3.8 - Connections at the customer terminal block
3.8.1 - Terminal block connections
The following table summarizes connections at the user
terminal block. Some contacts can be accessed only when
the unit operates in Remote mode.
Description Board Connector Remarks
Remote on/off contact SIOB J1-DI01; 32-33 Used for the unit on/off control if the unit is in Remote mode:
open = Unit is stopped; closed = Unit is allowed to start in Cooling
Remote setpoint contact SIOB J1-DI02; 65-66 Used to control the setpoint
Demand limit contact SIOB J1-DI03; 63-64 Used to control demand limit
Heat recovery SIOB J1-DI04; 73-74 Not available in software version 1.0
Customer interlock SIOB J1-DI05; 34-35 Used to control the unit by the customer:
open = Unit is stopped and an alarm is triggered (alarm 10028)
Evaporator pump 1 SIOB J2/J4-IN01/DO01; 90 Used to command the control of evaporator pump 1
Evaporator pump 2 SIOB J2/J4-IN02/DO02; 90A Used to command the control of evaporator pump 2
Alarm relay SIOB DO-05; 30A-31A Indicates alarms
Running relay SIOB DO-06; 37-38 Indicates if the unit is ready to start or operating
Setpoint reset SIOB AI10 (A1A); 71-72 Used for setpoint reset control
Occupancy override SIOB, EMM DI-01; 77-78 Enables to switch between occupied (closed contact) and unoccupied
mode (open contact), applicable to units operating in Local mode
Demand limit contact 2 SIOB, EMM DI-02; 73A-74A Used to control demand limit
Customer interlock (EMM option) SIOB, EMM DI-03; 34A-35A Used to control the unit by the customer:
closed = Unit is stopped and an alarm is triggered (alarm 10014)
Ice done contact SIOB, EMM DI-04; 75-76 Used for ice storage control
Unit partially shutdown SIOB, EMM DO-05; 30B-31B Indicates the shutdown of one of the circuits
Unit shut down SIOB, EMM DO-06; 30-31 Indicates the unit shutdown
Chiller running or ready to start SIOB, EMM DO-04; 37A-38A Output closed when the chiller is ready to start or running
Compressor A running SIOB, EMM DO-01; 37A1-38A1 Output closed when the compressor of circuit A is running
Compressor B running SIOB, EMM DO-02; 37B1-38B1 Output closed when the compressor of circuit B is running
Chiller capacity SIOB, EMM AO-01; 79+ - 79- Chiller total capacity
Space temperature SIOB, EMM AI-01; 71A-72A Space temperature input for setpoint reset function
Capacity limit (analogue) SIOB, EMM AI-10; 67-68 Analogue capacity limit command
3.8.2 - Volt-free on/off contact
When the unit is under remote control, the on/off contact is
operating as follows:
Contact Off Cooling
On/Off contact open closed
Off: Unit is stopped
Cooling: Unit is allowed to start in Cooling
3.8.3 - Volt-free setpoint selection contact
When the unit is under remote control, the volt-free contact
is used to determine the active setpoint. This dry contact is
used to switch between setpoints.

Active Setpoint
SP1 SP2
Setpoint selection contact open closed
3.8.4 - Volt-free demand limit selection contact
Up to two dry contacts can be used to limit unit capacity.
Note that the second contact is available only for units with
the energy management module. Capacity limitation with
two contacts is as follows:
Contact 100% Limit 1 Limit 2 Limit 3
Demand limit 1 contact
(LIM_SW1)
open closed open closed
Demand limit 2 contact
(LIM_SW2), EMM option
open open closed closed
Please note that limit thresholds can be defined via the user
interface in the Setpoint menu.
3.8.5 - Ice storage (EMM)
For units with EMM option, the control includes an additional
setpoint (“ice setpoint”) used for ice storage control.
Contact Cooling setpoint
Setpoint 1
(CSP1)
Setpoint 2
(CSP2)

3.8.6 - Customer interlock
The customer interlock available on the SIOB board and
connected in serial with the electrical box thermostat can be
used by the customer in order to control the state of the unit.
When the interlock is open, the unit will be stopped and the
alarm will be triggered (alarm 10028).
3.8.7 - Occupancy override (EMM)
The occupancy override contact is available in case of units
fitted with the optional Energy Management Module. When
the unit is operating in Local mode and the contact is closed,
the unit is in occupied mode. At the same time, open
occupancy contact means that the unit is in unoccupied mode.
