check room thermostat

RS100 with outdoor

sensor (Room sensor-On)

outdoor temperature is higher than 70°F, depending upon the Eco-temperature set (70°F is the default). Check Info chapter Step 7 or temperature is higher than the Eco temperature set (see RS100 installation instructions).

Check timer program and set room temperature
