OPEn/CLoS

-

Remote contact 2 status

 

 

 

This contact is used to select a cooling only setpoint, if the unit is in cooling mode and in the remote operating control (rEM) type.

 

 

 

Contact open = csp1

 

 

 

Contact closed = csp2

2[1]

OPEn/CLoS

-

Remote contact 3 status

 

 

 

This contact is used to select the heating or cooling mode, only if the unit is in the remote operating control type.

 

 

 

Contact open: unit in cooling mode

 

 

 

Contact closed: unit in heating mode

3[3]

-

Remote contact 4 status

 

 

 

This contact is used to select the second condensing setpoint or the heat reclaim mode (for a heat reclaim unit), only if the unit is in

 

 

 

the remote operating control type.

 

 

 

Contact open = unit uses the normal condensing setpoint and is in normal mode (no heat reclaim)

 

 

 

Contact closed = unit uses the heat reclaim setpoint and is in heat reclaim mode.

OPEn/CLoS

-

Remote contact 5 status*

 

 

 

If this contact is closed, it permits limiting the unit demand, based on the demand limit setpoint, if the demand limit method by

 

 

 

contact has been selected.

OPEn/CLoS

-

Water flow and customer interlock control contact status*

 

 

 

Opening of this contact shuts the unit off or prevents its start-up and generates an alarm. It is used to control the water circulation.

6[1]

OPEn/CLoS

-

Water pump operation status. If the contact opens when the evaporator pump has received a command to operate, this trips a

 

 

 

pump failure alarm.

7[1]

OPEn/CLoS

-

Condenser water flow control. Controls the condenser water circulation.

8[1]

OPEn/CLoS

-

Control box thermostat and phase reversal interlock status*. Opening of this contact shuts the unit off or prevents its start-up

 

 

 

and generates an alarm.
