Web4. Dual enthalpy sensors in outside air and return air shall allow the economizer co ntrollers to switch to an economizer mode of operation anytime the outside enthalpy is less than the return air enthalpy. 5. An outside air only enthalpy sensor shall allow the economizer to enable the economizer package any- WebA humidistat or hygrostat is an electronic device analogous to a thermostat but which responds to relative humidity, not temperature. A typical humidistat is usually included with portable humidifiers or dehumidifiers. It can also be included with combined air cleaner or humidifier units to control a home's humidity level or any other indoor space.
