9.2.2 Setpoints
You can assign individual setpoints for the Comfort and Economy modes. We
distinguish between the following setpoints in the 2 modes:
Preselections
– SETHEAT lower setpoint "Heating" (sequence 1+2)
– SETCOOL upper setpoint "Cooling" (sequence 4+5)

Influences on the
setpoints
The following functions can have an influence on setpoints:
• Locking a sequence by the outside temperature OT (refer to section 9.8)
• Remote setpoint, absolute (refer to section 7.4)
• Remote setpoint, relative (refer to section 7.5)
• Summer / winter compensation (refer to section 9.9)
Setpoint limitations To save as much energy as possible, the setpoint range adjustable by the user can
be limited. This function is made available in Comfort and Precomfort modes. This
setting can only be made with controller 1 in basic type A.
Using SETHLIM, the cooling setpoint can be limited to a minimum value. This
means that this minimum value cannot be crossed, neither by the relative setpoint
adjuster, the absolute setpoint adjuster, summer / winter compensation, nor other
functions. The factory setting is 0 °C, which means that the function is deactivated.
Using SETHLIM, the heating setpoint can be limited to a maximum value. This
means that this maximum value cannot be crossed, neither by the relative setpoint
adjuster, the absolute setpoint adjuster, summer / winter compensation, nor other
functions. The factory setting is 250 °C, whichmeans that the function is
deactivated.
