Connections
Here is a survey of the possible connections. The texts can be read
in context with the table in point 4.
Analog inputs
Temperature sensors
Temperature sensors that can be used by thermostats for
monitoring, relay control and alarm functions (S1 - S40).
Voltage signal
Voltage signals that can be used for monitoring, relay control and
alarm functions (Volt input 1-20).
Pressure transmitters
Pressure transmitter signals that can be used by pressostats for
monitoring, relay control and alarm functions (P1 - P20).
Pulse inputs
• Energy reading
• Synchronisation
On/Off-inputs
Contact function
(on an analog input)
or
Voltage signal
(on an extension module)
On/off signals that are used for monitoring, relay control and
alarm functions (DI1-DI20).
• Defrosting signals that are used to extend alarm delays for
thermostats.
• Appliance cleaning signal to stop alarms from the thermostat.
• Signal to reset the alarm relay (mute function).
On/off outputs
Relay outputs
• Thermostat functions 1-5
• Voltage signals 1-5
• Pressostat functions 1-5
• Digital input functions 1-16
• Alarm relays 1-2

Data from this example is used on the next page.
The result is that the following modules should be used:
• AK-LM 350 Monitoring unit
• AK-XM 101A extension module with analogue inputs
Example
COP calculation on a CO2 booster system with heat recovery.
• Pressure readings can be retrieved from the other AK controllers
when the signal originates from AKS 32R and AKS 2050 ratiometric
transmitters.
• Temperature readings cannot be shared.
• Current connected capacity can be retrieved using a 0-10 V sig-
nal from the other AK controllers.
• Register the position of three-way valves (on/off signal).
