Just installed tlx 1009 room thermostat and is blowing 3 amp

This answer was rated:

Just installed tlx 1009 room thermostat and is blowing 3 amp fuse when calling for heat. It says it is 2 wire but I have 3 red, blue, and cream. The wiring diagram shows 1 2 and 3. On thermostat I have cream to com, red to on and blue to off

XXXXX XXXXX : The blue is a neutral if you need one for your stat.
XXXXX XXXXX : your new stat does not need one so you need to terminate it safely and just use the other 2 wires between c and nc.
XXXXX XXXXX : using the blue will just create a short between live and neutral
