Installation and Operating Instructions
4. PARAMETER TABLE and factory default settings
IMPORTANT: Always set parameter “tC” first. As you move “tC” between settings 1 to 7, all non-relevant parameters will be masked. After setting
“tC”, it will be possible to modify all the other relevant parameters.
Once the program is completed you may want to save the parameter map to a Hot Key. If the “tC” is changed after final programming the
parameters will be changed back to the default listed below.
WARNING!!
Always switch the power OFF and then ON at the end of programming to update any parameter changes.
Make sure you connect the correct number of probes to suit the setting of parameter tC. Failure to do this will cause probe alarms
Room + Evaporator 1 + Display or AUX
Any probe alarms can be cleared by turning off / on the power
