Hi,
After 5 years packed in a box we've just dug out our old WMR928N, replaced the batteries in the components and everything works fine except the outdoor thermo/hygro. I've looked back through some older threads here and on a few compatibility charts, but the suggested replacement THGR228 looks like an indoor unit to me, with vulnerable seals/unnecessary displays etc. and THGR122 isn't listed as being compatible.
Have I missed something?
Thanks
Sue
