7.4.2 Activating the function
You can activate the function by setting the identifier of an input as a remote
setpoint (REMx).
Specify identifier and
controller
At the same time, you must specify the controller (1…2) that the remote setpoint
shall act on.
7.4.3 Type and measuring range
You can select whether the remote setpoint is an active signal (DC 0…10 V) or a
passive signal (0…1000 Ω).
Active or passive?
Additionally, you can set the input signal's range:
• MIN VAL: Lowest value at DC 0 V or 0 Ω
• MAX VAL: Highest value at DC 10 V or 1000 Ω
7.4.4 Setpoints for basic type A
The Comfort setpoints must always be entered.
Setpoints for Comfort
The remote setpoint always acts on the heating setpoint; the dead zone between
Seq1+2 and Seq4+5 remains the same as the dead zone for the permanently
preset setpoints.
• Therefore, the present Comfort heating setpoint is:
= remote setpoint
• Therefore, the present Comfort cooling setpoint is:
= remote setpoint + (Comfort cooling setpoint minus Comfort heating setpoint)
The Economy setpoints are shifted in the same way.
