3.5 Minutes delay for compressor (F4)
F4 Open – With delay
F4 Close – Without delay (for test only)
HC (Heat–Cool) or HP (Heat Pump)
HP – JP4 Open , JP5 Short
HC – JP4 Short
In HC configuration: output 14 = H.Element 1, output 16 = H.Element 3
In HP configuration: output 14 = Heat Pump, output 16 = Outdoor Fan
Occupancy Sensor
When the IR (N.C.) input is open
for 10 minutes, all outputs turn Off.
Short the (-12V) and (IR)
connectors, only when an
occupancy sensor is not connected
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, H.Elements, Indoor and Outdoor fans inactive):
Overheat starts when T2 > 68ºC/155ºF and stops when T2 < 55ºC/131ºF
