problems with deltas???

[dangerrrr]

is anyone else having any problems with the delta settings.

im trying to tell my heaters to go on at 25c and go off at a delta MAX of 1. which would be 26c. but they go on at 24.9c and off at 25c.

im also running two other programs under the temp programs and they seem to be running fine!

can anyone help me?

thanks!

Did you set your Ref. point to 25.5? Then set your Min Delta to 0.5 and Max to 0.5 then that should keep it in a range of 1 degree.

for some reason it seems to switching off when it reaches the refernce point regadless of the max delta.

im currently got it set at a reference of 25. and a MAX delta of 1.
the heater comes on at 24.9 and then goes off at 25. the MAX delta is having no effect for some reason.

ive managed to get around it by doing this.
ive set the reference at 26 and a MIN delta of 1.
the heater now comes on at 25 and doesnt switch off untill it reaches the reference of 26.

is this the correct way to set it up. or are my deltas not working???

thanks

Hi dangerrrr,

your last program is the right one, delta min 1, reference at 26.
