Description
Schneider Electric TC903-3A4DPSA Thermostat is a device used to regulate and control the temperature of a system or an environment. It is commonly used in heating, ventilation, and air conditioning (HVAC) systems to maintain a desired temperature within a space. It typically operates independently and does not require a central system or smart home integration.
The thermostat has a Liquid Crystal Display with five buttons, likely for navigation and programming. The thermostat can connect to an external sensor to provide more accurate temperature readings or to control the HVAC system based on the temperature at a specific location. 4P typically refers to a four-pole connection, which may relate to the electrical wiring and compatibility of the thermostat.
The thermostat supports control for three different fan speeds. 240V is the voltage rating. It is designed to operate on a 240-volt electrical system. White is the color of the thermostat, which is often mentioned for aesthetic purposes or to ensure it matches the room's decor.
