8.7.3 Setpoints
Comfort
The remote setpoint always acts on the lower setpoint (setpoint heating). The dead
zone between Seq1+2+3 and Seq4+5 remain the same as for the predefined
setpoints.
Thus, the current lower Comfort setpoint is
= Remote setpoint.
And the current upper Comfort setpoint is
= Remote setpoint + (Comfort setpoint high – Comfort setpoint low).
Precomfort
The Precomfort setpoints are shifted also:
Thus, the current lower Precomfort setpoint is
= Remote setpoint + (Precomfort setpoint low – Comfort setpoint low).
And the current upper Precomfort setpoint is
= Remote setpoint + (Precomfort setpoint high – Comfort setpoint low).
Economy
If sustained mode is also active, the Economy setpoints are shifted only if the
Precomfort setpoints were to lie outside the Economy setpoints.

8.7.5 Troubleshooting
Error in operation
When you exit the Commissioning menu, a check is made to see if the setpoint
adjuster is connected.
If the setpoint adjuster is connected at this point but missing later, message "[...X...]
sensor error" appears.
No. Text Effect
101… [N.X1] sensor error Non-urgent message; must not be
acknowledged
If there is no signal from the setpoint adjuster, the controller continues to work with
the internally set setpoints.
Configuration error
If more than one input is activated as remote setpoint adjuster for the same
controller, only the first input is considered.
