Note: The iGrow1600/1800’s default settings for PID should be suitable for most any installation, and therefore
should not be modified without a good understanding of PID controls. If you feel a change is necessary
and are not sure how to proceed contact your local distributor, or Link4 directly, for assistance.
Note: You can also disable the zone temperature control loop. This is useful if you want to set a fixed water
temperature. Set the Min and Max water temperature to the same number and disable the zone
temperature loop.
PZone (Micro-Zone) for Proportional Equipment *
PZone (Proportional Device Micro-Zones) are special purpose mixvalves that control Micro-Zones (changes
made). A Micro-Zone is a region or compartment within a greenhouse that has a different temperature setpoint,
and is controlled by a hot water mixvalve heating system. In this system the iGrow1600/1800 measures the
Micro-Zone air temperature, and the hot water supply temperature. The iGrow 1600/1800™ can be used to
monitor and control up to two (2) independent heating PZones.
Note: This equipment type requires 2 consecutive channels 1&2, 3&4, 5&6, etc. The first channel (odd
numbered) must be wired to OPEN the valve, and the other (even numbered) to CLOSE it.
* Note: In some versions PZone may be shown as MZon2

Settings on the first screen are for the Supply water coming from the MixValve to the Micro-Zone area.
Temp
The Temp1 setting tells the iGrow1800™ which temp probe is being used to measure the hot water supply to
the greenhouse. Since you can have up to 5 temp probes connected to your iGrow1800 be sure to set this to
the correct one. Use the + or – buttons to select the correct probe.
Min
Min is the minimum water temperature of the supply pipe. If the supply water temperature ever goes below this
value the mixvalve will adjust increase the supply water temperature. Use the + or – buttons to select the
correct temperature.
Max
Max is the Maximum temperature that the supply water should ever become. If the supply water temperature
ever approaches this value, the mixvalve will adjust low the supply water temperature. This is especially
important when PVC pipes are being used. Use the + or – buttons to select the correct temperature.
Open Time
Open Time is the time it takes for the Mixvalve to go from fully opened to fully close. Measure this time with a
watch, add a few seconds, and then enter it into Open Time field.
