  • Page 7: Before You Begin

    Before you Begin Temperature Control With the iGrow Series 100™ you can program a cooling temperature target called a “Cool Setpoint” and a heating temperature target called a “Heat Setpoint”. The temperature range between these two targets is called the “Normal” temperature range or stage. If the greenhouse temperature is within the Normal temperature band usually none of the cooling or heating equipment is on. However, some circulation fans (often called horizon- tal air flow (HAF) fans) may be active to maintain air movement within the greenhouse environment. Whenever the temperature within the greenhouse moves above the cool setpoint, or below the heat setpoint (falls outside the Normal temperature range) the iGrow Series 100™ will enter cooling or heating stages to bring it back in line. With the iGrow Series 100™ you can program up to six cooling and two heating stages. These stages go from Cool 1 to Cool 6 and Heat 1 to Heat 2. Cool 1 and Heat 1 are the least aggressive with Cool 6 and Heat 2 the most aggressive. In your program you will determine what equipment you want to be active in each of the stages. When the air temperature in the greenhouse rises above the Cool Setpoint, the system enters the first stage of cooling, referred to as Cool 1. If the temperature continues to rise, the system will enter the second stage, Cool 2, then the third stage, Cool 3 and so forth. At each increasing cooling stage, more cooling will be brought to attempt to bring the air temperature below the cool setpoint and within the target “Normal” temperature range. Heating works the same way. In considering the difference between each heating and cooling stage there is a variable in the program which is the number of degrees between each heating and cooling stage called the “Stage Separation” or ‘Stage Width”. Whenever the temperature rises above the cool setpoint, the iGrow Series 100™ will activate the appropriate equipment to bring the greenhouse to the normal temperature range. If the stage width is 1 degree and the temperature rises 1.1 degrees above the cool setpoint, then the controller will be active in C2 cooling stage. The same goes for the heating stage when the temperature drops below...

  • Page 8: Deadbands

    Deadbands If the temperature is below the cool setpoint and rises into the first stage of cooling, some cooling equipment will be turned on. This may then lower the temperature and bring it into the normal range. In order to keep the equipment from oscillating, a “Deadband” is employed when the temperature is between stages. In Figure 1.1 the dead band is set at 1 degree so that when the greenhouse is attempting to return to Normal temperature from C4 to C3 the controller will use a deadband of 1 degree to keep the equipment from oscillating off and on. Now, when the temperature drops below the cool setpoint, the system remains in the Cool 1 stage until the temperature drops below the Cool Deadband. The concepts that we described for cooling operate in the same manner for heating. Setpoints You will be able to use up to 3 setpoints in a 24 hour time period. Within each twenty- four hour period Setpoints are based on time and temperature to produce the deisred environment. By placing setpoints during different times of the day you can regulate the temperature within a range for target temperatures and humidity (humidity sensor sold seperately). When a setpoint is in effect at a certain time length the controller will acti- vate the necessary equipment in heating and cool stages to bring the environment back to Norm. The same applies when the humidity rises or falls beyond the target low/high setpoint. When one or more setpoints are used the second or subsequent setpoints will become the active setpoint at the start time and the previous setpoint will end. Ramping In addition, you have the option of a temperature ramp between the setpoints. Each set- point time period begins with a Ramp time. The benefit of ramping allows you to make smooth transitions within the greenhouse so that the plants don’t experience tempera- ture shock. Ramping also saves energy, which translates directly into lower operating costs. In the example on the following page (Figure 1.1), the start time is 8:00am with a 60 min- ute ramp time. The ramp time enables a smooth transition of the target temperatures between the setpoint time periods. Of course, the ramp times can be set to 0 and in this case there will be an immediate step transition in the set points. Figure 1.1 also shows a...

  • Page 10: Control Strategy

    Control Strategy Prior to installing and programming the iGrow Series 100™ it is important to determine an overall strategy to control the environment in the greenhouse. The iGrow Series 100™ is an extremely flexible and powerful device, thus additional care and planning are required. In order to aid you with the process, Link4 has provided several worksheets in the follow- ing pages. It is assumed that you already possess a general understanding of greenhouse controls. If not, please review this section carefully. It is recommended that you make copies of these sheets before using them. They will be useful in the future should your control needs change.

  • Page 15: Wiring The Igrow Series 100

    Wiring the iGrow Series 100™ Warning: Do Not Plug-in the Power while wiring the iGrow Series 100™ and keep the manual override switches in the OFF position. It is recommended that all connections be made through liquid tight connectors at the bottom of the iGrow Series 100™. These glands compress around the cables to form a watertight seal. Making any additional holes in the top, sides, or back of the enclosure can result in water condensation inside the unit, causing damage to the controller. Failure to install to Link4’s specification will void the warranty. In preparation for the control wiring you should decide the iGrow Series 100™ output as- signments and control strategy. For more information on output assignment and control strategies, please refer to the Control Strategy section and the appropriate worksheets for this manual. Power Supply Installation 1. If you want to navigate through the iGrow Series 100™ to see some of the features and to familiarize yourself with how it works, begin by installing the power supply.

