Route all control conductors separately from sensor conductors. This is very important to
reduce electrical interference. Control conductors may be routed in conduits that contain
other power system wiring only if the insulation material on the control conductors is the
same as that of the power system wiring. Consult the national electrical code or local codes
if in doubt about the insulation ratings of the wire in use.
NOTE: WHEN FIRST SETTING UP AND BEFORE PROVIDING POWER TO
THE WATER PRO, MAKE CERTAIN ALL OF THE ON/OFF/AUTO SWITCHES
ARE IN THE OFF POSITION. THIS APPLIES TO THE WATER PRO AS WELL
AS THE WATER PRO EXPANSION MODULE.
INSTALLING THE UNIT
The WATER PRO should be installed as close as possible to the crop area to be controlled.
The VPD Sensor is hung above and in the center of the crop area. Make sure the sensor is
mounted so that no water hits the sensor or can be sucked into the fan. The Photocell Light
Sensor is built into the WATER PRO enclosure.
INSTALLING A WATER PRO EXPANSION MODULE (OPTIONAL)
1. CAUTION! First Turn the WATER PRO unit OFF.
2. Connect the conductors from your solenoid valves (24VAC type) to the WATER PRO
EXPANSION module plugs.
3. Make sure all plugs are secured into the WATER PRO EXPANSION module then turn the
screw locking the panel in its enclosure and latch the Lexan door.
6. Make sure all ON/OFF/AUTO switches are in the
OFF
position.
**Refer to STATION SET-UP, to set up the new expansion stations**
INSTALLING AN ADDITIONAL VPD SENSOR (OPTIONAL)
1. Hang the VPD Sensor in the middle of the area to be controlled. If the distance from
the WATER PRO exceeds 100 feet, run a Sensor Extension Cable from the WATER
PRO and connect it to the VPD Sensor Cable.
2. Connect the VPD Sensor to the termination connector on the back of the
WATER PRO.
Consider purchasing a second VPD Sensor for the following reasons:
1. More thorough sensing control of the watering area or zone is needed.
2. Additional greenhouse watering area/zones to be controlled.
3. Back-up.
INSTALLING A GROWLINK PC CONTROL CABLE (OPTIONAL)
1. Run the communications cable from the PC location to the WATER PRO. This is a
special type of computer communications cable (RS-485) and the maximum distance
the WATER PRO can be from the PC is 5000 feet.
2. Connect the communication cable to the WATER PRO. Up to 32 WATER
PRO units can be linked on the communications line. The farthest WATER PRO in the
