The D-135ES series thermostat is a stand-alone microprocessor based thermostat with large LCD display that takes the guess work out of reading the temperature. The D-135ES maintains highly accurate temperature control without the programming hassle. The thermostat is designed to control room temperature by way of on/off controlling the heating (and cooling) equipments. The setpoint is displayed and can be changed easily by pressing up or down arrow button. This simple to use accurate thermostat will replace most round, square or rectangular thermostats. D-135ES is environmentally safe, mercury-free which requires no leveling, so there’s no hassle, and no special disposal requirements.
