19.1
Model with 5 internal relays and 1 modulating output (0..10V or 4..20mA)
MF ID1, MF ID2, MF ID5
= multifunction digital inputs
ID3 =
high pressure digital input
ID4 =
low pressure digital input
RL1
= compressor relay
MF RL2, MF RL3, MF RL4, MF RL5
= multifunction
relays
MF o.c. out
= multifunction open collector output (for
external relay)
Pb1, Pb2, Pb3, Pb4
= NTC probe or digital input
Tk
= output for external fan speed controller
Analog output
= output 0..10V / 4..20mA for external fan
speed module (for condenser fan or modulating
evaporator water pump)
