cooling device to dissipate excessive heat or heaters to prevent the formation of condensate or frost. Some enclosures require both.
But heating and cooling devices typically don’t need to run continuously. They need to be controlled, both to prevent overheating or overcooling
and to control energy costs.
Hygrotherms sense both temperature and relative humidity and start a heater if the temperature falls below or the humidity exceeds the setpoint.
Different types of thermostats, hygrostats, and hygrotherms have various switching differences and tolerances.
Users should take these characteristics into account when selecting a control device for their application.
