Analogue inputs - Temperature sensors
AI3 Room humidity sensor
AI4 Duct humidity sensor (limiting sensor in supply
air duct)
Analogue inputs - Temperature sensors
AI5 Outdoor temperature
AI6 Supply air temperature
AI7 Room temperature
AI8 Frost protection temperature. When frost
protection function has been selected
or
High temperature limit (When using an
electric heater)
Digital inputs - operation and alarm indication
AI1 Fan monitor or pressure switch Supply air
fan.
AI2 Fan monitor or pressure switch Exhaust air
fan.
DI1 Filter guard(s)
DI2 Circulation pump monitor, heater circuit
DI3 Input for alarm from chiller(s)
DI4 Rotation sentinel or
Ice build-up sentinel for heat exchanger
DI5 Fire alarm
DI6 External alarm,
external switches ”not in Auto position”
or
end-position indication for fire-damper (for
fire-damper exercising).
DI7 Button or timer for extended running time (at
single speed) / Extended running time high
speed for two- speed fan systems).
DI8 Button or timer for extended low speed
running time (for two-speed fan systems).
4 analogue sensor inputs Pt1000
2 analogue 0...10V inputs
10 digital inputs
3 analogue outputs 0....10V
7 digital outputs
The controller has temperature control with up to three sequences, humidity control (humidification,
dehumidification or humidification in combination with dehumidification by using the cooling output, control of
DX-cooling,one- or two-speed operation, cooling recovery function, night setback etc).
Analogue outputs - output signal 0...10 V
AO1 Y1 - Heating, cooling or damper
AO2 Y2 - Heating, plate exchanger, rotating exchanger,
liquid connected exchanger, damper or cooling
AO3 Y3 – Heating, cooling or not used
AO6 Humidification / Dehumidification
Digital outputs
DO1 Control supply air fan or
Supply air fan high speed for two-speed fans
DO2 Control exhaust air fan or
Exhaust air fan high speed for two-speed fans
DO3 Control circulation pump or
Electric heating interlock
DO4 Control chiller 1 (DX) or
Supply air fan low speed for two-speed fans
DO5 Control chiller 2 (DX) or
Exhaust air fan low speed for two-speed fans
DO6 Control external frost protection or
Fire damper exercising
DO7 Alarm output
Example of an application
suitable for controlling by
the C30 model.
