not getting the counter value I am expecting

[wexfordman]

Hi,
Still sruggling with getting my heating working corretly, and I think the problem is down to counters and adding etc.
Here is my response

Code:

Get counter 91

Code:

get negative
add living_stback_tmp
set living_stback_tmp
Get counter living_dset_temp
add living_stback_tmp
Set living_stback_temp
get counter heat_hyst
Get negative
add living_stback_tmp
Set heat_livingdelta
Do heat living allign

Before I execute, my counter value are as follows

Code:

counter 91 = 22
living_stback_tmp =100
living_dset_temp=25
heat_hyst= 2

After running, my values are

Code:

counter 91 = 2
living_stback_tmp =280
living_dset_temp=25
heat_hyst = 2
livingdelta = 65535

Can anyone explain this, as these are not the results I would expect at all!
