Thermostat settings

[panas]

Hi!
I think it is easy for you. What does it mean? (For K50 thermostat)

Cold Out -27ºC
Cold In -17ºC
Warm In -12ºC

And If for example I put number 6 ( from 7) on the thermostat settings how it should work?

Thank you

Ranco VF3, K50-P1117 is a similar thermostat.
Cold out is the coldest setting the thermostat will cut out at -27degC (no 7 on your dial)
Cold in (warm out) is the temperature the thermostat will cut in at if set at no 7. (-17deg.C) or the temperature it will cut out at on the warm setting (-17deg.C)
Warm in is the highest temperature the thermostat will cut back in at no 1 setting. (-12 degc)
Hope this help and i have explained it to you in simple terms.

Answering the second part of your question
On a no 6 setting, temp will work as follows

Cut out = 17 + (27-17) x 6/7 = 25.6 deg.C
Cut in = 12 + (17-12) x 6/7 = 16.3 deg.C

Cut out will always be between -27 and -17 deg.C
-27 no 7 & -17 no 1
Cut in will always be between -17 deg.C and -12 deg.C
-17 no 7 & -12 no 1

The setting you chose will be a ratio of these settings as calculated above.
