Contact thermostats are crucial devices in modern heating and cooling systems, playing a pivotal role in maintaining comfortable environments in both residential and industrial settings. These devices monitor temperature fluctuations and automatically control the operation of heating, ventilation, and air conditioning (HVAC) systems. In this article, we will explore how contact thermostats work, their types, advantages, and applications.
What is a Contact Thermostat?
A contact thermostat is a temperature-sensitive switch that utilizes mechanical or electrical contacts to regulate temperature. When the temperature reaches a predetermined set point, the thermostat closes or opens a circuit, either turning the heating or cooling system on or off. This simple yet effective mechanism ensures that indoor temperatures remain within a desired range, enhancing comfort and energy efficiency. How Contact Thermostats Work The core of a contact thermostat is a temperature sensor, which can be a bimetallic strip or a thermistor. In mechanical contact thermostats, a bimetallic strip bends in response to temperature changes. When it bends to a certain degree, it either makes or breaks an electrical connection, triggering the HVAC system.
