PTC brick heater low voltage operation


Recommended Posts

Hello,

I'm currently installing the PTC heater and was wondering how the low voltage connection should ran to the switch. If you could explain the operation so i can understand how the switch works with the heater, it would be much appreciated. 

thank you.

Hi Mitch, there are 4 connections as described in the manual.

Here is how you would wire this to a 3 way toggle.  This would give you 3 positions:  OFF, 366W and 1100W:

(Note that the enable should NOT be used to switch on/off the heater.  This should be done using the single and double stages)
