installed in the controller.

Factory setting

If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you recon nect the supply voltage

Error messages

The controller can give the following messages:
E1
E12
Error message
E21
E22
A1
A2 Alarm message

1)
If E21 is detected. EKC 347 will force the valve to close or open the valve depending
af n35
If Low pressure has been selected. (n35=0)
The valve is forced to fully closed, however if Min. Opening Degree (n33) is higher
than 0 the valve will open to the value of n33
If High pressure has been selected. (n35=1)
The valve is forced to fully open, however if Max. Opening Degree (n32) is lower than
100 the valve will open to the value of n32
