Temperature Sensors Logic
T1,0 - Return air sensor
The ambient (room) temperature can be sensed via the return air sensor.
T2,0 - Change-over sensor
Mode is automatically selected, based on the water temperature sensed by T2 (2-pipe system
only) T2 > 30°C Heat , T2 < 20°C Cool
T3,0 - Indoor coil sensor
Soft-start in Heat
When T3 rises above (or equals) 36°C The indoor fan will start working (according to FAN
ON or AUTO FAN state)
When the temperature drops below 32°C The indoor fan will turn OFF.
*When T3 is not connected:
- If AUTO FAN is selected, the indoor fan will start working 30 seconds after demand for heat.
- If FAN ON is selected, the indoor fan will work continuously.
Faults
Fault 1 - DI5,0 (N.C)
Closed (default) - System outputs work
normally.
Open - All system outputs turn off (fan speeds,
cool and heat valves).
Sample devices - Window contact, door switch.
Fault 2 - DI6,0 (N.C)
Closed (default) - "Fan only" mode – available.
Open - "Fan only" mode - not available.
Comments - Fan Only mode can be viewed
through panel .
Fault 3 - DI7,0 (N.C)
Closed/Open - Fault indication only.
Comments - The fault status (Open or Close) is
viewed through the software.
Fault 4 - DI8,0 (N.C)
Closed (default) - System outputs work
normally.
Open - When the input is open for 10 minutes -
all system outputs turn off (fan speeds,
cool and heat valves…).
Sample devices - Occupancy sensor.
