Having trouble with the controller on my EKO 25 it is the newer style RK-2001U. I thought maybe it was the temp probe since the numbers were flipping all around but I tested the probe and it is OK. Now sometimes the controller will alternate between showing the boiler temp and the setpoint (C189 in my case), without touching any buttons. I hear the relays clicking on and off afraid I'm going to wear them out.
Anyone have any suggestions?
How long is the warranty?
