Heating Not Coming On
Had a new boiler fitted yesterday (Worcester Bosch Greenstar i). This was fitted with the Tado Themorstat and extension kit. Internet bridge has 3 lights on, thermostat is paired (the chain links on the display are joined together) and the extension kit light is "breathing". Yet when we turn the thermostat temperature up the heating doesn't kick in. Have tried switching things off and on and rebooting. Any ideas?
