(1) Conditions: Water entering/leaving temperature: 7/12 °C, Air inlet temperature 27/19°C DB/WB - Nominal air flow
(2) Conditions: Water entering/leaving temperature: 50/45 °C, Air inlet temperature 20°C DB - Nominal air flow
(3) At high speed with nominal air flow.
(4) Water entering/leaving temperature 90/70 °C, air inlet temperature 20 °C DB, Nominal air flow.
(5) A rectangular glass wool duct 1m50 long is placed on the blower.The measurement is taken in the room containing the blower unit.
Heat exchanger operating limits:
FWD:
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
*absolute service pressure: min 1 bar/max 11 bars
External setpoints & capacity outputs (Optional)
ECWS and ECLS Analog Input Signal
Wiring Details
Both the ECWS and ECLS can be connected and setup
as either a 2-10 VDC (factory default), 4-20 mA, or
resistance input (also a form of 4-2OmA) as indicated
below. Tracer TU must be used to set Analog Input
Signal LLID type.
This is done by a setting change on the Custom Tab of
the Configuration View within Tracer TU.
Priority
When Not Installed, external chilled water setpoint
analog input, external demand limit setpoint analog
input and auxiliary binary input setpoint enable will not
be used (Front panel or BAS sources used, depending
which one is valid).
Setpoint Source selections are: BAS/Ext/FP, Ext/FP, or
Front Panel
When Installed, both analog I/O and binary will be used,
with respect of following status:
• External chilled water setpoint: IF it is the
highest priority and it is a valid source THEN
use this external setpoint for active chilled
water setpoint.
• External demand limit setpoint: IF it is the
highest priority and it is a valid source THEN
use this external setpoint for active demand
limit setpoint.
• External auxiliary chilled water setpoint enable
input: IF setpoint source is set to external/Front
Panel or Front Panel THEN:
− IF input open, use the next highest
priority setpoint source (see priority list
below)
− IF input closed, use the auxiliary chilled
water setpoint
Note on auxiliary chilled water setpoint source:
• Not Installed: auxiliary chilled water setpoint
not used
• Front Panel: front panel auxiliary chilled water
setpoint used instead of front panel chilled
water setpoint
• External: the setpoint used will depend on
binary input state.
Priority (from highest to lowest):
• BAS communication (Bacnet, Lonworks or
Modbus)
• Ice Making
• External setpoints
• Front Panel setpoints
Important:
For proper unit operation, BOTH the ECLS and ECWS
settings MUST be the same (2-10 VDC or 4-20mA), even
if only one input is to be used.
