9.6 Modifying the dynamic setpoint
The regulator allows the setpoint to be modified by adding an offset to the external air temperature probe reading. To use this function, the
user has to set the values of parameters b08 to b14 following the instructions provided below (modifications to be made by the installer).
Parameters of regulator PAr->rE->
• b08 = dynamic setpoint enabled=1 / disabled=0 (must be disabled if weather compensation from the optional CRH remote
keypad is used).
• b09 = cooling maximum offset.
• b10 = heating maximum offset.
• b11 = External temperature setting in cooling mode.
• b12 = External temperature setting in heating mode.
• b13 = Temperature delta in cooling mode.
• b14 = Temperature delta. in heating mode.
Modifying the setpoint in relation to the external temperature:
9.7 Modifying the setpoint from 0-10V input
Another type of adjustment allows to change the set-point by adding (or subtracting) a value according to the 0-10V input (if enabled). To
enable the function, set H21=40, and if necessary change the value of the parameter b15 (0-10 range), taking into consideration that:
• with 0 Volt input the current setpoint will be: (Coo/Hea) setpoint set – b15/2
• with 5 Volt input the setpoint will be the one set (Coo/Hea)
• with 10 Volt input the current setpoint will be: (Coo/Hea) setpoint set – b15/2
