A simpler way to control your greenhouse. The TLC has 5 cooling stages allowing for the opening of vents or curtains at an intermediate stage between low and high speeds on two-speeds fans to reduce vent cycles and extend vent motor life.
Stage 1: Cooling. Low speed on 2-speed fan, shutter open. Stage 2: Cooling. Vent/Curtains Open Stage 3: Cooling. Shutter closed, two-speed fan on high. Stage 4: 1-speed fan on, HAF fans off. Stage 5: Evaporative cooling on. Heat Stage: Heater on.
