9. OPTIONAL FUNCTIONS
NOTE:
The controller uses the sensor input S4 for measuring the temperature at the store
sensor.
The 3-port valve has to be mounted in a way so that the flow direction is towards the
lower store zone when the valve is without current. In order to protect the stratification
in the upper store zone, the store sensor has to be mounted in the middle store zone.
NOTE:
In cascade operation, the stratified return valve has to be connected to R2 of station 2.
