• Switching between the main setpoint (set by keypad) and an alternative value (set by keypad to)
on the base of a digital input state (double setpoint function)
• Receiving a setpoint by a monitoring system or a BAS connected via serial line
• Resetting the setpoint of the base of analogic inputs
The control shows the source of the used (Actual) setpoint:
Local : the main setpoint set by keypad is being used
Double : the alternative setpoint set by keypad is being used
Reset : the setpoint is being reset by external input
The following setpoint reset methods are available to modify the local or double setpoint:
None : local or double setpoint are used on the base of the double setpoint digital
input. This is called “base setpoint”
4-20mA : base setpoint is modified on the base of an user analog input
OAT : base setpoint is modified on the base of outside ambient temperature (if
available)
Return : base setpoint is modified on the base of evaporator entering temperature
Network : the setpoint sent by serial line is used
In the case of a failure in the serial connection or in the 4-20mA input the base setpoint is
used. In case of a setpoint reset, the system display will show the type of reset.
6.4.1. 4-20mA setpoint override
