7 OPERATION LOGIC
The following operation logics are enabled by the master controller (CB), mounted on the front panel of the unit.
7.1 DYNAMIC SETPOINT ADJUSTMENT
The controller can change the setpoint by adding a value depending on the outdoor air temperature sensor. In this case, you need
to change the values of the parameters from
b08 to b14 following the indications below (settings to be done by the installer):
Parameters of the controller PAr->rE->
• b08 = dynamic setpoint, enabled = 1/ disabled = 0 (this parameter must be disabled in the case of the use of climatic
compensation by the optional remote touch screen panel Evo Touch).
•
b09
=
offset max in cooling mode operation.
• b10 = offset max in heating mode operation.
• b11 = Outdoor temperature setting in cooling mode.
• b12
=
Outdoor temperature setting in heating mode.
• b13 = Temperature difference in cooling mode operation.
• b14 = Temperature difference in heating mode operation.
Please see paragraph 11.4 for to change the parameters.
