Fan low (3A)
Fan medium (3A)
Fan high (3A)
Temperature Sensors Logic
T1,0 - Return air sensor
T2,0 -Outdoor sensor
T3,0 - Indoor sensor
Deicing (Compressor and outdoor fan are inactive)
In Heat mode:
-0ºC/ºF < T2 < 16ºC/61ºF → 5 minutes defrost / 22 minutes break
In Cool mode:
-0ºC/ºF < T3 < 8ºC/46.5ºF → Deicing occurs until T3 rises above 8ºC/46.5ºF
Overheat protection:
In Heat mode (Compressor, H.Elements and Outdoor fan inactive):
Overheat starts when T3 > 68ºC/155ºF and stops when T3 < 55ºC/131ºF
In Cool mode (Compressor, Stop, Indoor and Outdoor fans active):
Overheat starts when T2 > 68ºC/155ºF and stops when T2 < 55ºC/131ºF
Note: T2 and T3 can be configured through the protocol to be used as indication only (without deicing
and overheat protection)

connecting the wall panel.
DIP switch Configuration (S2)
S2.1 –HC (Heat–Cool) or HP (Heat Pump)
OFF - HP configuration
ON - HC configuration
In HC configuration: DO5 = H.Element 1, DO3 = H.Element 3
In HP configuration: DO5 = Heat Pump, DO3 = Outdoor Fan
S2.2 –Electric Heater or Oil/Gas Heater (in HC)
ON - Oil/Gas
OFF - Electric
S2.3 – Instance number configuration
OFF - Instance number by protocol
ON - Instance number = MAC Address+600
S2.4 – “End of network” configuration
ON - End of network
OFF - Not end of network

Default
Fault 2 – Window contact (N.C.)
Fault 3 – Flow sensor (N.C.)
Digital input 1 – Indication only
Digital input 4 – Compressor delay
Digital input 5 – Fan speeds
Digital input 6 – Heat pump config.
Digital input 7 – Indication only
Digital inputs
DI1 – Indication only thorough protocol
DI2 – Window contact (N.C.)
Turn all outputs OFF or switch to Economy (selectable through protocol).
DI3 – Flow Sensor (N.C.)
Fault 3 (Flow sensor) – Turn compressors and heat elements OFF.
DI4 – 3.5 Minutes Compressor delay (Open – with delay)
DI5 – Fan speeds (Open – 3 Speeds, Close – 1 Speed)
DI6 – Heat pump config (Open – Active in cool, Close – Active in heat)
DI7 – Indication only thorough protocol
DI8 – Occupancy sensor
When the digital input is open for 10 minutes, all outputs turn OFF or controller
switch to economy (Selectable through protocol).
Short the (DI8,0) terminals, only when an occupancy sensor is not connected
