Room Thermostat Project

Room thermostat is a good electronics project which is used to control heating or cooling system in air conditioning and heating system has been one of the common device used in residential and industrial buildings to control the temperature of a space in a warehouse, a room, a hall or an office. This room thermostat project will focus on the chilled water control of a space that uses chilled water as its source of cooling. The controller basically consists of a comparator that controls the ON and OFF of the chilled water valve based on the sensor temperature.

Room Thermostat circuit


Above image shows the circuit diagram of room thermostat project which consist relay, thermistor, resistor, potentiometer etc. The control of the fan speed is usually hardwired with two speed or three speed motors and is incorporated into the thermostat. The temperature range of this thermostat is from 5 Celsius to 30 Celsius with a tolerance of approximately 3 degree Celsius. Hence, only non critical tolerance control of temperature control such as a room can be used.
