11 PARAMETERS
Parameters make the ”Ech 200” a fully configurable device.
They may be modified through:
• instrument keyboard
• copy card
• personal computer (with a suitable connection and “Param manager” software)
11.1 Description of parameters
We will now look at parameters in detail, divided by category.
11.1.1 Configuration parameters
Determine the features of the machine. If one or more parameters in this category are modified, the controller must be
switched off after the modification and switched on again to ensure correct operation.
Values marked with a (*) are valid only for Ech 2xxB
“Cooling” set point
Allows the set point to be set on “cooling” mode.
“Heating” set point
Allows the set point to be set on “heating” mode
Maximum set point during “heating”
Upper limit on set point in “heating” mode
Minimum set point during “heating”
Lower limit on set point in “heating” mode
Maximum set point during “cooling”
Upper limit on set point in “cooling” mode
Minimum set point during cooling
Lower limit on set point in “cooling” mode
