• Suitable for Honeywell 3-way changeover valve series VC DN 20 (3/4") and DN 25 (1")
  
• Ref. no.: 7098973

• Drive with EPE control (one-pole switch-on).
  If heat is needed, the controller contact is closed, RLY1 energises and closes the NO contact of switch SW3. As a result, connection B is closed and connection A is opened. If A is fully open, the cam closes switch SW1 and opens SW2.
  If heat demand is met, the controller contact is closed. RLY1 drops out and the NC contact in SW3 is closed. If connection A is fully closed, the cam closes SW2 and opens SW1. The valve is now ready again for the next heating requirement.
  In the event of a power cut, the valve remains in the current position for both drive types. If the electricity is switched on again, the valve responds to the controller state.
