Cascade Communication - Watts AERCO Edge [ii] Operation Manual

Edge [ii] Controller Operation Manual
SECTION 6 – ADVANCED SETUP
VSP Pump Speed Adjust: Use this parameter to adjust the voltage
▪
signal to achieve the desired pump speed. For example, setting to 110% will
change the signal from 5.0V to 5.5V. (Range: 80 to 120%)
VSP Pump Off Delay: Specify the time delay after the unit stops firing
▪
before shutting the pump off. (Range: 1 to 600 secs.)
VSP Pump Output: The voltage signal sent to the pump (read-only).
▪
VSP Pump Relay: Displays if pump is On or Off
▪
o The following parameters appear only if VSP Pump Mode = Fire Rate:
VSP Piping Configuration: Depending on the configuration of the plant,
▪
choose either 1 Pump Per Blr or 1 Pump Per Plnt.
Boiler Plant Size: Specify how many boilers are in the plant.
▪
(Range: 1 to 16)
Plant VSP Pump min spd: Specify the voltage that will drive the pump
▪
at its minimum speed. (Range 0 to 10.0 V)
Plant VSP Pump max spd: Specify the voltage that will drive the pump
▪
at its maximum speed. (Range 0 to 10.0 V)
Rem Blr VS Pump Add: Specify the address of the boiler to which the
▪
variable speed pump is connected. (Range: 1 to 16)
o The following parameters appear only if VSP Pump Mode = Return Temp:
VSP Pump Decrease: Specify the amount the voltage signal will
▪
increase/decrease for every VSP Pump Decr Time interval.
(Range: 0 to 100%)
VSP Pump Decr Time: Specify the interval at which the VSP Pump
▪
Decrease signal is sent to the pump. (Range: 1 to 600 secs.)
VSP Pump Incr Time: Specify the amount of time for voltage signal to
▪
the pump will reach full speed when Setpoint Limiting or High Temperature
occurs; this overrides VSP Pump Decrease and VSP Pump Decr Time.
When Setpoint Limiting or High Temperature condition ends, the VSP Pump
Decrease and VSP Pump Decr Time resumes. (Range: 1 to 600 secs.)
