HOW TO LOCK THE PARAMETERS
Locking the parameters ensures their settings are not changed by accident.
When the parameters are locked, the only settings that can be changed are
the single set point (if the temperature curve is deactivated) and the single
stage 1 minimum speed (if the minimum speed curve is not effectively in
operation). All other parameter settings can not be changed.
To lock the parameters:
Set switch # 1 to ON.
To unlock the parameters:
Set switch # 1 to OFF.
FACTORY SETTING : When the controller is shipped from the factory,
switch # 1 is set to OFF (the parameters are unlocked).
