Remote contact 1 status.
If the auto cooling/heating changeover function is not selected (User Configuration 1), this contact is used to start and
stop the unit. If the auto cooling/heating changeover function is selected, this contact is multiplexed with contact 2 to
permit starting and stopping the unit and the selection of heating/cooling/auto. This contact is only valid, if the unit is in
the remote operating control (rEM) mode. See section 3.6 for the description of the connections of this contact.
Remote contact 2 status.
If the auto cooling/heating changeover function is not selected (User Configuration 1), this contact is used to select the
heating or cooling mode. If the auto cooling/heating changeover function is selected, this contact is multiplexed with
contact 1 to permit starting and stopping the unit and the selection of heating/cooling/auto. This contact is only valid, if
the unit is in the remote operating control (rEM) mode. See section 3.6 for the description of the connections of this
contact.
Remote contact 3 status.
The operation of this contact depends on the unit type.
Single-circuit unit: this contact can be used either to limit unit demand or to select a setpoint, as described in User
Configuration. If this contact is used for selecting a setpoint it is only active if the unit is in the remote operating control
mode. If the contact is used to limit the demand of the unit, it is active in all operating types.
Open contact: unit capacity is not limited or unit control is based on setpoint 1.
Closed contact: unit capacity is limited at limit setpoint 1 or unit control is based on setpoint 2.
See section 4.3.11.3 for the configuration of contact 3 - section 5.6.1 for the description of the setpoint selection -
section 5.7 for the description of the demand limit function and 3.6 for the description of the connection of contact 3 for
single-circuit units.
Dual-circuit units: this contact is multiplexed with contact 4 to permit the selection of a demand limit point. This
contact is active in all operating types. See section 3.6.5 for the description of this contact and section 5.7 for the
description of the demand limit function.
Remote contact 4 status.
This contact is only used for dual-circuit units: this contact is multiplexed with contact 3 to permit selection of a
demand limit value. This contact is active in all operating types. See section 3.6.5 for the description of this contact
and section 5.7 for the description of the demand limit function.
Remote contact 5 status.
This contact is only used for dual-circuit units: this contact is multiplexed with contact 6 to permit selection of a
setpoint. This contact is only active in the remote operating control mode. See section 3.6.6 for the description of this
contact and section 5.6.1 for the description of the setpoint selection function.
Remote contact 6 status.
This contact is only used for dual-circuit units: this contact is multiplexed with contact 5 to permit selection of a
setpoint. This contact is only active in the remote operating control mode. See section 3.6.6 for the description of this
contact and section 5.6.1 for the description of the setpoint selection function.
Interlock status. When this contact opens the unit stops or is prevented from starting and an alarm is created. This
contact is used to control the water flow. In addition, a customer safety device can be connected in series with this
contact (see section 3.6).
Water pump run contact status. When this contact opens while an evaporator pump has received a command to be
on then a pump failure alarm is tripped.
