Trane CH531 Installation Instructions

Installation
26 SO-SVN037A-EN
Mount transducers on the entering and leaving side water box
locations with the transducer facing upwards and connect to
unit control buss. After system is filled, loosen the transducer
in its threaded fitting. Then crack the isolation valve until water
starts dripping from threads. Close the valve and re-tighten the
transducer, and then re-open the valve for use.
High Accuracy Customer Meter Option
The high accuracy customer meter option provides an analog
input/output LLID to monitor a customer provided high
accuracy meter 0-10 Vdc or 4 – 20 mA outputs. (Rosemont,
etc.) This option allows monitoring of condenser, evaporator
flow and auxiliary heat exchangers.
Install needed DAIO LLID(s) (BRD04875) in CVRF control
panel:
1. LLID (1A21) is needed for EVAP and COND water flow.
Connect flow meter wires to 1A21-J2-1 and 1A21-J2-1 for
EVAP, 1A21-J2-4 and 1A21-J2-5 for COND.
2. LLID (1A28) is need for HR Aux/COND water flow.
Connect flow meter wires 1A28-J2-1 and 1A28-J2-1 for HR
flow or Aux COND.
Heat Recovery/Aux COND Option
When heat recovery/Aux COND option is selected, a DHVBI
LLID (BRD04874) is required as 1A29 and wires matrix show
as following:
Energy Meter Option Installation
The Trane energy meter provides instrument grade accuracy
power, volts and amps monitoring of Symbio controls
installations. It has 1% accuracy for measuring both real power
and energy and reactive power and energy. All data measured
by the meter is communicated via Modbus to Symbio control
system. For more detail information, refer to Energy Meter For
CTV Symbio 800 Upgrade Systems - Installation Instructions
(BAS-SVN224*-EN).
