The UpCart decreases pressure applied on supporting surfaces, improves stability, is capable of walking over curbs and stairs, decreasing pull/push forces especially for moving over the irregular terrain, and improves storing and carrying in the folded state.
When the thermostat says âwaitâ in means the system is in compressor protection mode due to a power failure or short cycling due to you turning the temperature up and down real quick trying to turn the system off and on and off again. Matthew: This compressor protection time is 5 mins.
A thermostat is an instance of a  bang-bang controller  as the heating or cooling system output is not proportional to the difference between actual temperature and the set temperature; the equipment runs at full capacity until the set temperature is reached, then shuts off.
