worchester

I have a Worchester boiler and just got the Salus ST60WBC thermostat which I have connected. However, it works in reverse order. Heating only comes on when the temperature set on the RF is lower than the room temperature (instead of the other way around). What can I do to sort this issue.

Hi there, would really welcome some advice. Tried to put the central heating on last night (first time in 8 months ish) on my worchester greenstar 28i junior and found it wasn't working. Have googled a few tips and this is a breakdown of where I'm at now. Blue light is on No flashing lights...
