Tiny Interface Relais switch

Dear gyus,

refering to the old forum I created the MOFSET relais switch as described in the forum link behind here:
http://forum.rajiva.de/forum/phpBB2/viewtopic.php?t=4001

However I could not get the original MOFSET, so I used an alternative model.
Original: http://pdf1.alldatasheet.com/datasheet-pdf/view/61952/GE/BS250.html
Alternative: http://www.datasheetarchive.com/BS170RL1-datasheet.html

My Problem ist that the Relais for the heating attached on the second connector of the Tiny is switched permanent and cannot be controlled by the handbox. I checked the soldering many times and could not find any failure. Temperature and Hunidity works perfect so far.
Does someone have an idea?

Thanks

Problem solved, I switched to a BC548C and now I can control the heater perfect,...
