8.1.19 How long are settings saved in the thermostat if power
fails?
User settings on the thermostat are not affected by power failure and remain until
users change the original settings.
8.1.20 How does Free cooling work?
Before the thermostat starts Free cooling, change the following extended
configuration:
● Set terminal input X1 or X2 to Outside air temperature.
● Set input Aux Out W3/UNIV to Outside air damper.
● Select Advanced Settings > Optimization, select Yes and set Min.diff.room
temp./outs.air temp.f.cool for Free cooling to the desired value.
See system setup in Commissioning for more information on configuration
changes.
When the temperature differential value (outside temperature minus room
temperature) is higher than or equal to Min.diff.room temp./outs.air temp.f.cool, the
thermostat starts cooling. When the temperature differential value is below
Min.diff.room temp./outs.air temp.f.cool, the thermostat stops cooling.
You can adjust Min.diff.room temp./outs.air temp.f.cool to influence Free cooling.
