Description

fFrostProtectionSetpoint

REAL

Frost protection setpoint, e.g. for heating circuits in protection mode.

fTWth

REAL

Current value of the outside temperature.

fTWthLowLimit

REAL

Lower limit value of the outside temperature. Below this value, all frost protection functions in HVAC systems are activated.

bTWthLowLimit

BOOL

The variable is TRUE if the outside temperature is below the value of fTWthLowCrit.

fTWthDamped

REAL

Current value of the damped outside temperature.

bTWthDampedLowLimit

BOOL

The variable is TRUE if the damped outside temperature is below the value of fTWthLowCrit.
