CONNECTIONS FOR SIGNAL AND PULSE OUTPUT
The digital heating filling station can be integrated into a building control system via the
signal output (R for relay).
For versions with battery PT-DA and PT-DB: 3 V / 0,1 A (VBAT)
For versions with 24 V power supply PT-DBP and PT-FCS(D): 24 V / 0,1 A (VBAT)
Open-Collector
Pin 1: b
Pin 2: Current flows with signal → battery -
The signal is triggered when the red LED lights up: Electrical conductivity is too high or the
calculated residual capacity is zero or the max. replenishment quantity per week is excee-

SIGNAL OUTPUT R
CONNECTIONS FOR SIGNAL AND PULSE OUTPUT
The pulse output can be used to transmit the flow rate of the Digital Heater Filling Station
to external electronics.
For all versions 3 V / 0,1 A (VBAT)
Open-Collector
Pin 1: b
Pin 2: Current flows with signal → battery -
A 3V pulse is generated per liter of make-up water flowing through.
