Product Description
The IntelliStation
®
is electronic water mixing system providing
user-directed control and monitoring of water distribution sys-
tems. IntelliStation
®
includes an electronically actuated valve that
mixes hot water with cold water, temperature sensors (plus a
quick response temperature sensor), pressure sensors, check
valves, and a recirculation pump to maintain the recirculation
loop temperature (reducing wait time for tempered water to
reach point-of-use fixtures, saving water and energy).

NOTICE
Temperature sensor wires are non-polarized and can be con-
nected to either terminal for a given sensor. Pressure and flow
sensors are terminal specific and need to be wired according
to the illustration.
Only change one sensor at a time to reduce the potential of
connecting the wrong sensor to the wrong terminal.
Water quality can cause scale to build up on sensor housing.
Sensors may malfunction due to this scale and may only need
to be cleaned and not replaced.
It is good practice to use small stickers to “flag” each sensor
lead to better identify wires.
CAUTION
!
There are two types of pressure sensors used on IntelliStations, a
150psi and a 200psi sensor. Do not change sensor types. Doing
so will result in errors and improper operation.
Contact Tech Support to determine which sensor is installed on
your particular unit.
Sensor Care and Replacement
The following guidelines should be followed whenever servicing
any, or all, sensors on the Watts IntelliStation panel.
1. Disconnect the power supply from the IntelliStation panel.
2. Disconnect power to the circulator, if present. Circulators are
optional and may be powered through the IntelliStation or
they may be independently powered.
3. Close ball valves 1-5.
4. If replacing sensor, identify connection points for sensor
being replaced on main circuit board (see illustration).
5. Remove sensor from IntelliStation and disconnect from
circuit board.
6. Connect new sensor to circuit board and reconnect on
panel. Teflon tape should be applied to thread to ensure a
water-tight seal.
7. Repeat with each sensor needing to be replaced.
8. Open ball valves 1, 2, and 5 and let the system stabilize for
30 seconds.
9. Open ball valves 3 and 4.
10. Check sensors and verify no leaks are detected. If leaks are
detected repeat steps 3, 5–9.
11. Reconnect power to the circulator.
12. Reconnect power to the IntelliStation and turn on.
13. Verify no error codes are presented on the IntelliStation
monitor. Refer to the main IntelliStation Installation and
Operations Manual for error codes.
When the IntelliStation resumes operation there will be air in the
system. This will naturally diffuse out over time.
DANGER
!
Electricity, electrocution and shock hazards.
