change in
voltage will depend on the make and capac-
ity of the motor. In order to achieve a high
degree of compatibility between controller
and motor, the user can choose from among
ten different motor types, thus ensuring that
the correct voltage is supplied.
Zoned Heaters
Probe Readings Recorded For Past Days —
Minimum and maximum readings from tem-
perature probes, static pressure sensors and
humidity sensor are recorded for the current
day and the previous six days.
Water Monitoring — A pulse input is provided
for monitoring water consumption for the cur-
rent days and the previous six days.
Heater Run Time Monitoring — Heater run
times are kept in memory for the current day
and for the previous six days.
Alarm Management — Alarms are provided
for high-low temperatures, defective probes
and other system functions.
Four 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 — Fan
stages are automatically adjusted according
to the outside temperature. This ensures a
better stability in the room temperature.
0-10V Output — One 0-10V output can be
activated to control supplementary ventila-
tion or heating stages or to control chimney
dampers.
