(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:
Flow switch setting procedure
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
Setting can be executed whatever the flow status.
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
1.
For each exchanger, the setting can be done
*absolute service pressure: min 1 bar/max 11 bars
by switching pin 1 and 5 (see Figure 7) of the
sensor. Refer to the unit wiring diagram for more
information.
a.
Switch once on the button to initialize the setting
operation.
b.
Wait 1 to 5 seconds to validate the setting
initialization.
c.
Switch and hold pushed the button as much
time as the setting duration (max 65 seconds).
d.
Wait for 5 second while the sensor holds its flow
status.

e.
The sensor reverses the flow status for the time
of setting it has taken in account, count that time for
verification.
f.
Output signal goes back to normal and the
setting is effective 5 seconds later.
Note: In case that the device does not feedback the
derised setting, go back to step "a" and try again.
Note: Tracer Symbio™ 800 needs 15 continuous second
of "no-flow" to generate a "loss-of-flow" diagnostic and
shutting the unit down.
Consider to move the flow switch out of the unit in case
the setting remains non satisfying.
