I am having trouble getting my Espar hydronic heater to turn on. It has an easy start control module, which works with the Espar Airtronic or Hydronic heaters. I have a Hydronic M ll heater.
The error message n51 comes up which indicates "no communication". Both the 5 amp and 25 amp fuses are good. Voltage is at 13v. All electrical connections and ground connections have been cleaned and lubricated.
Has anyone else had this problem?? Got any solutions??
Thanks
