… 6  Electrical connections 

Electronic Unit EBN862 (Contrac) 

 

  

 

Note 

•  The electrical connection is provided by a universal plug on the control actuator and the screw terminals on the electronic unit. 
•  If you are using a separate heat supply, the heater must be protected with a 2 to 6 A medium time-lag fuse (e.g. NEOZED D01 E14).
