Greenhouse HAVAC Atmo (ttr)

IC for controlling temperature, and water and CO2 delivery. It will keep temperature between 31C and 39C while desired is 34C. If current temperature is outside of 31-39, cooling/heating will work unitl 34 is reached. It will also top-up CO2 if below 15% (still breathable). IC housing will display percentage of CO2 in room. It will operate volume pump, if pressure after pump is bellow 2MPa. This is to keep hydroponics full with water. No memory needed for those settings - if you want to change, edit Variables section and write new code to IC10. Needed: - gas sensor - wall heater and cooler - active vent with CO2 pipe attached. - volume pump and pipe analiser (for water) Note: please have air outlet done somehow (like passive vent with back-pressure) to remove excess air. Note: if you have external cooling/heating system based on passive heat exchange, cooler (and/or heater) can be replaced for digital valve Note 2: Please prime system (especially atmo) manually to avoid unexpected issues. This is down to fact, that when heating/cooling sub-function is active, it does not monitor other functions. So it might start pumping water while being stuck inside heating and pipe will burst. During normal operation it should be fine as heating / cooling does not last long.
