Replaced battery - Now heater isn't hot.....

Well I thought I'd be good and prepared for winter and changed my battery yesterday. The old one was starting to sound sluggish on starting in the mornings and since my commute is too short to replace the charge with lights on in the dark mornings I decided to go for a brand new one for the winter.

All went well, I even remembered the radio code.

Got in this morning, started on the button, driving along nicely - but when I switched on the heater it failed to get hot, even on "Hi" setting. Engine temp was normal. In an almost 1 hour drive nothing changed. No hot air at all.

Very nice for winter..... wife already rolling her eyes and saying "Alfas..."

It's a 2004 156 2.0 JTS.

Any ideas? It's been absolutely fine up until yesterdays battery change so can't believe I will go down the thermostat route.

Have I blown a fuse? (Optimistic as ever!)

There is a reset you can go through ,you have probably mixed the settings and depending what you had these settings at when you disconnected the old battery ,it needs a bit of care on this one. There is a thread way back on this , just a case of the flap mechanism requiring programmed.
Hope that helps.

Disconnect the battery again, leave it for a few minutes then reconnect but don't switch on the ignition for at least ten minutes. You'll hear the flaps actuating as the climate control calibrates itself. All should then be well I hope.
