Table 13
Digital ->
Readout of current condition of digital inputs:
Di1(D1) – Electric heater overheating thermostat [S4F] (in case of two heaters signals are connected
in series), normally closed (factory setting)

Analog ->
Readout of current condition of analogue inputs:
Ai1(Ain1) – signal from humidity sensor
- or pressure transmitter
- or CO2
- or PM converter
(depending on the input function selection)
Ai2(Ain2) – signal from humidity sensor
- or pressure transmitter
- or CO2
- or PM converter
(depending on the input function selection)
Sensors ->
Current measurement from temperature sensors:
PT1(P1) – temperature of air supplied to the room [B1] PT2(P2) – temperature of air
extracted from the room [B2] PT3(P3) – temperature of external air [B3]
PT4(P4) – temperature of air extracted [B4] downstream the heat recovery (in a system
equipped with preliminary electric heater drop of B4 temperature below the limit initi-
ates the anti-frost protection cycle)
PT5(P5) – optional master temperature [B5] (room temperature)
HMI (CON) – temperature of air in a room (sensor in HMI programming device)
