Frequently Asked Questions
What is the difference between a thermostat and a hygrostat?
A thermostat switches based on temperature, while a hygrostat switches based on humidity. Both help maintain a stable climate inside the control cabinet and prevent condensation.
What are thermostats used for in a control cabinet?
They control, for example, heaters, fans, or cooling units to maintain defined temperature ranges. This reduces overheating and cooling issues.
How do I select the appropriate control range and switching capacity?
The control range must match the expected temperatures/humidity levels, and the switching capacity must match the connected loads. Also check the supply voltage and contact type.
Where should a thermostat or hygrostat be mounted in the control cabinet?
The ideal position is one that measures the representative cabinet temperature or humidity without being directly influenced by localized heat sources. Correct installation improves control quality.
Can a control system extend the service life of components?
Yes, stable temperatures and low humidity reduce material stress, corrosion, and malfunctions. This often leads to fewer failures and lower maintenance costs.
Which thermostat do I need for which product?
The right thermostat depends on the application (heating or cooling), the required temperature range, and the installation in the control cabinet. For example, a normally closed (NC) contact is typically used for heating systems, and a normally open (NO) contact for filter fans—if you’re unsure, we’re happy to help you choose the right one.
