If the comfort setpoint value is used as a basis:
If the comfort setpoint value is used as a basis, the reduction/increment of the value is
set.
Setpoint values for frost/heat protection (building protection)
The building protection mode is for example used as long as windows are opened for
ventilation. Setpoints for frost protection (heating) and heat protection (cooling) are
determined which may not be modified from outside (no access via operating devices
etc.). The building protection mode may be activated with delay, which allows you to
leave the building before the controls switch to frost/heat protection mode.
General control variables
This setting appears for the control types "Heating
and
Cooling" only. Here, you can
decide whether to use a common control variable for heating and cooling. If the 2nd
level has a common control variable, you also determine the control mode of the 2nd
level here.
When using the control variable for a 4/6 way valve, the following applies:
0%...100% heating = 66%...100% control variable
OFF = 50% control variable
0%...100% cooling = 33%...0% control variable
Reduce heating setpoint (in 0.1°C)
(for heating)
0…200; 50
Increase cooling setpoint (in 0.1°C)
(for cooling)
0…200; 60
Setpoint frost protection (in 0.1°C)
-300…800; 70
Activation delay
less than • 5 s • ... • 5 min • … • 2 h
Setpoint heat protection (in 0.1°C)
-300…800; 350
Activation delay

For heating and cooling
• separate control variables are used
• common control variables are used for
Level 1
• common control variables are used for
Level 2
• common control variable are used for
