Is there any way to make a Drayton wireless Digistat RF1 go down to 5c ?

[andyr123]

Happy new year everyone. - I have one of these old Drayton wireless Digistat RF1 is there any way to make the transmitter go all the way down to 5 degrees centigrade at all (documented or not documented, or taken apart and 'hacked' with shorting out something inside) the lowest I can get it to go is 15c - thanks for advice.

EDIT/UPDATE: Found out I hadnt the jumper fitted on the back of the transmitter. Now goes down to 5c minimum sorry i didnt check first before posting question.

In the back of the RF1 there should be a link (l.h side). If this has been removed
the the set temperature will not go lower than 16c.

If it is missing and you do not have a spare then it should be a simple matter to short
out the pins with silver foil or screw etc.
