Long shot question about Eberspacher Easy Start Timer hysteresis programming.
A couple of years ago I installed Eberspacher EasyStart Timer in lieu of DigiMax to control my Airtronics Espar D2 and Hydronic Espar D5. Main reason was to control both from one location.
Both units can be controlled, I gained faults readout for D5, but D2 control have very large temperature swings. Temperature display is about 4*F higher than ambient. Based on manual this higher temperature is related to the programmed hysteresis.
Easy Start Timer has programmable hysteresis with the range of 0-7*C with default set at 2*C. Unfortunately, my controller grayed these lines with dashes so I don’t know hysteresis set point.
