1.8. Sensor Options:
The sensors are used for energy measurement and system monitoring. Both flow and pressure
sensors can be used.
1.8.1. Impulse Flow Meter
The flow can be measured using a mechanical flow meter (if installed).
x
If impulse flow meter is installed (on
T6 / PF
) select “
Yes
”, then you must use
(+)
or
(-)
to enter
the flow meter characteristics in gal / impulse. (Adjustable 0.26 to 6.6 gal/imp
with factory value 1.0 gal/imp).
x
If no flow meter is installed (factory default setting) you must manually enter the
maximum pump flow in gallons/minute using the
(+)
or
(-)
buttons. The manufacturer’s
specification is generally found in the pump literature or on the manufacturer’s website.
1.8.2. Grundfos Flow Sensor (GDS1)
The controller has 2 dedicated inputs for analog GRUNDFOS sensors (Type VFS Flow
sensor or VPS pressure sensor).
x
The Flow sensor is used for energy measurement and monitoring
x
The Pressure sensor is used only to monitor the pressure on the primary circuit.
GDS1
may be connected to either a flow or pressure sensor.
