The iGrow800 output relays are provided as dry contacts, switch closures. If an output is activated to ON, the switch is “closed” (shorted); if it is activated to OFF, the switch is “open” (no continuity between the positive and negative terminals).

Per – RELAY

Max Voltage – 24V

Max Current – 1 AMP

The board mounted relays are intended as “pilot” relays. (NO VOLTAGE)For most loads you will want the iGrow outputs to control a load relay or contactor that is connected to the motor.

However, irrigation valves that are 24 VAC, you can drive them directly assuming that you are wiring only one or two valves per relay. The maximum run current and voltage is 1 Amp / 24 volts

iGrow800 – Relay Output Design and Understanding

1-Wet Wiring Example1 – 24v Transformer source powering multiple Outputs

for controlling multiple control relays

2 - Dry Wiring Examples2 – 24v Transformer each Powering

its own dedicated output for controlling a single piece of

equipment. Common for heaters & Chill systems which have there own

24v thermostat control source

1 – Proportional Dry wirng for Motor Controller Example

1 Paired set of Outputs powered by 24v Transformer from motor controller. 1st output for Open

& 2nd output for Close signal

iGrow800 – Relay Output Design and Understanding

Note: for Proportional equipment using 2 outputs you would have to use an Odd/Even pair of adjacent outputs1-2, 3-4, 5-6 etc..

iGrow800 – Sensor Calibration

Next / Previous allows you to toggle thru the different sensors you have installed

Editallows you to calibrate and change the sensor

value

RAW: Is what the sensor actually reads

CAL: is the increase/decrease amt you want the sensor to change

ADJ: is the sensor value that will be displayed on home screen, as well as the value the controllers programming will respond to.

iGrow800 – Setpoint Understanding

Cool Setpoint - if the temp goes above this threshold it will enter cooling stages to bring the temp back in line within the Normal temp range (you can have up to 6 cool stages)

Heat Setpoint - if the temp goes below this threshold it will enter Heating stages to bring the temp back in line within the Normal temp range (you can have up to 2 heat stages)

Humidify Setpoint - if the RH reading is below this parameter, the condition is considered too dry, and the system will go into the humidification stage.Dehumidify Setpoint - if the RH reading is above this parameter, the condition is considered too damp, and the system will go into the dehumidification stage.

C02 Setpoint - if the C02ppm level is blow this parameter, the condition will be Low C02, and the system will start injecting C02 until it reaches the Setpoint plus Deadband.Note:* Temperature, Relative Humidity, and C02 can have up to 3 setpoints in a 24-hour time period.* Start Times set for setpoints are the same for Temperature, Relative Humidity, and C02

You can program setpoints for

Temperature ~ Relative Humidity ~ C02

You can program Setpoint Times for

Day ~ Night ~ DIF (or the difference between day & night)
