The Innotech Modular Thermostat is a device designed to control temperature in air conditioning systems. It is an analogue controller that regulates temperature of a conditioned space by switching heating and cooling systems as required. Tailoring of the control algorithm is made via screw adjustments that are accessible on the front panel. A knob on the center of the front panel sets the desired temperature. The current temperature and the desired temperature are displayed on a four digit display. The Set Point View button toggles between the two. The unit is DIN rail mountable, and has terminals for all external connections.
