    Proline Low-temperature Thermostats 7.11 Ramp function With the ramp function, temperature changes over any time period can be conveniently entered. This is especially advantageous with very low temperature changes (e.g. 0.1°C/ day). Example: From the current outflow temperature (e.g. 242.4 °C) 200°C of cooling is to occur over 5 days. Then the temperature change is entered as 200°C and the time as 5 days.
