    Comments about Robertshaw 9870i Programmable Heat Pump Thermostat, with Humidification/Dehumidification Control:

    I use this specifically to control temperature and humidity in walk-in basement. Works great. Allows for changing temp slightly at different times of day and week. One complaint is the lack of backlight button to read panel. Can't see panel in low light. No way to set contrast or light on panel. However, it installed easily. For the price I would definitly recommend.
