during transport. If damage is
observed, or even merely suspected,
notify the carrier within 24 hours by
registered letter. Notify the local
Trane Sales office at the same time.
The unit should be totally inspected
within 3 days of delivery. If damage
is observed, notify the last carrier by
registered letter and notify the local
sales office.

TRACER CH532 offers customer the
possibility to use inputs or outputs
in order to:
- use an external water setpoint
reset using an analog input
(refer to figure 3)
- use an auxiliary setpoint
- connect a remote on/off of the unit
or a circuit
- reset faults
- connect a remote Cooling/Heating
switch
- return a circuit fault
Note: External water setpoint
Based on a external signal input, it
will be possible to offset the active
setpoint from 0°C to 20°C. This
function can be used in conjunction
with the automatic setpoint reset
function.
