Choosing the non-programmable mode for the thermostat allow the
thermostat to run in a simplified mode that will satisfy heating or
cooling setpoints based on the setpoint value and mode chosen.
Operating the thermostat in a programmable mode allows the end
user to setup heating and cooling setpoints for 4 periods of each
day of the seven days of the week. The thermostat has default
heating and cooling setpoints. Changing the heating and cooling
setpoints and the transition times for the 4 periods with each day is
achieved only thorough the APP developed specifically for the
