problem
guests arrive at an unfamiliar rental and face a thermostat they've never seen before. too cold, too warm — they adjust blindly, overheat the space or waste energy. the host gets complaints. the next guest walks into the wrong temperature.
solution
one laminated card next to the thermostat — how to switch between heating and cooling, how to use the + and − buttons, and the ideal temperature range. every guest comfortable from day one, no messages to the host, no wasted energy.
