Valent 487416 IVE Microprocessor Controller

Готовоview

The Microprocessor Controller for Energy Recovery Ventilators provides monitoring and adjustment of unit parameters via a lighted graphical display and integral pushbutton keypad. It supports pre-programmed, user-adjustable control sequences for ventilation, energy recovery, and tempered air, with optional remote access and BMS communications.

Спецификације

Брзи почетак

1. Review pre-programmed sequences: factory default settings provide an initial setup; sequence parameters are user adjustable.
2. Enable or disable the unit using the controller: open Унит Енабле и користити Change Unit Enable да бисте укључили или искључили уређај.
3. Set occupancy inputs: choose how the controller determines occupancy (digital input, occupancy schedule via internal time clock, or BMS; or set always occupied/always unoccupied).
4. Adjust control parameters as needed: use the integral keypad display menus (e.g., temperature control/reset modes/setpoints, damper control, and fan parameters) to match the installed configuration.
5. Use remote access if available: use WebUI (included) via the building network, or use the optional remote display for monitoring and parameter adjustment.

The cursor always begins in the upper left corner of the display and will be
blinking. Press the button to move the cursor down for parameter adjustment.

Once the cursor has reached the desired parameter, press the buttons to
подесите вредност.

When satisfied with the adjustment, press the button to save the parameter.
When finished, make certain the cursor is in the upper left corner. If the cursor is
not in the upper left corner, the changes will not be saved. The cursor must be in
the upper left corner to enable screen advancement.

The initial menu screen displays the job name, unit tag, unit status, outside
air conditions, space conditions and setpoints.
Могући режими укључују:
Инпут Оутпут Статус
Displays real time conditions from sensors located in the unit and building space
if equipped with space mounted sensors. Controller output conditions can also
be viewед са овог екрана. До view the desired input/output point, the user must
select the desired channel. Reference the unit schematics for individual point

Статус заузетости
Displays current status of occupancy and the configured occupancy control
method and time zone.
Статус вентилатора за напајање
This screen displays the fan enable command, fan proving status, and the supply
fan ramp being sent from the controller to the VFD. The controller can modulate
the fan between the min and max speeds.
Space Thermostat Status
This screen displays the current temperature and relative humidity for up to four
space thermostats that are communicated to the controller via Modbus.

Статус издувног вентилатора

Статус издувног вентилатора
This screen displays the fan enable command, fan proving status, and the
exhaust fan ramp being sent from the controller to the VFD. The controller can
modulate the fan between the min and max speeds.
Airflow Status
This screen displays the current airflow volumes if the unit is provided with
airflow monitoring. Supply Fan, Exhaust Fan, and Outside Air airflow are optional
monitoring sensors that will appear when installed.
Ambient Lockout Status
Displays the lockout status for heating, cooling, economizing, preheat, and heat
pump heating based on the outside air ambient temperature. Ambient lockouts
for heating and cooling can be altered by entering Main Menu/Ctrl Variables/Temp
Контрола.
Outside Reset
This screen will be active if the controller is configured for outside air reset. The
heating and cooling devices modulate to maintain the supply air temperature
setpoint as determined by the outside reset calculation.
Supply Setpoint
This screen is active when supply temp control is selected or the active mode of
control. Displays current supply temperature and supply temperature setpoint to
be achieved.
Економајзер Рamp
Економајзер рamp screen will be active if the unit is configured for economizer
control. This screen displays the economizer setpoint, supply air discharge
temperature, economizer ramp status, and economizer control mode. Economizer
control mode options include, outside dry bulb, outside enthalpy, comparative dry
bulb, and comparative enthalpy.
Active Reset
This screen will be active if temperature control mode is set for space or return
air reset. The supply temperature setpoint is calculated based on the active
setpoint and the current space or return temperature. The calculated setpoint is
scaled between the supply temperature min and max setpoints determined by the
current mode of operation.

Case Heat
When the unit is off or in standby, the hot water valve will be modulated to
maintain the case temperature to the case heat setpoint.

Мени контроле температуре омогућава кориснику да view and adjust temperature
control conditions of the unit. Economizer setpoint adjustment is also found at
this location if the unit is equipped with outside air and recirculation dampерс
Reset Modes for Temperature Control
Reset Mode selections are available for both occupied and unoccupied operation.
Unoccupied Reset Mode is available when Unoccupied Reset Mode is selected to
Normal Operation or Recirculation with Unoccupied Setpoints. The Unoccupied
Reset Mode will hide when Night Setback or Off is selected for Unoccupied Unit
Операција.
Setpoint Selections:
Supply Temp Control – The supply discharge setpoint is a constant value (e.g.
72°F). Reference Temperature Setpoint screen for setpoint adjustment.
Space Reset – The controller will reset the supply air temperature setpoint to
maintain the space temperature setpoint (requires space temp sensor). Reference
the Temperature Setpoint screen for space setpoint adjustment.
Return Reset – The controller will reset the supply air temperature setpoint to
maintain the return air temperature setpoint (requires duct mounted return air
temp sensor). Reference the Temperature Setpoint screen for return air setpoint
прилагођавање.
OA Reset – The controller monitors the OA temperature and adjusts the desired
supply temperature setpoint accordingly. For example, when the OA is below
55°F, the controller will change the supply setpoint to 70°F. If the OA is above
65°F, the controller will change the supply setpoint to 55°F. If the OA temperature
is between 55°F and 65°F, the supply setpoint changes according to the OA
reset function. A visual representation of the OA reset function is shown below.
Reference Outside Setpoints for min and max outside air limits.
