valent VPR Series User Manual

Valent Controls IOM 41 IOM-C1-0616
Part Number 474626
Air Flow Monitoring Type
Indicates if an air flow monitoring station is
installed, and the type of station.
Air Source Heat Pump Allow Defrost Mode
Indicates if defrost is enabled or disabled for an
air source heat pump.
Air Source Heat Pump Defrost Cancel Condensing
Setpoint
When the condensing temperature reaches this
setpoint, the unit will cancel the defrost mode
and resume normal operation.
Air Source Heat Pump Defrost Status
Indicates whether an ASHP unit in heating mode
is actively defrosting the outside coil by
changing from Normal to Defrosting, and also
indicates which portion of the defrost logic, if
any, is active.
If the unit is configured to operate without
defrost mode, this point displays Defrost
Disabled.
The number of defrost cycles in the last hour is
indicated by: 1x Defrost, 2x Defrost.
If the unit has switched to an auxiliary heat
source, this point displays the reason why:
 3x -> Aux Heat: Third Defrost cycle in a one
hour interval.
 Aux Heat: Defrost requested, but unit is
configured to operate without defrost mode.
 Low Sat -> Aux Heat: Failure to maintain
requested supply temperature.
 Low Amb -> Aux Heat: Ambient conditions
too cold to run as an Air Source Heat Pump.
If the unit is not an Air Source Heat Pump, this
point displays Not Installed.
Air Source Heat Pump Electric Heat Defrost
Indicates whether the Electric Heater is allowed
to operate during ASHP defrost mode.
Air Source Heat Pump Electric Heat Defrost Enable
A password is required to control this point.
Contact Valent for password.
Air Source Heat Pump Low Ambient Compressor
Lockout Setpoint
If the outdoor air temperature is below this
setpoint, the compressors are locked out from
heating and cooling.
Alarm Reset
This point resets all of the unit alarms.
Alarm Status
The status of the controller’s alarm output
(Digital Output 9). Digital Output 9 on the 34-
point module closes and the associated LED
lights up when any shutdown alarm is present in
the system. Refer to the Alarms section on page
54 for more information.
Ambient Cooling Lockout
Indicates the current status of the ambient
cooling lockout. If the outdoor air temperature
falls below the ambient cooling lockout setpoint,
mechanical cooling is locked out.
Ambient Heating Lockout
Indicates the current status of the ambient
heating lockout. If the outdoor air temperature
rises above the ambient heating lockout
setpoint, mechanical heating is locked out.
BACnet Time Synch
Consult the factory before adjusting this
parameter.
BACnet UDP Port
This adjusts the BACnet UDP port for special
BMS integration configurations (default 47808).
Bapi Space Sensor Enable
Enables or disables the use of an optional LCD
Space Temperature Sensor (Bapi Sensor).
Chilled Water Valve Position When Unit Off
Sets the position that the chilled water valve will
drive to when the unit is off. Configure the 10
Volts Opens Chilled Water Valve setpoint first.
CO
2
Control
Indicates whether or not the unit is configured to
control CO2 levels in the space.
CO
2
Damper Maximum Position
When CO
2
is above setpoint, this is the furthest
open the outdoor air damper can be controlled
to when this feature is active.
CO
2
Deadband
When the CO2 level is met, the CO2, in ppm,
must rise or fall by ½ the value of the deadband
before the damper will modulate once more.
