Published/Edition: December ISBN/Book No.: When the contactor opens, the metal core that is used to pull in the contactor in will create a quick induce voltage in the coil as the iron moves quickly within the coil cause a spike voltage.
The varistor will clip the voltage to a particular level protectecting the control circuit. The created voltage can be much higher than the control. great interest when discussing the application and selection of active chilled beams, particularly when the building in question is located in a humid climate.
As most designers and end users have concerns about the potential for condensation, it is common for the concept of using a condensate pan to be considered. To me, using a condensate.
HVAC Call Center Services Whenever an air conditioning or heating unit goes down, you need to rescue the homeowner or property manager looking for help.
So be an HVAC hero with AnswerNet’s Call Center Services. AnswerNet’s customizable. Check the power out to t-stat on the R and common terminal of t-stat. Or check one of the contactor coil wires to ground. The coil is an electro-magnet so 24 volts makes it pull in the contactor and makes the connection across the contacts.
