Question about Water Heaters
Alpha model HE CB25 - DHW is fine, but after setting up wireless programmer to be ON and room its thermostat to 22 deg min., 25 deg max, the heating fires up but then shuts down after about 2/3 minutes, even though room temp on programmer indicates only 18 deg.
I have tried another programmer i.e. transmitter, from an identical boiler with same result.
I have not changed the receiver.
It sounds like the problem may be in the boiler and not the controller itself. Do you kno which is are the two wores that are the r-w for the thermostat take and purt them together and see if the boiler stays on or shuts off like it does with the thermostat. If it does then replace the reciever. If it doesn't then you have another problem. Good Luck
