Thermostat control keys



Place your room thermostat in a room where you most use it as your
living area. For example: living room. Avoid installing the room
thermostat where there is a lot of air circulation such as door entry or
window edges. Also, do not place in places near heat units (central
heating system, fireplace, etc.) and places that receive direct
sunlight. We recommend that the room thermostat be placed at an
altitude of 50 cm to 150 cm from the floor. You can try a few places to
find the most suitable place.
