10.3 Simulation functions
10.3.1 Protection functions
ID
Object name
R/W
Description
BO,3
Simulate Overheat Protection W
0: Disable overheat protection (default)
1: Enable overheat protection
When enabled, the valve is closed. The function is only active for underfloor
heating application.
Actual status is read via BI,6 (Warning Flow Temperature High).
BO,4
Simulate Frost Protection
W
0: Disable frost protection (default)
1: Enable frost protection
When enabled, the valve opens fully. The function is only active for heating
coil application.
Actual status is read via BI,7 (Notification Coil Frost Risk Detected).
