C O N N E C T I O N S C H E ME For more details, please refer to Quick Setup Guide. CAUTION iGS-221 THE EQUIPMENT(S) PLUGGED TO THE IGS-25 OUTLETS AND CONTROLLED BY THE IGS-221 MUST HAVE THEIR OWN OVERHEATING PROTECTION BREAKER OR APPROPRIATE DEVICE © 2010-2011 - Nova Biomatique inc.
CONNECTION INSTRUCTIONS CONNECTING THE CONTROL MODULE TO THE CONNECTION MODULE Connect the two wires cable from the connection module (Input 1) to the control module’s terminal block. The red wire connected to the right terminal; the black wire to the middle terminal. Connect one of the Ethernet cable’s (RJ45) male connector into the female connector located underneath the control module and the other male connector in the connection module’s female connector (Input 2).
For an AC unit without “Auto restart”, plug it independently from the iGS-221 and set both the air conditioner and the iGS-221 to the desired garden temperature. A temperature sensor’s calibration is suggested on your iGS-221 so both devices have equivalent temperature readings (see Relative humidity and temperature sensors calibration on page 25).
3. SETTINGS AJUSTEMENT CONTROL PANEL DESCRIPTION 4 digits display: The display shows different data: current room conditions, time, control module’s settings and more.
I N IT I A L I Z A T I O N When the controller is initialized, the following elements appear on the display: The model (e.g.: P221) followed with the controller’s version (e.g.: S1.10); Then, the time followed by an informative message (Adv), indicating that the controller was unplugged for a while. For more information, see the Displayed Messages and Solutions section on page 21.
Differential adjustment The iGS-221 has a dynamic differential that is automatically self-adjusting to the growing environment. It is recommended to use this type of differential for CO 2 control and to resort to manual adjustment only if the differential’s functioning is not satisfactory. For more information, see the Differential section on page 15.
Altitude adjustment The precision on the CO2 concentration measurement is affected by the altitude; the concentration measurement drifts from the true value with altitude elevation. To assure a precise measure, it is recommended to adjust the controller to the garden site altitude relative to sea level. Once the light indicator is on at [Operating Mode]: Press MODIFY again; the letter “A” (for altitude), followed by a numerical value, appears on the display.
R E LA T I V E H U M I D IT Y S E T T I N G S A D J U S T ME N T [ % R H ] To adjust the set points for this parameter [% RH], repeatedly press SELECT SENSOR until the light indicator is on at [% RH]. The display shows the current relative humidity measurement. A flashing display means that an output associated with this parameter is active. To adjust the functions related to relative humidity, press MODIFY. The light indicator is on at the selected function.
[OPERATING MODE] Use ventilation to limit excessive humidity Once the light indicator is on at [Operating Mode]: “FC_?” for “FAN CONTROL”. appears on the display. Using either ARROW keys toggle “FC n” for no control or to “FC Y” to have the fan(s) activated if the relative humidity gets too high. Press MODIFY to save the modification and continue with the relative humidity’s alarm low limit (L) adjustment.
T E MP E R A T U R E S E T T I N G S A D J U S T ME N T [ T E MP ° C / ° F ] To adjust the set points for this parameter [Temp °C / °F], repeatedly press SELECT SENSOR until the light indicator is on at [Temp °C / °F]. The display shows the current temperature measurement. A flashing display means that an output associated to this parameter is active. To adjust the functions related to temperature, press MODIFY. The light indicator is on at the selected function.
Differential adjustment For more information, see the Differential section on page 15. Once the light indicator is on at [Night Setpoint]: Press MODIFY again and hold down until the letter “L”, followed by a numerical value, appears on the display (approximately 3 seconds). The light indicator will flash at [Differential]. To adjust the low differential (L), press the ARROW keys to modify the current value; hold down the key for a faster scroll of the values.
[24-HOUR LOG] Access to the 24 hours log For more information, see the 24 hours log section on page 16. Once the light indicator is on at [24-Hour Log]: The display shows a definite time (clock) and the following elements for that specific time: o “Lo”, followed by a numerical value corresponding to the lowest temperature level measurement. o “avg”, followed by a numerical value corresponding to the average temperature level measurements.
To set the time Repeatedly press SELECT SENSOR until the light indicators are simultaneously on at [% RH] and [Temp °C / °F]. Press MODIFY to select [Day Setpoint / Time]. Press the UP ARROW key to set the hours; hold down the key for a faster values scroll. Press the DOWN ARROW key to set the minutes; hold down the key for a faster scroll. Press MODIFY to save the settings and proceed to the cyclical fan setting Please note that the controller uses a 24 hour clock (e.g.: 13:00 = 1:00 pm).
Dynamic differential: recommended for CO2 control After each ON cycle of an equipment used for CO2 concentration control, the controller compares the value obtained with the set point. If the difference is too important (set point has not been reached or has been exceeded), the controller modifies its differential to minimize the difference at the next ON cycle.
