Itâs a good sign that the leaves are still in rather good condition considering the root health. An orchid with minimal to no roots is worrisome, but we have lots of tricks we can try to get it to sprout new ones. In fact, my wife has been in this exact predicament with several of her rescue orchids. Root rot can happen so quickly sometimes. The good news is that you can still save an orchid with few to no roots!
If the temperature is higher that -20Â° vs. outside temp, look for areas where air may be getting in and heating the house. However, with the thermostat set to cool, the air coming out of the air escape should be between 45-60Â°F. Locate the vent. In some cases they may be on the floor, wall, or ceiling. For vents on the ceiling, the IR-IND allows you to gauge temperature (from a distance) as it leaves the vent.
Your Premium with the manual system should be able to deliver low 40's at the vent with everything set to max cold and recirc on. Just be aware that that will only last for 10 minutes. At the 10 minute mark the vent temp will ramp up to somewhere in the 50's. That ramped up temp may be what you are measuring.
