PTC brick heater low voltage operation

[Mitch.EV]

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)