    8. Now, if needed, you can plug in the power to navigate through the iGrow Series 100™. If you continue to install different outputs or inputs remember to keep the power supply unplugged. Figure 3.1 Wiring the Power Supply Output Installation The general installation strategy for this section is to install the output equipment in the greenhouse first and then the inputs to keep the cables organized in the iGrow Series 100™. It is assumed that at this point you have already planned the channel assignment.

  • Page 17: Control Relays & Contactors

    Control Relays & Contactors Your iGrow Series 100™ has 4 or 8 output relays that are provided as dry contacts, i.e. switch closures. If an output is activated to ON, the switch is “closed” (shorted); and if it is activated to OFF, the switch is “open” (no continuity between the positive and negative terminals). The board mounted relays are intended as “pilot” relays. For most loads you will want the iGrow Series 100™ outputs to control a load relay or contactor that is connected to the motor. However, in some cases such as irrigation valves that are 24 VAC, you can drive them directly assuming that you are wiring only one or two valves per relay. The maxi- mum run current recommended for each of the iGrow Series 100 relays is 1 amp. “Dry” Contact Design “Dry” contact installation design is used when a user wants to isolate equipment and use transformers for every piece of equipment.

  • Page 18: Indoor Air Temperature Probe Installation

    The iGrow Series 100™ is shipped with a standard temperature probe. This sensor in- cludes 50-feet of sensor cable. Normally you will want to hang the sensor near the crop level close to the center of the controlled environment. It is important to keep the sensor away from irrigation emitters, unit heaters, etc. that will effect the accuracy of the sensor. 1. First, open up the front door, as shown in Figure 2.3. 2. Find a central location in the greenhouse and let it hang relatively close to the height of where the plants will be. 3. Run the free end of the sensor cable to the controller unit. 4. You may extend the sensor cable as needed, but make sure to use an adapter and wire approved by Link4 to make any extensions (the wire and adapter can be pur- chased from Link4). It should be noted that the controller is calibrated for a 50 ft. temperature probe. If additional wires are added or removed, software calibration will be necessary to ensure proper temperature measurement accuracy. 5. Carefully insert the cable through the right most watertight fitting at the bottom of the enclosure. It is easy to strip insulation and/or break wires when pulling cable. If you want to bundle wires tighter, use UV protected “tie wraps” (typically blue or black), and do not over-tighten. Note: If any splices are needed to extend cable length, make certain they are WATERTIGHT. Water or fertilizer infiltration WILL cause unstable sensor readings.

Initial Settings This is where you go for the first time to define the type of equipment on each channel that you are using and to name the channel. 3.1.1.2.1. Set Type There are three types (classes) of equipment that you can program. One is On/Off and the other two are “proportional” or Vents and Curtains. 3.1.1.2.1.1. General Type Select this option when you want to setup the channel 3.1.1.2.1.1.1. On/Off On/Off equipment such as fans, louvers, heaters, etc., are sometimes referred to as digi- tal outputs. This equipment type occupies only one channel and can be programmed on any channel. 3.1.1.2.1.1.2. Vent A vent with a drive open and drive close relay requires two consecutive channels. The first must be an odd number and the second, its neighbor to the right, an even number. Acceptable pairs are 1&2, 3&4, 5&6 and 7&8. The odd numbered channel opens the vent, the even number closes the vent. A vent is a proportional device, sometimes referred to as a “timed analog output”. 3.1.1.2.1.1.2.1. Open to Close Time 3.1.1.2.1.1.2.1.1. Set Open Time The “Open Time” is the time in minutes and seconds that it takes for the vent to go from its full close position to full open position. 3.1.1.2.1.1.2.2.

Wind Set Vent Open Limit This is the maximum percent open for the vent when the wind speed exceeds the limit set next. The program calculates the average wind speed over the last 3 seconds. This is to eliminate responding to short wind gusts. Set Wind Speed Limit This is the wind speed at which the vent will be closed to the Vent Open Limit previously programmed. The wind override ends when the wind speed falls below the threshold for two minutes. 3.1.1.2.1.1.2.2.3. Outside Temp In the event that it is very cold outside you may want to limit the percentage opening of the vent regardless of the inside zone temperature. Set Vent Open Limit This is the maximum percent open for the vent when the outside temperature falls below the threshold set in the next entry.

Enable Shock Protection Enabling Shock Protection forces the curtain to open slowly in the morning when the outside temperature is below a certain threshold. This is to avoid the in-rush of cold air that may be above the energy curtain. In the morning when the curtain is scheduled to open and if the outside temperature is below deg, the curtain will open in four steps. It will open 5% and then pause for 5 minutes. It will repeat this 4 times and then open to 0% without stopping. 3.1.1.2.1.1.3.7.

For example, you may want to dehumidify but if it’s very cold outside, you may want to turn on the heat instead of open a vent and turning on a fan. This humidity settings option can be useful in other applications even if you do not have a humidity sensor. For example, you may want to do misting control with a particular output, You can set up a “software” humidity sensor, a humidity time window and threshold so that the cycling will take place during your selected time period. 3.9.3. Stage Delay This time setting in seconds is the shortest time permitted for switching between tem- perature stages. A typical value here would be 60 to 120 seconds.
