I've got a Vaillant Eco Tech Pro 28 Boiler. The Siemens

Customer Question

Hi.
I've got a Vaillant Eco Tech Pro 28 Boiler. The Siemens hand held thermostat control battery died. I've changed the batteries and now that appears to be working. However, the small box on the wall, which takes interactions from the thermostat controller doesn't seem to respond. There are two lights. A yellowish green one which is on and a red one above it which is flashing?
Many thanks in anticipation.
Garry.

Hi , does the receiver have a model number of any buttons on it?

Expert:  Plumberpro replied 1 year ago.
It sounds like the battery unit has lost connection with the received unit and needs reconnecting.