A LA R M In order to be informed of any problem with the relative humidity or temperature control, it is possible to designate low and high limits for these parameters to trigger the alarm of the iGS-221. As soon as the ambient conditions drop down lower than the low limit or exceed the high limit, the alarm will be activated: a message (Alr X) will be displayed and the dry contact on the alarm connector (connection module) will be activated as well.
Alarm mode adjustment (A or B) Repeatedly press the SELECT SENSOR key until the light indicator is on at [Temp °C / °F] or [% RH]. Repeatedly press the MODIFY key until the light indicator is on at [Operating Mode]. The letter “L”, followed by a numerical value, is displayed. Press MODIFY again and hold down the key until the letter “A” or “b” appears on the display (mode A or B). The light indicator is flashing at [Operating Mode]. Press the ARROW keys to select the alarm mode.
4. SEQUENCE OF ACTIONS To control the different equipments plugged in the iGS-25, the iGS-221 uses a non modifiable internal programming. This programming allows the controller to intelligently manage the 6 equipments, prioritizing a logical sequence of actions. The following table sums up many possible situations and the outputs that will be activated in each case. The controller constantly monitors the situation and chooses the correct action as needed.
Example: Dehumidifying, heating: C1 5 min B2 In a growing environment, the relative humidity level is too high and the temperature is too low; the iGS-221 is in a situation where it needs to dehumidify and heat. First, the controller will activate the heating equipment (C1).
5. DISPLAYED MESSAGES AND SOLUTIONS I N FO R MA T I O N ME S S A G E S ( A D V I C E ) Code Cause Effects on controller Adv 1 The CO2 measurement exceeds 5000 ppm. Ventilation (output A2) is activated until the CO2 concentration drops below 5000 ppm. Then, the message disappears. If the CO2 sensor’s measurement seems false, it is possible to calibrate it. See CO2 Sensor Calibration section on page 23. Adv 2 The last CO2 sensor’s calibration has been done over a year ago.
E R R O R ME S S A G E S Code Cause Solution Err 1 A key from the keyboard is pressed at power up. If a key is stuck in, call technical support at 1 888 577-6274. Err 3 CO2 sensor is defective. Err 4 Temperature/humidity sensor is defective. Disconnect and reconnect the controller or do a reset. See Reset Procedure at the end of this section. If the problem persists, call technical support at 1 888 577-6274. Err 6 Automatic recovery has failed after intermittent fault.
6. SENSORS CALIBRATION The iGS-221 includes 3 climate sensors: one for the CO2, a second one for temperature and a third one for relative humidity. Each of them can be independently calibrated without affecting the others. CO2 SENSOR CALIBRATION Do you need to calibrate the CO2 sensor? The CO2 sensor is normally factory calibrated for a 1 to 5 years period.
Outdoor calibration For lack of using the two methods above, you can calibrate your CO 2 sensor outdoor, but take note that this method is not precise. We suppose an average exterior air CO2 concentration of 400 ppm. However, depending on the location and the time of the day, the real CO2 concentration in the air is between 350 and many thousands ppm.
R E LA T I V E H U M I D IT Y A N D T E M P E R A T U R E S E N S O R S C A L IB R A T IO N Do you need to calibrate your relative humidity or temperature sensors? Relative humidity and temperature sensors are factory calibrated. They are built to preserve their precision for their lifetime. We recommend not to calibrate these sensors, even if it is possible to do so without damaging them. In general, these sensors require calibration only if you wish that two separate controllers display the same reading.
7. SECURITY AND M AINTENANCE A IR F I LT E R The controller is equipped with an internal fan that allows a faster air sampling. Do not expose the venting slits to potential sources of humidity or dust. These slits located under the control module are protected by a dust guard filter that should be there at all times. We recommend to regularly clean or replace the dust guard filter to improve the controller’s effectiveness and its length of life. To remove the filter, lift up the black plastic cover.
E LE C T R I C A L S P E C I F I C A T I O N S IMPORTANT: Each iGS-25 can support a maximum of 15 A. In order to take advantage of 15 A for each iGS-25, it is important to use 3 electrical outputs on 3 separate electrical circuits. The equipments’ total load must not exceed the electrical circuit capacity.
8. WARRANTY Nova Biomatique, Inc. (hereafter NBI) offers a 3 year warranty from the date of original purchase by the end-user (proof of purchase required), applicable to defects in material and workmanship for the control module (iGS-221), the connection module and the iGS-25. All guarantee claims must be submitted directly to NBI by the retailer or end-user (1 888 577-6274).
THE IGS-DCS - DRY CONTACT SWITCHER The iGS-DCS is a switch relay that operates from a standard 110-120V electrical output. It activates a control loop that can operate air conditioning unit, heat pump, ventilators, humidifier, dehumidifier or “2 wires” devices connected to a less than 90V ac circuit or a 24V dc circuit. The iGS-DCS, when connected to a 110-120V climate controller’s output, replaces any thermostat or hygrometer equipped with “2 wires”.
