Excessive Temperature Protection; Frost Protection - Samson TROVIS 5757-3 Configuration Manual

NOTICE
!
When the binary input is active, the current input cannot be used.
Functions
F05: Current input
F08: Function of binary input

2.4 Excessive temperature protection

The actuator closes the valve when the flow temperature at the flow sensor exceeds the upper
limit (GWH).
When F10 - 0 is configured, no monitoring of the flow temperature for violation of the upper
limit takes place.
Functions
F10: Upper limit (GWH)
Parameters
P05: Upper limit (GWH)

2.5 Frost protection

When the function is active, the flow temperature is monitored for violation of the lower limit.
When the temperature falls below the lower limit (GWL), the actuator opens the valve (puls-
es) until the temperature exceeds the lower limit plus hysteresis.
When F11 - 0 is configured, no monitoring of the flow temperature for violation of the lower
limit takes place.
Functions
F11: Lower limit (GWL)
Parameters
P06: Lower limit (GWL)
