Trane ReliaTel Diagnostic Manual page 35

Note: Version 1.1 and 1.3 RTRM do not provide Heat, Cool, Service, Cool Fail, Heat Fail indications
COMM3/4 and COMM5 Communication Interface Module use MODBUS communication directly
with the RTRM. Tracker and Tracer require inputs as shown:
Table 4. Default operation for ICS control:
J6 input/connection
J6-1- Zone temperature
J6-2- Common terminal for J6-1, J6-3, J6-4, J6-5
J6-4 Mode input (VAV units)
Note: VariTrac does not require any input to J6
Table 5. Conventional ZSM thermostat-default operation
Input/connection
G (Indoor fan)
The purpose of G is to provide a way to run the fan continuously
See section on Conventional Thermostat Operation for more on this.
Table 6. 27.5-50 Ton VAV Units
Input/connection (27½ to 50 ton VAV only)
Default mode input jumper J6-2 to J6-4.
Zone temperature input J6-2 to J6-1
RT-SVD03G-EN
for Programmable ZSM. Later versions (with a higher number) do.
ReliaTel Refrigeration Module (RTRM)
if no input this happens:
Unit stops unless Tracer is providing zone temperature input (CV units)
Unit stops unless Tracer is providing zone temperature input (CV units)
or mode input (VAV units).
Unit stops unless Tracer is providing a Mode input.
if no input, this happens:
A heat or cool call will also enable the fan.
If no input, this happens:
Without a mode input, the unit will not run.
Unoccupied mode (short J6-11 to J6-12).
Gives cool fail diagnostic.
