6.3.1 Cooling Mode
For any type of cooling there is an outdoor air lockout temperature below which cooling will not
be allowed. Note that the default is high. This is to insure that at start up, you can start your
fans without worrying if the tempering will also start. This value will need to be lowered to an
acceptable value.
6.3.2 Cooling Control Type
For each type of cooling, you can choose a control type.
Control types available:
u
CA: Be sure to install your CA temperature sensor far enough down the duct
to prevent over-cycling
u
RA: If you are only feeding one space this is a useful control method.
