My friend has an EKO40 with the RK2001U controller (2007/2008).
Yesterday he thought he had burned up a sensor and was able to located a new EKO40 water temo. sensor.
Today he was able to get a brand new temp. sensor for his boiler but when he installed the sensor has now gets an error code of E3 and is not quite sure what is going on.
Can anyone help out with this problem?
Thaanks,
Brian
