Hi guys its me again fitted the new vt9 thermostat last night and waited to see if it switched off ok
voila success all working well.. connected wires to pins 4 and 6 as you guys suggested..checked temp today and its a constant 5c wife happy im happy bank happy...even got the light to work when u open door....changed bulb but found the sw that opens when door opens was jammed took to bits put back together now all fine...
think total cost was £5.99 thermostat £2.25 for bulb not a bad price to pay...
thanks to all of you that helped me through this...
cheers agn..
