iGrow1400 - Micro Zone Programming
The iGrow 1400™ can be used to monitor and control up to five (5) independent heating or cooling “Micro-Zones”. What is a Micro-Zone? A Micro-Zone is a region or compartment within a greenhouse that has a different temperature setpoint. Typical uses for Micro-Zones would be bench heating, corridor heating, or any other area in the greenhouse with separate heating or cooling equipment. Any of the iGrow1400’s 12 outputs can be programmed as an M-Zone. An MZone output is basically an independent thermostat with both a day and night setting.

Note: In order for you to use Micro Zone you must first have a Temp Probe Installed on the controller
Note: MZones only control On/Off type equipment’s. For control of proportional type see Pzone.
To program from the home screen hit Enter/Menu -> Program Equipment -> Hit Enter/Menu to highlight Output -> NEXT to scroll over to Equipment type filed -> hit + till you display MZone then hit Back.
The first option for MZones is setting it to control either a heating device or a cooling one. The next setting is telling the iGrow1400™ which temperature probe to use. The iGrow 1400™ has five temperature probe sensor inputs, so it’s important to set the iGrow1400™ to read the correct one for the MZone.
Two target temperatures can be set, one for Day and the other Nite. Either can be Enabled or Disabled. The Day temperature target begins with the Start time. The start can be astronomically adjusted by pressing the + key when the cursor is positioned over at. The iGrow 1400™ will keep the device on so long as the following two conditions are met: 1. The current cooling/heating stage is less than or equal to the indicated stage, where H6<H5…<N<C1<….C6. 2. The temperature is above/below the target temperature plus the deadband
The Nite target is set exactly the same as the day. If only one temperature setpoint is desired for the 24 hour period, then you can simply select the Disabled option for the second one.
In the example screen above, iGrow1400™ output 7 is controlling a Bench Heater. From 6am to 8pm the heater will turn on if the MZone temperature goes below 72°F. Additionally, it will shut off, or Lockout, if the main greenhouse enters Cool1-Cool6. This way you’re not trying to heat and cool your greenhouse at the same time. From 8pm to 6am the setpoint lowers to 65°F and will also Lockout if the greenhouse enters Cool1-Cool6.
